The table shows the expenditure of a factory on different items in the years 2015 to 2019.
The total expenditure on fuel and transport in the years 2015, 2017 and 2018 is approximately what percent less than the total expenditure on salary in 2016 and 2019?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 50.48%
"What percent less than" compares the difference with the amount after "than", here the salary total.
Fuel and transport (2015, 2017, 2018) \(=96+135+124=355\)
Salary (2016, 2019) \(=328+389=717\)
Difference \(=717-355=362\)
\(\displaystyle\frac{362}{717}\times100\approx50.49\%\); the nearest option is 50.48%
