Answer 2

If a number is tripled and the result is increased by 5, we get 50.

To find,

The number.

Solution,

Let us assume that $a$ be the unknown number.

As it is given that, If a number is tripled and the result is increased by 5, we get 50. Therefore,

$\begin{array}{l}\Rightarrow a(3) + 5 = 50 \\ \Rightarrow 3a + 5 = 50 \\ \Rightarrow 3a = 50 - 5 \\ \Rightarrow 3a = 45 \\ \Rightarrow a = \frac{45}{3} \\ \Rightarrow a = 15\end{array}$

Hence, the unknown number is 15.
