The table shows the number of cars sold by dealers P, Q, R, S and T during the first six months of 2022.
What is the percentage increase in the sales of dealer T in February 2022 over January 2022 (approximately)?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 16.42%
Percentage increase \(\displaystyle =\frac{\text{increase}}{\text{earlier value}}\times100\); the January figure is the base.
Dealer T: January 548, February 638
Increase \(=638-548=90\)
Percentage increase \(\displaystyle =\frac{90}{548}\times100=16.42\%\) (approximately)
