The sum of two numbers is (29) and their difference is (7). What is the larger number?

Answer and explanation

Correct answer: (18)

The direct answer is option C: 18. Let the larger number be x and the smaller number be y. Their sum gives x+y=29. Their difference gives x-y=7. Add the equations: 2x=36, so x=18. Then y=29-18=11, and 18-11=7, confirming the interpretation. Option C is correct because 18 is the larger number and the pair has sum 29 and difference 7. Option A, 15, would pair with 14 to make sum 29, but the difference is only 1. Option B, 16, would pair with 13, giving difference 3. Option D, 20, would pair with 9, giving sum 29 but difference 11. The formula shortcut is useful: larger number = (sum+difference)/2 = (29+7)/2 = 18. Memory cue: add sum and difference to get twice the larger number.
