By which of the following numbers should a number be multiplied so that it increases by 29.7%?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 1.297
Increasing a number by 29.7% means keeping the whole number (100%) and adding 29.7% of it.
New value \(=100\%+29.7\%=129.7\%\) of the number
\(\displaystyle 129.7\%=\frac{129.7}{100}=1.297\)
The multiplier is 1.297.
