Answer 2

Answer:

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=15075×200

⇒  x=15015000

⇒ x=100

∴  The number of machines ha can buy is 100.
