40% of the total expenditure of company B from 2015 to 2019 is what percent less than 65% of the total income of company A from 2015 to 2018? (correct to one decimal place)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 15.6%.
Total expenditure of company B from 2015 to 2019 (in crores) = 120 + 125 + 140 + 275 + 300 = 960
40% of the total expenditure of company B from 2015 to 2019 (in crores) = 0.4 × 960 = 384
Total income of company A from 2015 to 2018 = 110 + 150 + 200 + 240 = 700
65% total income of company A from 2015 to 2018 = 0.65 × 700 = 455
Difference = 455 - 384 = 71
Difference percentage = (71/455) × 100 = 15.6% (approx)
