Question

In a class of 56 students ,the number of of boys is 2/5th of the number of girls. Find the number of girls and boys.​

Answer 1

Answer:

Step-by-step explanation:Total number of student = 56

Let the number of Girls be = x

Then number of boys will be= 2/5 x.

According to question:-

x+2/5 x = 56

(5/5)x+ (2/5)x = 56 {by taking LCM}

(7/5)x = 56

7x = 56×5

x = 56×5/7

x = 8×5 {56 is divided by 7}

x = 40

So, number of girls = x

= 40

Number of boys = 2/5 × x

= 2/5 × 40

= 2 × 8

= 16

Hope it helps.
