Yesterday, Integrated Learning posted a 700 level GMAT question on our blog. Today, they have followed up with the answer:
The sum of three integers is even – they can’t all be odd so the product will be even and B and D are eliminated.
To go further we must actually work.
Let’s make the mode be x. If it is a mode and there are three integers it must appear twice. Hence our three numbers are x-13 (the smallest), x and x.
x + x + (x – 13) = 50
3x – 13 = 50
x = 21
8*441 = 3,528
