Question

R2. The no. of boys and girls in a class
are in the ratio 5:4, If the no.
of boys is 9 more than no. of girls
find no. of girls and boys.​

Answer 1

Answer:

Let the no. of boys be 5x and no. of girls be 4x

given 5x - 4x= 9

x=9

therefore no. of boys = 9X5 = 45

Answer 2

Answer:

Let the no. of boys and girls be 5x and 4x respectively.

No. of boys is 9 more than the girls

This means that the difference between no. of boys and no. of girls is 9

Therefore,

5x - 4x = 9

x = 9

Therefore the no. of girls = (4×9)= 36

no. of boys =( 5×9)=45
