Answer :

Solution :

From the figure, the revenue of company Q in 2015 = 45 million rupees

Given that the revenue of company Q in 2015 was 20% more than that in 2014

The revenue of company Q in 2015 = 1.2 times the revenue of company Q in 2014

⇒ The revenue of company Q in 2014 = 45/1.2 = 37.5 million rupees

Given that the company Q had earned a profit of 10% on expenditure in 2014 % of profit = ((revenue – expenditure)/expenditure) × 100

Let the expenditure in 2014 is ‘x’ million rupees

$\Rightarrow 10=\frac{37.5-x}{x}\times 100$

⇒ 1.1 x = 37.5

⇒ x = 34.09 ≈ 34.1 million rupees
