Keshav gets a 4% increase in his sale amount in the first year and a 20% increase in the second year, and with that his present sale is ₹1,56,000. What was his sale (in ₹) two years ago?​

Correct option is A

Given:

1st year increase = 4%

2nd year increase = 20%

Present sale = ₹1,56,000

Solution:

Let the original sale 2 years ago be ₹x 

​$$x \times (1 + \frac{4}{100}) \times (1 + \frac{20}{100}) = 156000$$​​

​$$x \times 1.04 \times 1.20 = 156000$$​​

​$$x \times 1.248 = 156000$$​​

x = $$\frac{156000}{1.248}$$​ = ₹1,25,000
