# Quantitative Aptitude: Data Interpretation Questions Set 48

Directions(1-5): Study the following table carefully to answer the questions. The table given the percentage of marks obtained by six students in six different subjects. Here, P, Q, R, S, T, U are the six different subjects. 1. What is the average percentage of marks obtained by all the students in subject ‘P’?
A) 72(1/3)
B) 72(1/2)
C)78(1/5)
D)77(1/4)
E) 77(1/5)
Option A
Solution:
Required average % = (80+55+74+68+75+82)/6 = 72(1/3)
2. What is the overall percentage of marks obtained by B in all the subjects?
A) 70%
B) 78%
C) 72%
D) 88%
E) 82%
Option C
Solution:
Required % = (55 + 70 + 67 + 74 + 88 + 78)/6 = 72%
3. What are the total marks obtained by all the students together in subject T ?
A)  527
B) 625
C)600
D)534
E) 550
Option D
Solution:
Total marks obtained = 90 + 105.6 + 74.4 + 86.4 + 96 + 81.6  = 534
4. What are the average marks obtained by all the students in subject ‘R’ (approx.)?
A)  60
B) 56
C) 50
D) 64
E) 78
Option B
Solution:

5. What are the total marks obtained by student C in subjects Q, S and T ?
A)  130
B) 140
C) 138
D) 155
E) 145
Option C
Solution:
Marks obtained by C in subject Q = 54*(40/100) = 21.6
subject S = 84*(50/100) = 42
subject T = 62*(120/100) = 74.4
Therefore ,required total marks = 21.6 + 42+ 74.4 = 138

Directions(6-10): Study the table carefully and answer the questions that follow:

Description of Literate and Illiterate population of six villages. 1. The number of literate women in village B is 39760 and that of illiterate women in village C is 25600. By what percent is the population of village B is less that that of village C?
A)  13.07
B) 13.25
C)10.10
D) 11.25
E) 21.5
Option D
Solution:
Literate men in village B = (8/7)*39760 = 45440
Literate males and females = 45440 + 39760 = 85200
If 60% ==== 85200
then 100% ==== (85200/60)*100 = 142000
Illiterate males in village C = (3/4)*25600 = 19200
Illiterate population = 25600 + 19200 = 44800
If 28% ====44800
then 100%====(44800/28)*100 = 160000
Therefore ,required % = (160000 – 142000)*100/160000 = 11.25
2. If the number of literate women in village D is 32200, what is the number of illiterate population in the same village ?
A)  48575
B) 57042
C)45000
D) 54050
E) 48300
Option E
Solution:
Literate males in village D = (5/4)*32200 = 40250
Total literates = 32200 + 40250 = 72450
60%====72450
40%====(72450*40)/60 = 48300
3. If the population of village F is 168000, what is the number of literate males ?
A)76800
B) 67200
C)45072
D) 57480
E) 65770
Option B
Solution:
Literate population in village F = (168000*64)/100 = 107520
Number of literate males = (5/8)*107520 = 67200
4. If the illiterate female population of village E be 77000, what is the total population of that village ?
A)  257850
B) 331250
C) 350000
D) 425600
E) 324560
Option C
Solution:
Illiterate males in village E = (14/11)*77000 = 98000
Total illiterate = 77000 + 98000 = 175000
Therefore ,total population = 2 *175000 = 350000
5. If the number of literate males in village A be 35840, the number of illiterate males in the same village ?
A)  45022
B) 43264
C) 41500
D) 40000
E) 42781
Option B
Solution:
Literate females in village A =(5/7)*35840 = 25600
Total literate population = 25600 + 35840 = 61440
48% ====61440
52%====(61440/48)*52 = 66560
Illiterate males = (13/20)*66560 = 43264

I have been following you for quite some time and I must say that you have very good grip on quants, your explanations are always very lucid. Could you please share an approach regarding Quants section for Ibps po mains 2017, this new pattern (sbi po mains 2017) troubled me a lot 🙁

3. Eng m AweSomE

2nd DI
3q
16800*64/100*5/8*7/12 =39200
crt me if i wrg

1. \$קгค๔єєק\$

100 =64(l) & 36(i)
64 =40(ml) &24(wl)
now 100 =168000
=> 40 =literate male =67200
option 2

2. \$קгค๔єєק\$

ist ratio of male and female is itself the literate male and female ratio..:)

3. Banya

Total Literate population in village F = (168000*64)/100 = 107520
Number of literate males in village F= (5/8)*107520 = 67200

Maam/Sir ,
will ibps 2017 be fully based on sbi mains 2017? or we can expect these kinds of DI’s too in the exam? because sbi mains was full of DI based on miscellaneous chapters. pls reply sbi mains troubled me a lot .. 🙁 🙁

1. Shubhra

It cannot be said that whether IBPS would be fully based on SBI

Last year it was, but cannot be said for sure
So keep practicing such questions
But yes this is for sure that IBPS PO will have DIs based on chapters, all DIs or some – cannot be said

1. Navya

mam, Mains mai chapter based DI ayegi but pre mai to calculative k hi chances hain na..;(

1. Shubhra

yes pre me calculative

but vo itne b calculative nhi hote

like in 1 DI, we will have 5 questions, so 10 questions in 2 DIs
from those 10 questions, you will be able to solve 7-8 very easily. Need not solve all 5 in 1 DI, leave the one in which much calculation – thats it. very simple way to crack pre
