Akhil bought 13 kg of apples for Rs 2,400. He sold them at profit equal to the selling price of 7 kg of apples. Find the selling price of apples per kg.
Answer & explanation
Correct answer: option 1
The cost price of the apples per kg = $\frac{2400}{13}$ = CP
Let the selling price per kg = SP
According to the question,
Profit = 7SP
We know, profit = SP - CP
⇒ 7SP = 13SP - 13CP
⇒ 6SP = 13SP
⇒ SP = 13/6 CP
we substitute the value of CP,
⇒ SP = $\frac{13}{6}$ x \(\frac{2400}{13}\)
= Rs 400
