# Quantitative Aptitude: Data Interpretation Questions Set 42

Data Interpretation Questions (DI) for IBPS PO 2017, IBPS Clerk, NIACL, NICL, SBI PO, RBI Grade B, Dena Bank PO PGDBF, BOI, Bank of Baroda and other competitive exams.

Directions (1-5): The below bar graph shows the production (in thousands) of different items by a manufacturing firm in 6 different months.

1. If only 80% of the pencils manufactured in may are suitable for sale and a discount of 10% is given on the MP, then what is the profit% ?
A) 30
B) 10
C) 8
D) 12
Option C
Solution :

Pencils produced in may = 70000
suitable to sale = 80% = 56000………total CP ( including defected produce) = 70*2000 = 140000
MP = Re. 3 per pencil ..discount 10 % so SP =Re. 2.7
Total SP. 2.7*56000 = 151200 ..Profit = 11200..profit % = 11200*100/140000 = 8
2. In how many months scales manufactured are greater than average scales manufactured over the given months?
A) 3 months
B) 5 months
C) 2 months
D) 4 months
Option D
Solution :

Average production over the given months (scales) 265000/6 = 44000(appx)
jan ,april , may and june are the months .
3. If in July production of markers increases by 20% , scales by 15% and sharpeners by 12% over the previous month , then What is the total production of all the three products in july ?
A) 115950
B) 114950
C) 119450
D) 115490
Option B
Solution :

In june markers produced = 20000 ..increase in july â€“ 20% i.e 4000
scales produced in june = 45000 …increase in july – 15% i.e 6750
sharpeners in june = 35000…….increase in july -12% i.e 4200
total in june ..1,00,000 ….increase in july ……..14950 >> increased production = 114950
4. By how much is the the production of all the items in june less than the production in april (in rupees) ?
A) 198500
B) 189500
C) 158900
D) 185900
Option A
Solution :

production in april……….june ……change…….amount ( in CP)
. Â  Â  pencils……..45………….65………..(-20)………..(-40)
. Â  Â  Â erasers…….30…………35………..(-5) …………..(-7.5)
. Â  Â  markers……60…………20…………(+40)………….(+240)
. Â  Â  Â scales………45…………..45…….no change
. Â  Â  Â sharpeners.40…………..35………….(+5)………….(+6)
total change …………………….246- 47.5 = 198.5 *1000 = 198500 rupees
5. What is the total revenue generated if all the items produced in February are sold (assume MP to be SP here) ?
A) 945000
B) 949000
C) 995400
D) 954000
Option B
Solution :
revenue from pencils = 40*3 = 120
revenue from erasers = 35*2.4 = 84
revenue from markers = 70*9 = 630
revenue from scales = 35* 2 = 70
revenue from sharpeners= 30*1.5 = 45
total = 949 ….multiply by thousand = Rs. 949000

Directions (6-10):Â Read the below data carefully and answer the following questions :

The line graph indicates the no. of days taken by six boys to complete a work.

The chart below shows the number of days taken by six girls to complete a work.

1. If pulkit and paras started to work and after 2 days they were replaced by neha, ruhi and happy then they stopped , how much work is still left ? (Neha, Ruhi and Happy worked for 2 days together)
A) 1/10
B) 1/6
C) 1/9
D) 1/12
Option B
Solution :

Let work = 180 units
pulkitâ€™ 1 dayâ€™s work ……….20 ( work/ no. of days taken)
parasâ€™s 1 dayâ€™s work ……..20
nehaâ€™s 1 dayâ€™s work……….7.5
happyâ€™s 1 days work……..7.5
ruhiâ€™s 1 dayâ€™s work ……..20
paras and pulkit worked for 2 days…..(20+20)*2 = 80…remaining work = 100
now for 2 days ( 7.5+7.5+20)*2 = 70 …..remaining work = 30 ..so 30/180 = 1/6
2. If all the boys work together then time taken by them will be how much less than the time taken by purvi, hema , neha and happy together to do the work ?
A) 2 * 2/5 days
B) 2 * 3/5 days
C) 2 * 1/5 days
D) 2* 4/5 days
Option C
Solution :

total days taken by boys to do the work = 180/100 = 9/5 days
days taken by 4 girls = 180/45 = 4 days …difference = 4-9/5 = 11/5 days
3. Pradeep and Nikku started work. Pradeep worked at 120% of his efficiency and Nikku at 5/6 of his normal routine work. They started work on alternate days starting with Pradeep. How many days will be taken by them to complete the work?
A) 10* 4/5 days
B) 10* 5/6 days
C) 10* 3/4 days
D) 11 days
Option B
Solution :

