Question

The ratio of the numbers of boys to that if girls in a class is 4:9, if the number of boys is 32 , find the number of girls in the party

Answer 1

Answer: 72

Step-by-step explanation:

Let the number of boys be 4x

And number of girls be 9x

But the actual strength of boys is 32

So, 4x must be equal to 32

4x= 32

x = 32/4

x= 8

Now putting the value of x in 9x

9X 8

72

So, the number s of girls is 72.

Answer 2

Solutions :-


Given :
The ratio of the numbers of boys to girls in a class is = 4 : 9
Number of boys = 32

Let the number of girls be x


A/q

=> 4/9 = 32/x
=> 4 × x = 32 × 9
=> 4x = 288
=> x = 288/4 = 72



Hence,
The number of girls in the class = 72
