Data Interpretation Practice Sets for SBI PO 2017, IBPS PO, NIACL, NICL, LIC, Dena Bank PO PGDBF, BOI, Bank of Baroda and other competitive exams

Directions (1 – 5): Study the following bar graphÂ carefully and answer the questions that follow:

1. If the cost price of P and T is equal to Rs 800 each. Find the difference in their Market Prices.
A) Rs 15
B) Rs 25
C) Rs 17
D) Rs 20
E) Rs 24
Option D
Solution:

P => Profit% = 30% = 3/10 [CP = 10, SP = 10+3 = 13]
Discount = 20% = 1/5 [MP = 5, SP = 5-1 = 4]
Make SP same
CP : SP : MP is
40 : 52 : 65 â€¦â€¦â€¦â€¦â€¦â€¦(1)
Now T =>Profit% = 40% = 4/10 [CP = 10, SP = 10+4 = 14]
Discount = 12.5% = 1/7 [MP = 8, SP = 8-1 = 7]
Make SP same
CP : SP : MP is
10 : 14 : 16â€¦â€¦â€¦â€¦â€¦â€¦.(2)
Make CP of P and T same by multiplying eq. (2) by 4, gives
CP : SP : MP is
40 : 56 : 64
So 40 = 800 [as given in question]
=> 1 = 20
Difference in MP = 65-64 = 1, so => 1 = 20 is answer
2. If the market price of S is 200% of market price of R, then find the selling price of R, if market price of S is Rs 3600.
A) Rs 1200
B) Rs 1300
C) Rs 1150
D) Rs 1400
E) Rs 1050
Option A
Solution:

For S:
CPâ€¦.SPâ€¦..MP is 4â€¦â€¦..5â€¦â€¦â€¦6 â€¦â€¦â€¦â€¦â€¦â€¦â€¦..(1)
For R:
CPâ€¦.SPâ€¦..MP is 5â€¦â€¦..6â€¦â€¦â€¦9 â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦(2)
Mp of S is 200% of R
200% of 9 = 18
Multiply eq. (1) by 3
CPâ€¦â€¦â€¦SPâ€¦â€¦â€¦MP is 12â€¦â€¦15â€¦â€¦â€¦..18
Now 18 = 3600
1 = 200
6 = 1200 – Answer
3. Find the ratio of selling price of S and R if the cost price of both is same.
A) 24 : 29
B) 23 : 22
C) 25 : 24
D) 23 : 20
E) 23 : 25
Option C
Solution:

For S:
CPâ€¦..SPâ€¦..MP is 4 â€¦â€¦..5â€¦â€¦â€¦.6 â€¦â€¦â€¦â€¦â€¦â€¦â€¦(1)
For R:
CPâ€¦..SPâ€¦..MP is 5 â€¦â€¦..6â€¦â€¦â€¦.9 â€¦â€¦â€¦â€¦â€¦â€¦â€¦(2)
Multiply eq. (1) by 5 and (2) by 4
(1) gives.,, 20â€¦â€¦â€¦..25â€¦â€¦â€¦..30
(2) gives,, 20â€¦â€¦â€¦..24â€¦..â€¦…36
SP of S : R is 25 : 24
4. Find the selling price of Q if the ratio of market price of Q and S is 5 : 1 and the cost price of S is Rs 4000.
A) Rs 15,000
B) Rs 21,000
C) Rs 18,000
D) Rs 23,000
E) Rs 14,000
Option B
Solution:

For S:
CPâ€¦..SPâ€¦..MP is 4 â€¦â€¦..5â€¦â€¦â€¦.6 â€¦â€¦â€¦â€¦â€¦â€¦â€¦(1)
For Q:
CPâ€¦..SPâ€¦..MP is 14 â€¦â€¦..21â€¦â€¦â€¦.30 â€¦â€¦â€¦â€¦â€¦â€¦â€¦(2)
Here already ratio of MP of Q : S is 5 : 1
So,
4 == 4000
1 == 1000
SP of Q = 21 == 21000
5. If the cost price of R and P is same, then find how much % the selling price of P is more or less than that of R.
A) 10 2/3%
B) 9 1/4%
C) 5 2/5%
D) 8 1/3%
E) None of these
Option D
Solution:

