Question 85

A trader buys jowar at Rs 30 per kg. 20% of the grain gets wasted. He plans to sell the remaining grain so that he makes 40% overall profit. At what price (in Rs per kg) should he sell the grain?

Solution

Let say, total jowar is 100 kg and he sold rest of jowar in x Rs/kg.

Iotal cost price of 100 kg =$$100\times30=3000\ Rs.$$

Wasted grain = $$100\times0.20=20\ kg.$$

So, He sold 80 kg at the price of x Rs/kg to gain 40% overall.

So, according to question,

$$80x-3000=0.40\times3000\ .$$

or, $$x=1.40\times\frac{3000}{80}=52.50\ .$$

So, C is correct choice.
