If one-third of a number is 6 more than the number itself, then find the number.

Correct option is B

Given:

One- third of a number is 6 more than the number itself

Solution:

Let the number be x

Then one-third of the number = $$\frac{1}{3} of x = \frac{x}{3}$$​​

​$$\frac{x}{3} = x + 6$$​​

​$$\frac{x}{3} -x = 6$$​​

​$$\frac{x-3x}{3} = 6$$​​

-2x = 18

x= -9
