Answer:
100
Step-by-step explanation:
Correct option is
A
100
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.
