A man bought banana at the rate of rs. 10 for rs. 45 and sold at the rate of one dozen banana for rs. 51 . Find his gain or lost %
Hello,
Cost of 10 bananas = Rs. 45
Cost of 1 banana = 45/10
= Rs. 4.5
Selling price of 12 bananas = Rs. 51
Selling price of 1 banana = 51/12
= Rs. 4.25
Loss = Cost price of 1 banana - Selling price of 1 banana
Loss = 4.5 - 4.25
Loss = Rs. 0.25
Loss percent = (Loss*100)/Cost price
⇒ (0.25*100)/4.5
⇒ 25/4.5
⇒ 5.55%
So, he suffered a loss of 5.55 %.
