Question

Rashmi purchased 50 bananas for ₹150. She could not sell five of them as they were rotten. At what price should Rashmi sell each of the remaining bananas in order to make a profit of 20%?

• A. ₹ 2
• B. ₹ 3
• C. ₹ 4
• D. ₹ 5

Answer 1

The correct option is C ₹ 4

Cost of 50 bananas = ₹150

Remaining bananas to be sold = 50 - 5 = 45

In order to make a profit of 20%,

Selling price = Cost price + (20% of Cost price)

$\Rightarrow$ Selling price = ₹150 + (20% of ₹150)

$\Rightarrow$ Selling price = ₹150 + $(\frac{20}{100}\times ₹150)$

$\Rightarrow$ Selling price = ₹150 + ₹30 = ₹180

Now, selling price of 45 bananas should be ₹180.

$\Rightarrow$ Selling price of each banana should be $\frac{180}{45}$ = ₹4.
