Explained:
Look at the question:
My tens digit is double my ones digit.
I am less than 70 and greater than 60.
what number am I?
So
10’s digit is double my 1’s digit.
10's digit can only be in the range of 60 and 70, [61-69]
So
The 10's digit has to be 6
Read again, my 10's digit is double my 1's digit.
So if my 10's digit is 6 what number doubles into 6?
3 doubled =6
or 6 halved =3
Answer 63
Take the same question again and replace the 70 and 60 with 20 and 30 and see what answer you come up with.
Will be 21.
