The sum of the digits of a two digit number is 14. The difference between the tens digit and the units digit is 2. Find the number
Let the tens and units digits be T and U, respectively
Then: T + U = 14 ------ eq (i)
Also, T - U = 2 ----- eq (ii)
2T = 16 ----- Adding eqs (i) & (ii)
T, or tens digit = , or
8 + U = 14 ----- Substituting 8 for T in eq (i)
U = 14 - 8, or
The number is therefore, .
However, since no clue was given regarding the size of the tens compared to the units digit, the number can also be:
