  1. The sum of 5 consecutive even numbers A, B, C, D and E is 130. What is the product of A and E ?
    1. 720
    2. 616
    3. 660
    4. 672
  1. Correct Option: C

    Let 5 consecutive even number be A = x, B = x+2, C = x+4, D = x + 6 and E = x + 8.

    According to question
    x + x +2 + x + 4 + x + 6 + x + 8 = 130
    ⇒ 5x + 20 = 130
    ⇒ x = 22
    ∴ A = 22, E = 22 + 8 = 30.
    ∴ Multiplication of A and E = 22 x 30
    = 660
