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

Let the required number be ‘x’.

According to the question:

⇒ 3x + 5 = 50

Subtracting 5 from both sides, we get

⇒ 3x + 5 – 5 = 50 – 5

⇒ 3x = 45

Dividing both sides by 3, we get

⇒ $\frac{3\mathrm{x}}{3}=\frac{45}{3}$

⇒ x = 15

Therefore, the required number is 15.
