Answer : 1. "20%"
Explanation :

Answer: A) 20% Explanation: Suppose that the original price of the car = Rs. x  Then new price of the car => (x) + (x ×25/100) = Rs. 5x/4  To restore the original price, the new price must be decreased by 5x/4 − x = x/4 So required percentage =(x/4)/(5x/4) × 100% = 20%
