Answer 2

Let the digit at the unit's place be x.

Digit at tens place = 2x

Original number = (2x)×10 + x = 21x

Number obtained by interchanging the digits = (x)x10 + 2x = 12x From the given information,

12x + 21x = 66

33x = 66

X = 2

:. The unit's digit = 2. Tens Digit = 2 × 2 = 4. Hence, the number is 42.
