Abought a car for rs.1 and spent rs. 1 on its repairs. he sold this car to b at a gain of 10% who later on sold to close at a gain of 5%.what did c pay for the car?

C paid Rs.127050 for the car

Solution

Price of car of A = Rs.100000

A spent Rs. 10000 on its repairs

Cost price of car of A = Rs.100000 + Rs. 10000 = Rs. 110000

He sold this car to B at a gain of 10 %

gain = 10 %

Selling price of car = cost price + gain %

Selling price of car = 110000 + 10 % of 110000

Thus selling price is Rs. 121000

Therefore, cost price of car purchased by B = Rs. 121000

B sold the car to C for 5 %

Gain = 5 %

selling price of car = Rs. 121000 + 5 % of Rs. 121000

Thus C paid Rs.127050 for the car

both equations and proportions are better.
