The table gives the percentage profit earned by two companies A and B during 2013 to 2018. Profit percentage is measured on expenditure, so income = expenditure plus profit.
| Year | A profit | B profit |
|---|---|---|
| 2013 | 20% | 35% |
| 2014 | 32% | 30% |
| 2015 | 40% | 50% |
| 2016 | 25% | 40% |
| 2017 | 30% | 30% |
| 2018 | 15% | 40% |
If the expenditure of company A in 2013 and company B in 2018 are the same, and the income of company B in 2018 is Rs 77 lakh, then what is the income of company A in 2013?
ARs 55 lakh
BRs 66 lakh ✓ Correct
CRs 56 lakh
DRs 64 lakh
Correct answer: (B) Rs 66 lakh
Explanation
B's 2018 profit is 40%, so 1.4 times the expenditure equals 77, giving expenditure 55 lakh; A's 2013 profit is 20%, so A's income is 55 times 1.2 = 66 lakh. Hence option B.
