Correct Answer - Option 1 : 16
Given:
The cost price of 20 bananas is the same as the selling price of x bananas
Profit = 25%
Formula:
Profit % = (Profit/CP) × 100
Calculation:
Let Cost Price of each banana be Rs. 1
Cost Price of x bananas = Rs. x
Selling Price of x bananas = Rs. 20
Profit = Rs. (20 - x)
⇒[(20−x)/x] × 100 = 25
⇒2000 − 100x = 25x
⇒ 125x = 2000
⇒ x = 16
∴ The value of x is 16
