Question

10% of 25% of a number is 20.What is the number?

Answer 1

Let the number be "x"

25% of x = 25*x/100 = x/4

10% of x/4 = 10*x/(4*100) = x/40

But its given as 20

x/40 = 20

x = 800

Therefore the number is 800!

Answer 2

.

Let the required number be "x"

10% of 25% of the number is 20

This can be translated mathematically as,
10% [ 25% (x) ] = 20

(10/100) * (25/100) * x = 20

This gives,
10 * 25 * x = 20 * 100 * 100

x = 20 * 4 * 10

x = 800

Hence, the required number is 800.

Answer 3

Let the number be "x"

25% of x = 25*x/100 = x/4

10% of x/4 = 10*x/(4*100) = x/40(coz its saying 2)

But its given as 20

x/40 = 20

x = 800

Answer 4

let the number be 'x'
25%of x=25/100*x=x/4
10% of 25% of x=10/100*x/4=x/40
given x/40=20 x=20*40=800
therefore x=800

Answer 5

Let x is the desired number
So, x*25/100*10/100=20
x=20*100*100/250
=800

Answer 6

Here is a easy step-to-step guide:

1) The parenthesis is where you multiply the numbers. The "x" in that equation is "the number", but it doesn't really matter what "variable" you use. (10%)(25%)(x) = 20

2) You must now change 10% and 25%, into a decimal. To do so, move the decimal place two times to the left. (When your trying to convert a decimal to a percent, then you do the opposite, which is two times to the right.) So that'll end you up with the following: (.10)(.25)(x) = 20

3) Now simply multiply and your total is: .0250x = 20

4) Then you divide .0250, to 20. The .0250 obviously gets canceled out and your final answer is... x = 800

5) Your total is " x = 800 "

Answer 7

hi
10/100(25/100(x))=20
25/100(x)=20*(100/10)
=200
x=200*(100/25)
x= 800
the number is 800

Answer 8

10%(25% x 80 = 20) = 2, because 10% 0f 20 is 2

Answer 9

(10/100) * (25/100) * number = 20
Therefore, number = 20 * 100 * 100 / (10 * 25) = 800

Answer 10

800
