Study the following graph and answer the question:

Line graph of percent profit earned by company ABC: 45 in 2019, 30 in 2020, 40 in 2021 and 55 in 2022

Profit Percent = \(\frac{Income - Expenditure}{Expenditure} \times 100\)
If the income of the company in 2022 was ₹ 620 crores and the expenditure in 2019 was ₹ 300 crores, then the sum of expenditure in 2022 and the income in 2019 (in ₹ crores) is

  • A.780
  • B.810
  • C.825
  • D.835

Answer: D

The sum is 835 crore rupees. The graph gives profit percentages of 45 (2019), 30 (2020), 40 (2021) and 55 (2022). In 2022 the income is 620 with a profit of 55 %, so the expenditure is \[\frac{620}{1.55} = 400\] In 2019 the expenditure is 300 with a profit of 45 %, so the income is \[300 \times 1.45 = 435\] The required sum is 400 + 435 = 835. The option 780 would come from using the wrong year's profit, and 810 and 825 do not follow from these values.
