Question

A man buys 6 dozen oranges for Rs. 10.80.12 oranges are found rotten and the rest are sold at
five for a rupee. Find its gain or loss per cent.​

Answer 1

Step-by-step explanation:A man buy 6 dozen oranges for Rs. 10.80. In which 12 oranges are found rotten.

12 oranges are rotten means, 1 dozen organes are rotten.

(As 1 dozen orange = 12 orange)

So,

Remaining orange = 5 dozen

=> 5 × 12 = 60 oranges

It is also said in question that remaining oranges are sold at five for one rupee.

Selling price of 1 orange = Rs. 1/5

And we have remaining oranges = 60

So, selling price of 60 oranges = Rs. 1/5 × 60

=> Rs. 12

So,

Profit of man = 12 - 10.80

=> Rs. 1.2

According to question, we have to find the profit or loss percent of the man.

So,

Profit % = Profit/Cost price × 100

=> 1.2/10.80 × 100

=> 0.1111 × 100

=> 11.11%

∴ The man gain 11.11%
