Answer 1

Answer:

B is the correct answer.

let the sum be x

then 40% of x= 120

40/100×x=120

x= 120×100/40

x= 300

Answer 2

Answer:

The required number is $300$.

∴ Option (B) is correct.

Step-by-step explanation:

Given : $40$% of a sum = $120$

To find : The number=?

Solution :

• It is given that $40$% of a sum = $120$
• We have to find that number.
• Let, $x$ be the number.
• According to given condition, the required equation becomes,

     $40$% of $x$ = $120$

      ∴ $\frac{40}{100} *x=120$

           ∴ $\frac{40x}{100} =120$

• Transpose $100$ to other side, we get

           ∴ $40x=120*100$

           ∴ $40x=12000$

• Transpose $40$ to other side, we get

              ∴ $x=\frac{12000}{40}$

              ∴ $x=300$

• ∴ The required number is $300$.

• ∴ Option (B) is correct.
