Question

the unit digit is three time the tens digit of atwo digit no.when digits are reversed we get 36 more than no. find no.

Answer 1

Tens digit = x
Ones Digit = 3x

Sum without reversing = 10 (x) + 3x = 13x

When reversed

Sum = 10 (3x) + x = 31x

New no - given no = 36

31x - 13x = 36
18x = 36
x = 36/18
x = 2

So tens digit = x = 2
ones digit = 3 (2) = 6

The no is 26
