Question

A number added to itself seven additional times is fourteen more than the number. What is the number?

A.9/14
B.2
C.7
D.–2

Answer 1

Correct option is:

B. 2

Explanation:

Let x is the number.

A number added to itself seven additional times ( x+(x+x+x+x+x+x+x)=8x)

is fourteen more than the number.

⇒ 8x=x+14

⇒ 7x=14

dividing by 7 on both sides

⇒ x=2

Hence, Correct option is:

B. 2

Answer 2

We represent the unknown number by x. If the number is added to itself seven times, the number would be 8x. The equation we can derived from the condition is,
8x = x + 14
The value of x is 2. Therefore, the answer is letter B. 2.
