Correct Answer - Option 3 : 50 paise
Given:
Price of banana decreased = 20%
5 bananas more can be purchased in = Rs. 10
Calculation:
Let the CP of each banana be x
Total number of banana in Rs. 10 = 10/x
New price = x – (20/100) × x = 80x/100 = 4x/5
New number of bananas in Rs. 10 = 10/(4x/5) = 25/2x
⇒ (25/2x) – (10/x) = 5
⇒ 10x = 5
⇒ x = 5/10
⇒ x = 1/2
⇒ 50 paise
∴ The initial price of one banana is 50 paise
