Question 51

A study was made for the number of persons of different age group visited in a library in a week which is shown in the histogram. Study the histogram and answer the question given below.

The ratio of the number of persons in the age groups 15-20 years and 20-25 years together, to the number of persons in the age groups 30-35 years and 35-40 years together, is:

Solution

From the histogram,

Number of persons in the age groups 15-20 years and 20-25 years together = 300 + 400 = 700

Number of persons in the age groups 30-35 years and 35-40 years together = 350 + 100 = 450

$$\therefore\ $$Required ratio = 700 : 450 = 14 : 9

Hence, the correct answer is Option A
