​

Answer 1

Answer:

Now as per the given question one of the two digits of a two digit number is three times the other digit. Now the number that we took was xy and hence 26. So, option (b) is correct. And if we would have taken x = 3y then the answer that we get is 62.

Answer 2

ANSWER = 62 , 26

• let the first number be x

given,

• the second number = 3x

general formula of 2 digit number = 10 x + y

applying here ,

two digit number = 10 (3x) + x

= 30 x + x

= 31x

interchanging , = 10 x + 3x

= 13x

13x + 31 x = 88

44x = 88

x = 88 /44

= 2

numbers = 10x + 3x

= 20 + 6

= 26

other number = 62
