According to the numerical puzzler, Digit total means adding up the digits in the number and then seeing if it is less than ten. Eg. 1111 = 1+1+1+1 = 4 and so is less than 10. 76 would be 7+6 = 13 and so would not be less than 10. Hope this helps?

97.97 is less than 100 and more than 89.the tens digit (which is 9) is two more than the ones digit (which is 7)
The ones digit is 5 less than 10 (10-5=5) The tens digit is 2 more than the ones digit (5+2=7) The entire number is less than 200. It could be either "75" or "175", but is probably "175" or they would have said that the entire number was less than 100.
that is 42
