Answer 2

27 is a number which is very peculiar.

• we need to assume the number in very basic way.

Units> Tens> Hundred.

• It is said Sum of two digit of number that means, it is a 2 digit number confirmed.

Let those 2 digit take x,y

It is written as

$10X + Y$ ( Y is units place and for tens place X is multiplied with 10)

• So According to the given condition,The number is three times the sum of its digits

$3(X+Y)= 10X+Y$

$3X+3Y=10X+Y$

take x values all in right side and y values all in left side,

$3Y-Y=10X-3X$

subtraction the x values and y values

$7X= 2Y$

So   $X=2, Y=7$

Number (xy) is $27$
