Dear Readers,

Today we are presenting the Data Interpretation questions set which is based on Bar Graph and Line Graph together in today's Quant Mania Session. Try It.

## Data Interpretation (Bar Graph & Line Graph)

**Directions (Q. 1-5): The bar graph shows the total number of children in five different school and the line graph shows the percentage of girls in them.**

**1. What is the approximate percentage of boys in School P and R together?**

a) 66%

b) 78%

c) 81%

d) 84%

e) 77%

**2. What is the total number of boys in School S and School T together?**

a) 3045

b) 3054

c) 3085

d) 3025

e) 3042

**3. What is the average number of boys in School R and School T together?**

a) 1612

b) 1625

c) 1675

d) 1655

e) 1635

**4. What is the ratio of the number of girls in School P to the number of boys in School T?**

a) 35:8

b) 6:35

c) 7:35

d) 35:3

e) None of these

**5. The number of boys in School T is approximately what per cent of the number of girls in School S?**

a) 778%

b) 775%

c) 730%

d) 788%

e) 745%

### Solution

**1. e**

Number
of boys in School P= 1500*(80/100) = 1200

Number
of boys in School R= 2000*(75/100) = 1500

Total
number of students in P & R together = 1500+2000 = 3500

So,
required % = (2700/3500)*100=77.14% = 77 (approx)

**2. d**

Total
number of boys in school S & T together is

= 1500*(85/100)
+2500*(70/100)

= 1275+1750

= 3026

**3. b**

Required
Average is

= ½[2000*(75/100)
+2500*(70/100)]

= ½[1500+1750]

= ½*3250

= 1625

**4. b**

Required
Ratio is

= 1500*(20/100):2500(70/100)

= 6:35

**5. a**

Number
of boys in School T = 2500*(70/100) = 1750

Number
of girls in School S = 1500*(15/100) = 225

Required
% = (1750/225)*100 = 777.77%= 778 (approx)
