Answer:
Weighted total will be 7.
So option (c) will be the correct answer
Explanation:
We have given factor of weight [tex]w_1=0.6kg[/tex], [tex]w_2=0.1kg[/tex] and [tex]w_3=0.3kg[/tex]
Rating in three respective category [tex]x_1=6[/tex] , [tex]x_2=8[/tex] and [tex]x_3=10[/tex]
Total weight is given by [tex]x=\frac{\sum w_ix_i}{\sum w_1}[/tex]
So [tex]x=\frac{\sum w_ix_i}{\sum w_1}=\frac{6\times 0.6+8\times 0.1+10\times 0.3}{0.6+0.1+0.3}=7.4[/tex]
So weighted total will be 7.4
So option (c) is the correct option
