Correct Answer - Option 3 : 2016 and 2018
Calculation:
Sale in 2015 = 1000
Sale in 2016 = 1290
Sale increase = [(1290 – 1000)/1000 × 100]
⇒ (290/1000 × 100)
⇒ 29000/1000
⇒ 29%
Sale in 2017 = 1100
Sale in 2018 = 1450
Sale increase by more than 25% of the previous year = [(1450 – 1100)/1100 × 100]
⇒ (350/1100 × 100)
⇒ 35000/1100
⇒ 31.81%
∴ The sale increases by more than 25% of the previous year is 2016 and 2018
