Answer 2

Answer:

(a) 7565

Step-by-step explanation:

→ Given:-

Sum of 5 consecutive numbers is 435.

→ To Find:-

The product of smallest and biggest number.

→ Solution:-

Let the 1st number be x then the consecutive numbers will be x+1,x+2,x+3,x+4.

According to the question:-

x+x+1+x+2+x+3+x+4=435

5x+10=435

5x=435-10=425

$\implies x = \frac{425}{5}$

$\implies x = 85$

The first number=x=85

The last number=x+4=85+4=89

Now, we have to find the product of smallest and biggest number.

→ First number×Last number

→ 85×89

→ 7565
