Question

A man bought 80 mangoes at Rs I each. 10 of them could not be sold as they got rotten.
He sold the remaining at Rs 1.50 each. What was his profit or loss?​

Answer 1

80 mangoes for 80 rupees =cost price

out of 80 , 70 were sold at rupees 1.5 each

thus , 70*1.5 =105=selling price

profit =105-80 =25

thus , there was a profit of 25 rupees
