If the income of Company Y in 2018 was Rs. 600 crores, what was its expenditure in that year?

Answer: B

Profit % = \(\frac{\text{Income} - \text{Expenditure}}{\text{Expenditure}} \times 100\).

Let E be the expenditure.

In 2018, the profit percentage for Company Y was 40%.

40 = \(\frac{600 - E}{E} \times 100\)

0.40 = \(\frac{600}{E} - 1\)

1.40 = \(\frac{600}{E}\)

E = \(\frac{600}{1.4} = \frac{6000}{14} \approx 428.57\) crores.
