Question

A man buys lemons at 6 for Rs 10 and sells at 8 for Rs 15 . Find the gain per cent

Answer 1

He bought 6 lemons at thecist of 10 .
first, find the cost of 1 lemon .
so, 6. = 10
1= 10/6 = 5/3

Second is 8 lemon on 15 rupees.
1= 15/8

so his gain percent is (15/8×100)/5/3
15/8×100×3/5
12.5 %he gain

Answer 2

A man buys lemons at 6 for Rs 10

∴CP of 1 lemon  = Rs 10/6

∴CP of 8 lemons = Rs 10/6 *8 = Rs 13.33

Now

SP CP of 8 lemons = Rs 15

∴Profit = [Rs 15 - 13.33] = Rs 1.67

∴Profit %  = profit / CP * 100

∴Profit %  = 1.67 /  13.33 * 100  =12.5 % ANS
