What is the value of \(x\) if the mean of \(8,6,7\), \(5, x\) and 4 is 7 ?
- A 10
- B 12
- C 8
- D 6
Answer & Solution
Correct Answer
(B) 12
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \text {Mean }=7 \\ & \begin{aligned} \frac{8+6+7+5+x+4}{6} & =7 \\ 30+x & =42 \\ x & =12 \end{aligned} \end{aligned}\) Hence, option (b) is correct.
