Question

6 bananas were bought for rs 5 and sold at 5 for rs 6.what is the gain?

Answer 1

31 by 6 is the answer

Answer 2

hi Kamal,

Let cost per banana = b

so

CP
6b = 5
b = 5/6
CP of 1 banana = 5/6 Rs
Total CP of 6 bananas = 5/6 * 6 = 5 Rs

SP
5b = 6
b = 6/5
SP of 1 banana = 6/5 Rs
Total SP of 6 bananas = 6/5 * 6 = 36/5 Rs

Gain = SP - CP
= 36/5 - 5
= 11/5
= 2.20 Rs

so the gain is Rs 2.2

Hope it helped.
Let me know if any doubts.
Cheers !!!
