x + 20 x = 21 x

60 < 21 x <70

try x = 3

63

Alternatively

"If I am less than 70 greater than 60? "

then the possibles are 61, 61 ....69

so the tens is always 6

then if
"My tens digit is double my ones digit."

then the ones digit is 6/2=3

thus the answer is 63.

If the number is less than 70 and greater than 60, the tens digit has to be 6. Now, if the ones digit is half the tens digit, divide 6 in half. The answer is 63.
