Question

if 50%of a number is 20 what is 75% of the number

Answer 1

50/100 of x = 20
x = 20× 100/50
x = 20× 2
x = 40

therefore,
75/100 of 40
= 3/4 × 40
=3 × 10

Answer 2

Given : 50% of a number is 20

To find : 75% of that number.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the 75% of the said number)

Let, the said number = x

50% of the said number :

= x × 50%

= x × (50/100)

= x/2

According to the data mentioned in the question,

x/2 = 20

x = 20 × 2

x = 40

So, the said number = x = 40

Now, 75% of the said number will be :

= 40 × 75%

= 40 × (75/100)

= 30

(This will be considered as the final result.)

Hence, the 75% of the number is 30
