Which of the following multipliers will cause a number to increase by 29.7%?
Solution
✅ Correct Option: 4
Increasing a number by $29.7\%$ means the new value is $100\%+29.7\%=129.7\%$ of the old value. As a multiplier that is $\dfrac{129.7}{100}=1.297$ Quick check: $100\times1.297=129.7$, which is exactly $29.7$ more than 100.
