Question

The height of a sunflower increases from 160cm to 2 metres in a week. Find the percentage increase in height

Answer 1

25%

Explanation:

We are given that

Initial height of sunflower=160 cm

After increasing

Final height of sunflower=2m

We have to find the percentage increase in height.

1 m=100 cm

`2m=2* 100=200cm`

Increase in height of sunflower=Final height of sunflower-initial height of sunflower

Increase in height of sunflower=200-160=40cm

Percentage increase=
`(Increase\;value)/(Initial\;value)* 100`

Using the formula

Percentage increase in height=
`(40)/(160)* 100`

Percentage increase in height=25%
