The marks obtained by B in P are: 49% * 70 = 34.3 The marks obtained by B in Q are: 79% * 80 = 63.2 The marks obtained by B in R are: 62% * 120 = 74.4 The marks obtained by B in S are: 85% * 125 = 106.25 The marks obtained by B in T are: 56% * 75 = 42 The marks obtained by B in U are: 76% * 150 = 114 Total marks obtained = 34.3 + 63.2 + 74.4 + 106.25 + 42 + 114 = 434.15 Total marks possible = 70 + 80 + 120 + 125 + 75 + 150 = 620
Overall percentage = $$ frac{Total.marks.obtained}{Total.marks.possible}*100$$ = $$ frac{434.15}{620}*100$$ = 70.02%
