Question

One third of a number increased by 2 is equal to 8. The number is a. 12 b. 16 c. 18 d. 2

Answer 1

c

Explanation:

let the number be n then one third of the number is
`(1)/(3)` n snd increased by 2 is
`(1)/(3)` n + 2 , and equating to 8 gives the equation

`(1)/(3)` n + 2 = 8 ( subtract 2 from both sides )

`(1)/(3)` n = 6 ( multiply both sides by 3 to clear the fraction )

3 ×
`(1)/(3)` n = 3 × 6 , that is

n = 18
