The sum of 5 consecutive even numbers A , B, C, D and E is 130. What is the product of A and E?
Explanation
Let the five consecutive number be A=x, B=x+2, C=x+4, D=x+6 and E=x+8
According to the question
⇒ x+(x+2)+(x+4)+(x+6)+(x+8)=130
⇒ 5x+20=130
⇒ 5x=110
⇒ x=22
∴ A=22
E=x+2= 22+8=30
∴ The product of A and E is A×E=22×30=660.
Hence, Option C is correct.
