• A. $123\frac{1}{3}$
  
• B. $117\frac{1}{2}$
  
• C. $123\frac{1}{2}$
  
• D. $117\frac{1}{3}$
• E. None of these

Answer 1

The correct option is B $117\frac{1}{2}$


Average percentage in Physics:-
$=\frac{82+84+90+64+70+80}{6}=\frac{470}{6}$
$\therefore$ required average marks
$=\frac{470}{6}\%of150=\frac{470}{6}\times 150=\frac{470}{4}=117\frac{1}{2}$
