a number consist of 2 digits the digit in tens place is twice unit place the no. formed by reversing the digit is 27 less than original no. find the original

63

Step-by-step explanation:

If x units, then 2x tens

Number is: 2x (10) + x = 21x

Reversing digits:

2x units and x tens,

Number is: x (10) + 2x = 12x

21x - 12x = 27

9x = 27

x = 27/9 = 3

Original number: 21x = 21 (3) = 63
