Question

Rahul brought a hockey and a ball for 110 rupees. If the cost of the hockey is 100 rupees more than the cost of ball,rhen what is the cost of the ball?

Answer 1

let cost of ball = x
then cost of hockey = 100 + x
according to question,
x +(100+x) = 110
2x +100= 110
2x = 10
x=5 , which is cost of the ball
