Question

In a class, the number of boys is more than the number of girls by 12% o the total students. What is the
ratio of number of boys to that of girls?​

Answer 1

Answer:

14 : 11

Step-by-step explanation:

Let the number of students in the class be 100

Therefore, 12% of the total students = 12/100 * 100

= 12 students

Let number of girls in the class be x

Therefore, number of boys = Number of girls + 12% of students in the class

Therefore, number of boys = x + 12

Also, number of girls + number of boys = Total number of students in the class.

So,

x + (x + 12) = 100

∴ 2x + 12 = 100

∴ 2x = 88

∴ x = 44

Therefore,

number of boys = x + 12

= 56 boys

Therefore,

Number of Boys : Number of girls

= 56 : 44

= 28 : 22

Ans = 14 : 11
