Question 93

A person buys a car at 20%discount of the original price and sells it at 20% higherthan the original price. The percentage gain in this transaction iS

Solution

Let Original price of the car be Rs. 100

After 20% discount car's price = (100-20)/100 x Rs.100 = 0.8 x Rs. 100

= Rs. 80.

So CP for Man = Rs.80

Car was sold at 20% higher price,

So SP = (100+20)/100 x Rs. 100

= 1.2 x 100 = Rs. 120

SP for man = Rs. 120

Profit % = (SP-CP)/CP

=(120 - 80) / 80

= 50 % Answer
