Expert Answer

Question must be:

if this is a ball and a bat that cost 100 ruppe but the bat cost 10 ruppe more than that of a ball, what is the total cost of ball and bat ?

Solution:

Let x and y be the costs of ball and bat respectively.

As per the condition, we have

x + y = 100

Since, y = 10 + x

Therefore, 2x + 10 = 100

2x = 90

x = 45

Cost of ball is rs 45 and that of bat is rs 55.
