Question

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

Answer 1

Answer:

25%

Step-by-step 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

$2m=2\times 100=200cm$

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

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

Percentage increase=$\frac{Increase\;value}{Initial\;value}\times 100$

Using the formula

Percentage increase in height=$\frac{40}{160}\times 100$

Percentage increase in height=25%
