The number of apples in the 12 bag is 96
Solution:
Given that, there are 12 bags of apples on a market stall.
The mean number of apples in each bag is 8.
We have to calculate the number of apples in the 12 bag.
The mean of "n" observations is given as:
[tex]\text { mean of n observations }=\frac{\text { sum of observations }}{\mathrm{n}}[/tex]
[tex]\text { Here, in our problem, mean }=\frac{\text {total number of apples}}{12}[/tex]
[tex]\begin{array}{l}{\rightarrow 8=\frac{\text { total number of apples }}{12}} \\\\ {\rightarrow \text { total number of apples }=8 \times 12=96}\end{array}[/tex]
Hence, there are 96 apples in 12 bags.
Assuming the mean number of apples in each bag is 8. The number of apples in the 12 bag is 9 apples.
First step
Total number of apples=12×8
Total number of apples=96
Second step
Number of apples in the 12 bag=96-(6+4×7+8×2+9×3+10)
Number of apples in the 12 bag=96-87
Number of apples in the 12 bag=9 apples
Inconclusion the number of apples in the 12 bag is 9 apples.
