Thrice of a number is 24 more than one-third of it. The number is:

Solution

Let's assume the number is 'y'.

Thrice of a number is 24 more than one-third of it.

$$3y=\frac{y}{3}+24$$

$$3y-\frac{y}{3}=24$$

$$\frac{9y}{3}-\frac{y}{3}=24$$

$$\frac{8y}{3}=24$$

$$\frac{y}{3}=3$$

the number = y = 9
