विकल्प

• ₹ 22,00,000

• ₹ 25,00,000

• ₹ 20,20,000

• ₹ 20,00,000

Answer 1

₹ 20,00,000

Explanation:

Let the income of the company in 2015 = 16 unit

Then, 25% increases each year

So, income in 2016 = `16 + 1/4 xx 16`

= 20 unit

Income in 2017 = `20 + 1/4 xx 20`

= 25 unit

Now, 25 unit = 31,25,000

∴ 16 unit = `(31,25,000)/25 xx 16`

= 1,25,000 × 16

= 20,00,000

∴ The income in 2015 = ₹ 20,00,000