For R:
CPâ€¦..SPâ€¦..MP is 5 â€¦â€¦..6â€¦â€¦â€¦.9 â€¦â€¦â€¦â€¦â€¦â€¦â€¦(1)
For P:
CPâ€¦..SPâ€¦..MP is 40 â€¦â€¦..52â€¦â€¦â€¦.66 â€¦â€¦â€¦â€¦â€¦â€¦â€¦(2)
To make CP same, multiply (1) by 8
(1) gives CPâ€¦..SPâ€¦..MP is 40 â€¦â€¦..48â€¦â€¦â€¦.72
SP of P is 4 more than that of R
So 4/28 * 100 = 8 1/3% more

Directions (6 – 10): Study the following pie-charts carefully and answer the questions that follow:

1. If the incomes of company A and B are in the ratio 2 : 3 and the income of company B is 120% of its expenditure, then what is the difference between the income of company B and the income of company A?
A) Rs 50 lakh
B) Rs 40 lakh
C) Rs 60 lakh
D) Rs 55 lakh
E) None of these
Option B
Solution:

Expenditure of Company B = 100 lakh
Income of Company B = 120/100 * 100 lakh = 120 lakh
Income of Company A = 2/3 * 120 lakh = 80 lakh
Required difference = 120 â€“ 80 = 40 lakh
2. If the number of employees in Company A is 1120 then what is the average salary of the employees in Company A?
A) Rs 4500
B) Rs 4000
C) Rs 2500
D) Rs 2000
E) Rs 3000
Option D
Solution:

Total expenditure on the employees of company A = 28/100 * 80 lakh = 22.4 lakh
So average salary of employees = 2240000/1120 = Rs 2000
3. What is the ratio of tax paid by Company A to that by Company B ?
A) 30 : 13
B) 28 : 15
C) 25 : 11
D) 27 : 11
E) 30 : 17
Option B
Solution:

The required ratio is
14/100 * 80 lakh : 6/100 * 100 lakh = 28 : 15
4. What is the difference between the expenditure on employees of Company B and that of Company A?
A) Rs 116000
B) Rs 116 lakh
C) Rs 123 lakh
D) Rs 11.6 lakh
E) Rs 12.3 lakh
Option D
Solution:

Required difference = 34/100 * 100 lakh â€“ 28/100 * 80 lakh = 11.6 lakh
5. The expenditure on Machinery of Company B is what per cent more than that on the same item of Company A?
A) 86.5%
B) 83.5%
C) 87.5%
D) 85.5%
E) 82.5%
Option C
Solution:

Expenditure on Machinery of Company B = 18/100 100 lakh = 18 lakh
Expenditure on Machinery of Company A = 12/100 * 80 lakh = 9.6 lakh
So Required % = (18 lakh â€“ 9.6 lakh)/9.6 lakh * 100 = 87.5%

1. MiMi

Thnk u mam 6-10 done..but 1st di samaj me nhi aya..diagram me p,q,r,s mention nhi kiya..

2. AntiVirus

mam cp:sp:mp = 40:52:65 kese hua

1. We have to make SP same. Multiply eq 1 by 4 and eq 2 by 13.
So CP from 1 is 10Ã—4
SP is 4Ã—13 or 13Ã—4.
And MP from eq. 2 is 5Ã—13

5. sachin shukla@ my turn 2017

ty.

mam ratio smj ni aaya sp mp cp kaaaa….:(

1. In which q ??
U have to multiply to get CP same. Or SP same. As required

Mam… But ratio kaise aa rha h…means jo prcnt vlu h usko ratio mn cnvrt ki… ? I didn’t get that method mam… ? ðŸ™‚

1. Hehe. Ok ok

See discount% – discount/MP se ata hai.
So agar discount % = 1/5
To 5 MP ho gai and 1 discount ho gya.
Next SP = MP – discount to 5 – 1 = 4.
Same profit % ya loss% k case me hoga

Yaa mam… I thought that process first mam…But then no need of given values…. ????

P => Profit% = 30% = 3/10 [CP = 10, SP = 10+3 = 13]
Discount = 20% = 1/5 [MP = 5, SP = 5-1 = 4]
Make SP same
CP : SP : MP is
40 : 52 : 65 â€¦â€¦â€¦â€¦â€¦â€¦(1)
this step mp isme uper niche dono pe multiply kia h mam…:)

3. SP same karni hai na.
To dono me karna pdega.
Like linear equations solve karte hai na
Coefficients same bna k

mam tb to aur b easy ho gya becoz fr values jo di h uski use nhi krni padegi becoz percent values se sbi k ans aa jasyega…:)
