Q)

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.
