In a two-digit number, the sum of digits is (11) and the tens digit is (3) more than the units digit. What is the number?

Answer and explanation

Correct answer: (74)

The direct answer is option C, 74. Let the tens digit be x and the units digit be y. The two facts become x+y=11 and x-y=3, because the tens digit is 3 greater. Add the equations: 2x=14, so x=7. Substituting in x+y=11 gives 7+y=11, hence y=4. A two-digit number with tens digit 7 and units digit 4 is 74. Option A, 65, has digit sum 11 but 6 is only 1 greater than 5, not 3. Option B, 83, has sum 11, but 8 is 5 greater than 3. Option C works because 7+4=11 and 7-4=3. Option D, 92, has sum 11, but 9-2=7. Memory cue: for digit questions, write sum and difference equations, then add them to find the tens digit.
