Question

If 110% of a number is 528, then the number is:

a) 475.2
b) 52.8
c) 480
d) 580.8
e) 475

Answer 1

c) 480

Explanation:

Any percentage can be converted to a number ratio by dividing by 100%.

E.g. 100%/100% = 1

Following this concept, we can find the equivalent of 110% :

110%/100% = 1.1

Since 528 is 1.1 times the number we are looking for, we just need to divide 528 by 1.1 to find our number. This is because 1.1/1.1 = 1

528/1.1 = 480

Hope this helped!
