Question

A person bought some eggs at four a rupee. He kept one-fifth of them, and sold the rest at three a rupee, and gained one rupee. How many eggs did he buy?

Answer 1

Step-by-step explanation:

Let the number of eggs bought by the person be x

therefore, Money spent=x/4

he kept x/5 with him therefore remaining eggs:

x-x/5=4x/5, which he sold at 3 rupees

that is 4x/(3*5)=4x/15

given profit is 1 rupee that is,

4x/15-x/4=1

(16-15x)/60=1

x/60=1

x=60

Therefor, number of eggs bought is 60.

I hope this helps.

All the best
