A machine costs ₹ 7500. Its value decreases by 5% every year due to usage. What will be its price after one year?

The cost price of the machine = ₹7500

Decrease in price = 5%

Decreased price after one year:

= 7500 (1 − 5/100) = 7500 × (95/100)

= 75 × 95

= ₹7125

Hence, the required price = ₹7125.
