Question

A shopkeeper bought 40 cricket balls at the rate of 50 per ball. He sold 30 balls at
the rate of 60 per ball. At what rate per ball should he sell the remaining balls to gain
40% in the whole transaction?
​

Answer 1

Answer:

100

Step-by-step explanation:

cost prize = 40*50 = 2000

money gained after = 30*60 = 1800

selling 30 balls

sale prize for 40% gain,

= 2000 + 2000*40

100

= 2000 + 800

= 2800

money he still needs to earn

= 2800-1800

= 1000

1000 for 10 balls, so each ball should be sold at Rs 100
