Question

It takes 3 liters of paint to cover an area of 24 square meters
What percentage increase in the quantity of paint would be
required to cover an area of 50.4 square meters?​

Answer 1

Answer:

3 liter : x liter :: 24 m2 : 50.4 m2

3 / x = 24 m2 / 50.4 m2

3 * 50.4 m2 = x * 24 m2

151.2 / 24 = x

6.3 = x

Hence, 6.3 liters of paint are required. Now, we need to find what percentage increase in 3 is 6.3?

X % * 3 = 6.3 - 3

X / 100 * 3 = 3.3

3x = 330

X = 330 / 3

X = 110

So, the percentage increase is 110 %

What percentage of 25 is 35?

Solution:

X % * 25 = 35

X / 100 * 25 = 35

25x = 3500

X = 3500 / 25

X = 140
