Question

A quantity of tea is sold at Rs. 5.75 per kilogram. The total gain by selling the tea at this rate is Rs. 60. Find the quantity of tea being sold if a profit of 15% is made on the deal ?

Answer 1

Say total cost price of tea is $x$.
Then total profit at a rate of $15\%$ is $=\left(\frac{15x}{100}\right)$
According to question,
$\frac{15x}{100}=60$
so$x=400$
C.P of the tea is Rs.$400$.
so total selling price will be $=(400+60)=$ Rs.$460$
so the quantity of the tea will be $=\left(\frac{460}{5.75}\right)=80$kg.
