P, Q, R, S, T and U are six consecutive odd numbers and their average is 52. What is the product of P and U ?

2212
2154
2349
2679

Correct Answer: 2679

Explanation:

Let x, x+2, x+4, x+6, x+8 and x+10 are six consecutive odd numbers.

Given that their average is 52

Then, x + x+2 + x+4 + x+6 + x+8 + x+10 = 52×6

6x + 30 = 312

x = 47

So Product = 47 × 57 = 2679
