Correct Answer - Option 1 : 15%
GIVEN:
Saral bought apples for rupees 300. She sold 1/3rd of it at 30% loss.
CONCEPT:
Basic concept of Profit and Loss.
FORMULA USED:
SP = CP × [1 + Profit/100]
SP = CP × [1 – Loss/100]
CALCULATION:
According to the question 1/3rd apples are sold at 30% loss.
Therefore,
Selling price of 1/3rd of the apples = (300/3) × (1 – 30/100) = 100 × (70/100) = Rs. 70
Now the 2/3rd apples have to be sold at a profit p% such that there is no profit or loss overall. That is:
Selling price of 1/3rd apples + Selling price of 2/3rd apples = 300
Hence,
70 + (300) × 2/3 × (1 + p/100) = 300
⇒ 1 + p/100 = 230/200
⇒ p/100 = 3/20
⇒ p = 15%
∴ The required percentage is 15%.
