Question

Rakesh has enough money to buy 90 lamps worth 500 each. How many more lamp can he buy if,
he gets a discount of 50 on each lamp inverse variation
​

Answer 1

Step-by-step explanation:

Cost of each pump = Rs.500

So cost of 90 pump = 90×500 = Rs.45000

So total money that Vikash had = Rs.45000

Discount on each pump = Rs.50

So cost of each pump after discount = Rs.500 - Rs.50 = Rs.450

So, number of pumps in Rs.45000 = 45000450 = 10

Therefore Vikash can buy 10 pumps.
