Question

Out of six consecutive numbers the sum of first three is $27$. What is the sum of next three?

• A. $30$
• B. $40$
• C. $36$
• D. $45$

Answer 1

Answer: (C)

$36$

Let the first three consecutive numbers be $x,x+1$ and $x+2$.
Then, $x+x+1+x+2=27$
$\Rightarrow 3x=24$

$\Rightarrow x=8$
$\therefore$ The first three numbers are $8,9,10$.
$\Rightarrow$ The next three numbers are $11,12,13$.
Hence, the required sum $=11+12+13=36$.