Pradeepâ€™s one dayâ€™s work ………..180/12 = 15 units
N one dayâ€™s work…………….180/10 = 18 units
now, Pradeep works at 120% of 15 = 18 units
Nikku at 5/6 of 18 = 15 units
Pradeep + Nikkuâ€™s 2 daysâ€™ work = 33
In 10 days ……………….33*5 = 165 units
Remaining ………15 units ….Pradeep does…18 days a day so to do 15 units He will take 5/6 days therefore total time taken = 10* 5/6 days
4. How many days will it take to complete the work if Punit does the 25% of the work alone and 10% is done by Nikku alone and the remaining is done by Suman ??
A) 19 days
B) 16 days
c) 13 days
D) 17 days
Option D
Solution :

Punitâ€™s 1 dayâ€™s work ………15 units so to do 25% work ( assumed total work = 180) = 45 he will take 3 days
to do 10% work..i.e 18 units nikku will take 1 days …noe remaining work = 180-63 = 117
to do 117 , suman will take 117/9 = 13 days ( sumanâ€™s 1 dayâ€™s work = 180/20 = 9 units)
Total days = 3+1+13 = 17 days
5. Ashu started working alone at his normal efficiency but after 5 days of starting he found that he has done only 25% work so to complete the remaining work on time by how much percentage he should increase his efficiency?
A) 12.5%
B) 15%
C) 10%
D) 20%
Option A
Solution:

Ashuâ€™s 1 dayâ€™s work …180/15 = 12 units
In 5 days he should have done …60 units
but he did……………….180/4 = 45 units
so remaining work = 135 units so complete it in 10 days he should do 135/10 = 13.5 units per day
therefore increased efficiency … 13.5 â€“ 12 = 1.5 >> 1.5*100/12 = 12.5%

1. Ambika

yes we ll make that also

2. ****

thanku mam :))

3. Destiny : Ultimate

Thankyou so much ðŸ™‚

4. poohhhhhh

total work 180 units kaise aaya

1. Ambika

LCM taken of no. of days taken by all

1. poohhhhhh

ok….thanx mam

2. poohhhhhh

mam mera total work unit 360 aa rha hai

1. Ambika

yaa u can take that

hi batman sir,…..:))

3. Alice

Q6
pulkit-9days
paras-9days
neha-24
ruhi-9
happy-24

ma’am 180 not 72?

1. Ambika

yess i have taken 180 ..72 is where ???

1. Alice

lcm of 9,9,24,9,24 = 72?

is the number of days taken by me are correct?

2. Ambika

yes yes its correct but u didn’t consider all the 12 people

3. Alice

okkk…its a single wrk completed by all of them. i took it as individual no. of days taken by all of them to do work individually..

4. Ambika

ohkk

5. Alice

thank you ma’am ðŸ™‚

6. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

yes it is single work .

7. Alice

yup..i interpreted it wrong

8. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

it happens sometime Dear .:

9. Alice

ðŸ™‚

2. Ambika

ohkk but 72 can’t be taken for 15 na …i have taken 180 for all including boys and girls

1. Alice

15?

2. Ambika

15 for ashu and 15 for hema too …72 can’t fit here na so 180 taken
u can take any number u want

3. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

it is correct dear ..where you get problem

4. Alice

got it knw..i understood ques wrong

5. Alice

yup this is where i gt stuck..wen 4 persons are working we take lcm of those 4 only why here everyone’s work in being taken into account?

but mod says its a single work done by all of them and the number of days is indicative of days individual person worked for those many days on the same work…not the individual person takes days to complete the whole work.

6. Ambika

no but if u take LCM of these 5 people as 72 then too the answer will come as 1/6
it won’t make any difference …it is my method of doing ques ..if u feel comfortable doing traditional method u can go for that too

7. Ambika

yes right :))

8. Alice

hope it helps everyone nw ðŸ™‚

9. Ambika

yess i ll keep in mind to give a more elucidated solution next time ðŸ™‚

10. AMAZON

@Alice thankyou dear

11. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

in 2 DI .first qo ,you should place an extra info ,qo looks more appropriate
If pulkit and paras started to work and after 2 days they were replaced by neha, ruhi and happy they were work for 2 days then they too stopped , how much work is still left ?

12. Ambika

yess it is like that only..typo

13. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

i know .the sense by which you made this qo but seems it looks improper,many are stuck on that point

14. Ambika

yes ðŸ™‚

15. Alice

no prblm ðŸ™‚

16. AMAZON

true

17. Ambika

yes it is edited now.. refresh the page once

18. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

Yup :

19. Alice

i got the same doubt

20. Ambika

u can take any LCM u want but answer will remain always the same

heeeheee…:)

22. Ambika

ðŸ™‚ how is that possible ??

??????

24. Ambika

see above

problm????

