Q)

The sum of the five consecutive numbers is equal to 170. What is the product of largest and the smallest numbers?

    • Explanation

    Let the five consecutive numbers are x,(x+1),(x+2),(x+3),(x+4)

    According to the question

    ⇒ x+(x+1)+(x+2)+(x+3)+(x+4)=170

    ⇒ 5x+10=170

    ⇒ x=32

    ∴The product of largest number is =(x+4)

    = 32+4=36

    ∴ The Required product ⇒ 32×36=1152.

    Hence, Option C is correct.
