Marks obtained in subjects B

by P = 150 x 68/100 = 102

by Q = 150 x 72/100 = 108

by R = 150 x 75/100 = 112.5

by S = 150 x 62/100 = 93

by T = 150 x 80/100 = 112.5

by V = 150 x 80/100 = 120

by W = 150 x 68/100 = 102

Average marks in subjects B obtained by all students

= 102 + 108 + 1125 + 93 + 1125 + 120 + 102/7

by Q = 75 x 70/100 = 52.5

by R = 75 x 66/100 = 49.5

by S = 75 x 74/100 = 55.5

by T = 75 x 78/100 = 58.5

by V = 75 x 80/100 = 60

by W = 75 x 72/100 = 54

Total marks = 61.5 + 52.5 + 49.5 + 55.5 + 58.5 + 60 + 54 = 391.5
