Correct Answer - Option 1 : Rs.40
Given
A man sells 20 bananas at Rs.600
He bears a loss equal to cost price of 5 bananas.
Formula used
CP(1 - L/100) = SP
CP = Cost Price
SP = Selling Price
L = Loss
Calculation
Let cost price of 1 banana be Rs.x
⇒ Cost of 20 bananas = Rs.20x
⇒ Loss = 5x
⇒ 20x - 5x = 600
⇒ 15x = 600
∴ Cost price of 1 banana is 40
