Question

Find 60% of a number if 15% of the number is 400.
​

Answer 1

Step-by-step explanation:

Here the question is that if 15% of a number has a value of 60 then what is that number that is we have to find 100%

Let the number be x

If 15 ———> 60

Then

100———> x

=> 15/100=60/x

=> x=400

A very easy way to find percentages is suppose if we take a number eg 50 and want 10% decrease one decimal i.e 5.0 and for 1% we should decrease 2 decimals i.e 0.5 and so on.If we if need to find 12% we can do it by just adding 10% and 2% i.e

12%=10%+2%=(5.0+2 (0.5))=6

In this way we find percentage of many number easily

Answer 2

Answer:

Let the number be "x"

Therefore, according to the question

15% of x = 400

i. e. 15/100 X x = 400

x = 400 X 100 / 15

Therefore, "x" = 40000 / 15

Hence, 60% of x is

=60/100 X x

=6/10 X 40000/15

=1600

Therefore, 60% of a number is 1600
