The sum of 5 consecutive even numbers A, B, C, D and E is 130. What is the product of A and E ?
-
- 720
- 616
- 660
- 672
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
