a number that is 20% greater than b

Answer 1

Answer:

A number that is 20% greater than b

Let us consider ‘a’ is 20% grater than b

Then b is the base. Let value of b = 100

So, the value of a = 120

Answer 2

Given:

A number that is 20% greater than another number

To Find:

The number

Solution:

Let the number be b and the other number which is 20% greater than b be a.

If b = 100

Then,

a is 20% greater

= 20/100

= 1/5

a =  ((b+1/5b)/b)100

a = (6/5)×100

a = 120%

Hence, a number that is 20% greater than b is 120%
