Question

If the sum of three consecutive numbers is 39, find the numbers.

• A. 10,11,12
• B. 12,13,14
• C. 33,34,35
• D. 23,24,25

Answer 1

The correct option is B 12,13,14

Let the smallest number be '$x^{\prime }.$
So, the other two numbers can be written as $x+1$ and $x+2$.
Given, $x+(x+1)+(x+2)=39\Rightarrow 3x+3=39\Rightarrow 3x=39-3=36\Rightarrow x=\frac{36}{3}=12$

$Sincex=12,x+1=13andx+2=14$
Thus, the numbers are 12, 13 and 14.
