Answer 1

Answer:

62

Step-by-step explanation:

Let xy is the number.

Given x=3y and x+y=8.

->3y+y=8=>4y=8

y=2

x=3(2)

x=6

Answer 2

Answer:

Step-by-step explanation:

Let the ten's and one's digit number be x and y respectively,

ATQ,

x=3y

=> x-3y=0             ---(1)

and,

x+y=8

=> 3x+3y=24        ---(2)

Adding (1) and (2), we get,

x+3x-3y+3y=0+24

=> 4x=24

=> x=6

Substituting the value of x in (1), we get,

6-3y=0

=> 3y=6

=> y=2

∴ The 2-digit number is 62.
