Question

A man bought some bananas of Rupees 4 at the rate of 10 and sold them for rupees 4 at rate of 8 What will be Profit or loss percentage?​

Answer 1

Answer:

Purchase cost per banana=10/6=5/3 and sold at 6/4=3/2 hence loss per banana is 5/3–3/2=10–9/6=1/6 Rs hence loss % is ((1/6)/(5/3))*100= 3*100/30=10%

Answer 2

CP of 1 banana = 6 10

Rs.=1.667Rs.

SP of 4 banana =6Rs.

SP of 1 banana = 4 6

Rs.=1.5Rs.

Since CP of 1 banana greater than SP of 1 banana.

Therefore,

Loss%= CP

CP−SP×100

= 1.667

1.667−1.5 ×100=10%
