Answer 1

boys who play cards only and boys who play carrom only

Step-by-step explanation:

Let's the x boys who play both cards and carom.

 Boys who only play cards = 45-x

Boys who only play Carrom = 30-x

Boys who play both = x

 the total number of boys in the class=60

(45-x) + (30-x) +x=60

75-x=60

x=15

Boys who only play cards=45-x=45–15=30

Boys who play Carrom=30-x=30-15=15
