Question

A number is multiplied by 4. The result obtained is divided by 2 and the final answer is 50. Find the number.

• A. 25
• B. 50
• C. 100
• D. 12.5

Answer 1

The correct option is A

25

Let the number be x

The number is multiplied by 4 = 4x

New number 4x is divided by $2=\frac{4x}{2}$

Forming the equation:

$\frac{4x}{2}=50$

[multiplying each term by 2]

= 4x = 50 x 2

= 4x = 100

[dividing each term by 4]

$=\frac{4x}{4}=x=\frac{100}{4}=25$