26. Ambika

if in question 1st ,if it is only asking about the 4 people pulkit paras neha ruhi happy
then in that case there is no need to find out the lcm of whole , right?
but problem is , answer is not coming same from both the cases, which is supposed to be same , isn’t?

6th que??

28. Ambika

hmm

29. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

qo is correct .

30. Ambika

yes it is but i think they r not getting the method ..

1/6 ans is comming?? whers the pblm

32. Ambika

what rearrangement ???

make work equal if not getting i think thats only otherwise its correct…..:))

——————–

35. Ambika

ohkk…but still answer will be same na
efficiency = 100/no. of days

yesss off course for better undestanding i meant to say i did it that way only now when i saw the comment then i checked the soln posted in that heheheheh….:)))

37. Ambika

:))

38. Alice

yup..its same..perfectly fine ðŸ™‚

39. Ambika

now everything clear ???

40. Alice

yes ma’am ðŸ™‚

it ws already wen u explained last time..i took it wrong

41. Ambika

no pblm ðŸ™‚
keep learning ðŸ™‚

42. Ambika

explain ur solution i ll check that

43. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

by LCM approach .without knowing the whole work how could you find out the their efficiency of per day,so it is necesry

3. Ambika

it means he has to complete whole work in the specified time only
he did 45 in 5 days but he was supposed to do 60 units so to compensate this 15 units’s deviation he will have to work more in next days to complete the work in time.

so remaining work = 135 and time 10 days so he should do 135/10 = 13.5 units per day now

and change is 13.5 – 12 = 1.5 and % = 1.5/12 *100 = 12.5

5. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

What is the total revenue generated if all the items produced in February are sold (assume MP to be SP here) ?
A) 945000
B) 994000
C) 995400
D) 954000
Option D
Solution :
revenue from pencils = 40*3 = 120
revenue from erasers = 35*2.4 = 84
revenue from markers = 70*9 = 630
revenue from scales = 35* 2 = 70
revenue from sharpeners= 30*1.5 = 45
TOTAL=949 INSTEAD OF total = 954
RE-CHECK QO NO 5/

1. poohhhhhh

949 ans aa rha hai mera

1. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

1. ??????????||ê€¸Îžà±®É¿Õ†É¿Ï‚||âˆšä¹‡åˆ€ã‚Šä¹‡ï½²ï½²ï¾‘â„¢

yes you can take 180 or 360 .both are correct here ,we take such value which is minimum possible value of that given no.

would you like to explain dear?
so remaining work = 135 units so complete it in 10 days he should do 135/10 = 13.5 units per day
therefore increased efficiency â€¦ 13.5 â€“ 12 = 1.5 >> 1.5*100/12 = 12.5%
Didn’t get this?

Ashu started working alone at his normal efficiency but after 5 days of starting he found that he has done only 25% work so to complete the remaining work on time by how much percentage he should increase his efficiency?
A) 12.5%
B) 15%
C) 10%
D) 20%

Ashuâ€™s 1 dayâ€™s work â€¦360/15 = 24 units
In 5 days he should have done=120 units
but he did 180/4 = 90 units
so remaining work = 270 units he has to complete it in 10 days
he should do 270/10 = 27 units per day
therefore increased efficiency â€¦27-24 ==3==3*100/24 = 12.5%

Let total work=LCM of All members=360
Pulkit 1 Day work=360/9=40
Paras 1 day work=360/9=40
2 day they work togeather=(40+40)*2=160

Neha 1 day work=360/24=15

1. SHAHU PAWAR

how do you get lcm 360 explanation please

1. Ambika

9……10………12…….15…….20……..24.. are the number of days taken by all
360 is assumed total work which is LCM of all these figures.

yess

2. _/_

how 100?

1. _/_

how 45?

2. Ambika

yes just 5 mint plz

3. Ambika

see i have taken the total work to be 180 units
so to get one day’s work we ll divide no. of days taken by a person by 180

so one day’s work of punit will be …..180/12 = 15 units
similarly we ll get …ashu’s 1 day’s work .. 12 units …………nikku’s work………..18 units
paras’s 1 day’s work ……………….20 units…..pulkit too ….20 units and …pradeep …15 units

adding all we get …20+20+15+15+12+18 we get 100
similarly for girls we ll get 45

yes jo normal time wo le rha hai usme hi complete karna hai

5 days me 60 karna tha na but hua kitna – 45 to remaining 10 days me wo 135 krega (180-45 ) = 135

1. _/_

abhi bhi ni aaya 10 days ?

1. Ambika

normal time kita leta wo 15 days na
first 5 days me usne total work (180) ka 25 % kiya means 45
left work = 135 and days left = 10 days (15-5 )

12. Diya

in ques 1st why we not take total cp = 56×2000 ??
