The current price of a laptop is ₹78,000 after a 20% increase this year. What was the price of the laptop last year?

Correct option is C

Given:

Current Price = ₹78,000

Increase = 20%

Formula Used: 

If a number is increased by x%, then

New Price = $$\text{Old Price} \times \left(1 + \frac{x}{100}\right)$$​​

Solution:

Old Price = $$\frac{\text{New Price}}{1 + \frac{x}{100}}$$​

​$$= \frac{78000}{1.20}$$​​

= ₹65,000
