Question

Marvin was 1.55m tall a year ago. now,he is 1.62m tall. find the percentage increase in Marvin's height correct to 2 decimal places​

Answer 1

4.52 %

Explanation:

the percentage increase in height is calculated as

`(increase)/(original)` × 100%

increase in height = 1.62 - 1.55 = 0.07 ,

then

% increase =
`(0.07)/(1.55)` × 100% = 0.045.. × 100% ≈ 4.52% ( to 2 decimal places )
