Question

What is 50℅ of a number whose 200℅ is 20?

Answer 1

Let the number be x.

Given that the 200% of x = 20.

200/100 * x = 20

2 * x = 20

x = 20/2

x = 10.


Then 50% of a number = 50% of 10

                                       = 50/100 * 10

                                       = 5.


Therefore the required number be 5.


Hope this helps!

Answer 2

Let the number be x.


 200% × x = 20.


200/100 × x = 20


2x = 20


x = 20÷2


x = 10.


50% of a number = 50% × 10 = 50÷100×10 = 0.5 × 10 = 5.


The required number be 5.
