• A. 80
• B. 75
• C. 85
• D. 105
• E. 115

Answer 1

The correct option is C

85

Marks obtained by A in :

Subject P $⟶$ 68% of 70 $=\frac{68}{100}\times 70=47.6$

Subject Q $⟶$ $\frac{84}{100}\times 80=67.2$

Subject R $⟶$ $\frac{77}{100}\times 120=92.4$

Total marks of A in P, Q and R = 47.6 + 67.2 + 92.4 = 207.2

Marks obtained by F in :

Subject S $⟶$ $\frac{68\times 125}{100}=85$

Subject T $⟶$ $\frac{68\times 75}{100}=51$

Subject U $⟶$ $\frac{71\times 150}{100}=106.5$

Total marks of F in S, T and U = 85 + 51 + 106.5 = 242.5

$\therefore$Required percentage - $=\frac{207.2}{242.5}\times 100=85.44$
