What is the ratio between total marks obtained by D in Maths, Science and English together and the total marks obtained by F in these subjects together respectively ?

• A. 209 : 215
• B. 215 : 209
• C. 206 : 223
• D. 223 : 206
• E. None of these

Answer 1

The correct option is A 209 : 215

Total marks obtained by D in Maths, Science and English together $=68+\frac{72\times 150}{100}+\frac{66\times 50}{100}$
=68 + 108 + 33 = 209
Total marks obtained by F in Maths, Science and English together $=68+\frac{64\times 150}{100}+\frac{80\times 50}{100}$
=79 + 96 + 40 = 215
$\therefore$ Required ratio = 209: 215
