MCQ
Solution
₹ 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
