Study the following bar graph and answer the questions given below:
The number of boys in school B is what percentage of the total number of students in that school?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 60%
Total number of boys and girls in school B = 2600
a + b = 2600 ( where a = number of boys and b = number of girls).......(1)
The difference in the number of boys and girls in school B = 520
a - b = 520.......(2)
From 1 and 2 we get,
a = 1560.
The total number of students in the school B = 2600
Required % = 1560/2600 × 100 = 60%.
