Question

a number is three times the sum of its digits.Find the number​

Answer 1

Answer - 27

Explanation -

A two digit number may be written as 10(tens digit) + (ones digit). For example, 38 = 10(3) + 8.

Let x = tens digit and y = ones digit

So, 10x+y = 3(x+y)

Therefore, 7x = 2y

The choices for y are 0, 1, 2, ... ,9. Since x must be an integer, the only value of y that works is 7.

So, y = 7 and x = 2. In other words, the number is 27.
