Total marks obtained by Amit, Abhi and Anuj in subject E = (80 + 74 + 84) ×150100\times\dfrac{150}{100} = 357

Total marks obtained by all the six student in subject B = (85 + 65 + 75 + 55 + 65 + 70) ×80100\times\dfrac{80}{100}= 332

The required percentage = 357−332332×100=7.5\dfrac{357-332}{332}\times100=7.5%
