Question

In a class of 40 pupils. Girls are given 5 lollipops and boys are given 2 lollipops. How many girl's are in the class.

Answer 1

Answer: 15

Step-by-step explanation: Let x be the no. of boys in the class. The the no. of girls are x*3/5. Now, it's given that the no. of pupils is 40. So,

x+ (3/5)*x=40

=> x*(8/5)=40

=> x= 40*5/8

=> x= 25.

Ans: The no. of boys in the class is 25, so there must be 15 girls .-.
