Question

a number is 3 times the sum of its digits . find the number​

Answer 1

Answer: 27

Step-by-step explanation:

Let the digit at tens be t and the digit at units be y

10 t + y = 3 ( t + y )

10 t + y = 3 t + 3 y

10 t - 3 t + y = 3 y

7 t + y = 3 y

7 t = 3 y - y

7 t = 2 y

t / y = 2 / 7

digit at tens = 2 = 2 x 10 = 20

digit at units = 7 = 7 x 1 = 7

So, the required answer = 20 + 7 = 27
