According to the given information, the three respective categories score as a weighted total is 7.4
wi = weighted factor
xi = ratings
Given weights w1 =0.6 , w2 = 0.1, w3 = 0.3
Ratings x1 = 6 ,x2 = 8, x3 = 10
Total of weights = 0.6+0.1+0.3 = 1
Weighted total = 0.6*6 + 0.1*8 + 0.3*10 = 3.6 + 0.8 + 3 = 7.4
Weighted total = 7.4
