Question

what is 50% of a no. whose 200% is 20

Answer 1

Let the required no. be x. Then

200% of x = 20
(200/100) *x= 20
2*x = 20
x = 20/2
x = 10

Hence, the number is 10

Now 50%of 10 =(50/100)*10
=>(1/2) *10
=->5 Ans.

Answer 2

Hey Friend...
Here is your answer....

Let the number be x. So,

200% of x = 20
( 200/100 ) * x = 20
2x = 20
x = ( 20/2 )
x = 10

Therefore, the number required is 10.
Now,
50% of the number = ( 50/100 ) * 10
= ( 1/2 ) * 10
= 5

Therefore, the answer is 5.
Hope it helps.
