Question

Find a two digit number which is 3 times the sum of its digit

Answer 1

Answer:

two digit number = 10x + y

=> 3(x+y) = 10x+y

=> 3x + 3y = 10 x + y

=> 7x = 2y

=> x/ y = 2/7

=> x = 2 and y= 7

=> two digit number = 27

Answer 2

hey mate here is your answer:

let the digit be 10x+y,

According to question:

$10x + y = 3(x + y)$

$= > 10x + y = 3x + 3y$

$= > 7x = 2y$

$\frac{x}{y} = \frac{2}{7}$
