Answer is 42

Explaination


Consider the given problem :

Let the number be x,

This can be expressed mathematically as ,
One-third of a number written as 1/3 x

One-third of a number, decreased by six expressed as 1/3x -6

then whole expression become,

1/3x -6 = 8

Now, solving for the above expression

Adding 6 both sides, we have,

(1/3)x - 6 = 8
           +6   +6

It becomes 1/3x+6-6=8 +6
1/3x = 14

Multiply both side by 3 , we get,

3* 1/3x = 14*3

x= 42

Thus, the number is 42.
