    What are the average marks obtained by all students together in Physics?

    A) 123\[\frac{1}{3}\]

    B) (b) 117\[\frac{1}{2}\]

    C) 123\[\frac{1}{2}\]

    D) 117\[\frac{1}{3}\]

    Correct Answer: B

    Solution :

    Average percentage in Physics = \[\frac{82\text{ }+84+90+64+70+80}{6}\]= \[\frac{470}{6}\] \[\therefore \]Required average marks =\[\frac{476}{6}\]% of 150 = \[\frac{476}{6}\times 150\]= \[\frac{470}{4}\]= \[117\frac{1}{2}\] Calculations (146 - 150) : Population of village U = 60000 \[\therefore \] Population of city Y= \[\frac{60000\times 100}{75}\] = 80000 Population of village P = \[\frac{80000}{2}\] = 40000 Population of village Q = \[\frac{48\times 80000}{100}\] = 38400 Population of village R = \[\frac{3}{5}\times 8000\] = 48000 Population of village S = \[\frac{60\times 48000}{100}\] = 28800 Population of village T = \[\frac{80\times 38400}{100}\] = 30720
