The bar graph shows the number of members of a club from 2019 to 2023.
By what percentage did the number of members increase from 2019 to 2023?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 75%
Percentage increase \(\displaystyle =\frac{\text{increase}}{\text{earlier value}}\times100\); the 2019 figure is the base.
2019: 120 members; 2023: 210 members
Increase \(=210-120=90\)
Percentage increase \(\displaystyle =\frac{90}{120}\times100=75\%\)
Membership rose by 75% from 2019 to 2023.
