Question

Raghu has enough money to buy 75 machines worth Rs. 200 each. How many machines can he buy if he gets a discount of Rs. 50 on each machine?

Answer 1

Let number of machines be ‘x’ machines

When cost of one machine decreases = 200 – 50 = 150Rs

| Cost (Rs) | 200 | 150 |
| No. of machines | 75 | x |

We know k = xy

200 × 75 = 150 × x

x = (200×75)/150

= 100

∴ Raghu can buy 100 machines when he gets a discount of Rs 50 on each machine.
