Answer:

100 machines

Step-by-step explanation:

Vikas can buy 100 machines more if he gets a discount of rs 50 on each pumps

Solution:

Given that,

Vikas has enough money to buy 90 pumps worth Rs 500 each

cost of 1 pump = Rs 500

Find the cost of 90 pumps

Cost of 90 pumps = 90 x 500 = 45000

From given,

1 pump = Rs 50 discount

Therefore,

cost of 1 pump after discount = 500 - 50 = 450

Thus, with Rs 45000 , he can buy,

1 pump = Rs 450

"x" pumps = Rs 45000

By proportion,

x = 100

Thus, he can buy 100 machines more if he gets a discount of rs 50 on each pumps

Hope it will help you :)
