The average of five consecutive odd numbers is 95. What is the fourth number in the descending order?
A. 91 B. 95 C. 97 D. None of these Answer: Option DShow Answer
Solution(By Apex Team)
Let the numbers be x, x + 2, x + 4, x + 6 and x + 8
Then,
$\begin{aligned}&\Rightarrow\frac{x+(x+2)+(x+4)+(x+6)+(x+8)}{5}=95\\
&\Rightarrow5x+20=475\\
&\Rightarrow5x=455\\
&\Rightarrow x=91\end{aligned}$
So, the numbers are 91, 93, 95, 97 and 99
Clearly, the fourth number in the descending order is 93
