Question

If the sum of three consecutive integers is $63$. Find the smallest number.

• A. $11$
• B. $15$
• C. $23$
• D. $20$

Answer 1

The correct option is D $20$

Let the smallest integer be $x$.

The three consecutive numbers $=x,x+1,x+2$

Given, $x+x+1+x+2=63$

$3x+3=63$

$3x=60$

$\therefore x=20$
