Question

The average of 5 consecutive even number A, B, C, D and E is 34. What is the product of B and D?

(a) 1088 (b) 1224 (c) 1368 (d) 1152 (e) None of these

Answer 1

(d) Let A = x,
According to the question,
 A + B + C + D + E
= x + (x + 2) + (x + 4) + (x + 6) + (x 8)
⇒5x + 20 = 34 × 5 = 170
⇒B × D = 32 × 36 = 1152
