Question

29) What is 50% of a number whose 200% is 20?​

Answer 1

Let the number be x.

ATQ, 200% of x = 20

$= \frac{200}{100} \times x = 20$

$= x = 10$

Now, 50% of 10 =

$\frac{50}{100} \times x$

$= \frac{1}{2} \times 10$

$= 5$

Therefore, the answer is 5.

Answer 2

20/200=1/10

=1/10×50=5
