Question

The average of 5 consecutive odd numbers A, B, C, D and E is 55. What is the product of B and D?

• A. 2915
• B. 3127
• C. 3021
• D. 2703
• E. None of these

Answer 1

The correct option is C

3021

From the question, x + x + 2 + x + 4 + x + 6 + x + 8 = 5 $\times$ 55

Or 5x + 20 = 275

Or 5x = 275 - 20

Or x = $\frac{255}{5}$ = 51

$\therefore$ A = 51; B = 53; C = 55; D = 57 and E = 59

From the question B $\times$ D = 53 $\times$ 57 = 3021
