Question

By selling 45 lemons for rs 40, a man loses 20 %. how many should he sell for rs 24 to gain 20 % in the transaction ?

Answer 1

Explanation:
Let S.P. of 45 lemons be Rs. x.

Then, 80 : 40 = 120 : x or x =
40×120
80

= 60

For Rs.60, lemons sold = 45

For Rs.24, lemons sold =
45
60

×24= 18.
