Ashis purchases eggs at the rate of Rs 90 for 150 eggs and sells them at Rs 85 per hundred. Find his gain or loss per cent.

Pls pls help***

Answer 1

let r be the rate of increase
8(1) = 6(1+r)
8 = 6 + 6r
6r = 2
r = 1/3 or 33 1/3%

purchase price = 90/150 = .6 per egg
selling price = 85/100 = .85 per egg

percentage gain = .25/.6 = .41666... or 41 2/3%
