Question

raghu has enough money to buy 75 machines worth rs 200 each. how many machines can he buy if he get a discount of rs 50 on each machine​

Answer 1

Let x be the number of machines he can buy if a discount of Rs.50 is offered on each machine.

Number of machines 75 x

Price of each machine ( in Rs ) 200 150

Since, Raghu is getting a discount of Rs.50 on each machine, the cost of each machine will get decreased by Rs.50

If the price of a machine is less, he can buy more number of machines.

It is a case of inverse variation.

∴ 75×200=x×150

⇒ x=

150

75×200

⇒ x=

150

15000

⇒ x=100

∴ The number of machines ha can buy is 100.
