If the expenditure increased by 20% in 2017 compared to 2016, and the profit percentage in 2016 was 25% less than the profit percentage in 2017, then what is the income of the company in 2016 (in rupees million)?
The 2016 income is 84.2025, so the answer is 84.2025.
The 2017 expenditure is 92.7, and it is 20% more than the 2016 expenditure.
So the 2016 expenditure is 92.7 divided by 1.20, which is 77.25.
The 2017 profit is 12%, and the 2016 profit is 25% less, which is 9%.
So the 2016 income is expenditure plus 9% of it.
That is 77.25 plus 9% of 77.25, which is 77.25 plus 6.9525.
This equals 84.2025.
