# The price of a car is increased by 25%, by how much percent, must the new price of this car be decreased to restore its original price ?

 A) 20% B) 24% C) 21% D) 25%

 A) Rs. 87400 B) Rs. 68700 C) Rs. 74000 D) Rs. 94060

72p = 62928 x 100

p = 62928 x 100/72

p = 87400

Hence, the total amount he had = p = Rs. 87400.
