Answer 1

Answer:

b) 5

Step-by-step explanation:

Let the required number = x

now, 200 % of x = 20

⇒ (200/100) × x = 20

⇒ 2x = 20

⇒ x = 10

now, 50% of 10 = (50/100) × 10

=> 5 ans.

Answer 2

${\red{\underline{\underline{\orange{\textsf{\textbf{Question : }}}}}}}$

➡ What is 50% of a number whose 200% is 20.

${\pink{\underline{\underline{\purple{\textsf{\textbf{Answer : }}}}}}}$

◩ The number is 10.

◩ 50% of it is 5

${\pink{\underline{\underline{\purple{\textsf{\textbf{Explanation : }}}}}}}$

Let's assume that, The number is x

• Here, it is told that 200% of x is 20

Therefore,

$\sf \longrightarrow \: 200\% \: of \: x = 20$

$\sf \longrightarrow \: \frac{200x}{100} = 20$

$\sf \longrightarrow \: 2x = 20$

$\sf \longrightarrow \: x = \frac{20}{2}$

$\sf \longrightarrow \: x = 10 \: ans.$

${\pink{\underline{\underline{\purple{\textsf{\textbf{Hence, The number is 10 }}}}}}}$

As we need to find the 50% of it

So,

➪ 50% of x

➪ ½ of 10

➪ 5 ans.
