C.P of 40 balls = 50 per ball = 50*40 = 2000
S.P of 30 balls = 60 per ball = 60*30 = 1800
Gain to be made = 40%
S.P = C.P *(100+G)/100 = 2000*140/100 = 2800
Hence S.P for remaining(10 balls) = 2800 - 1800 = 1000
S.P of 1 ball = 1000/10 = 100
Hence remaining (10) balls should be sold at 100 per ball.
Hope it helps
S.P of 30 balls = 60 per ball = 60*30 = 1800
Gain to be made = 40%
S.P = C.P *(100+G)/100 = 2000*140/100 = 2800
Hence S.P for remaining(10 balls) = 2800 - 1800 = 1000
S.P of 1 ball = 1000/10 = 100
Hence remaining (10) balls should be sold at 100 per ball.
