The total population (males and females) of city R watching mentalist is what per cent more than the total population (males and females) of city T watching the same TV series?

A) \[8\frac{3}{7}\]

B) \[8\frac{5}{7}\]

C) \[8\frac{4}{7}\]

D) \[7\frac{3}{7}\]

E) \[7\frac{4}{7}\]

Correct Answer: C

Solution :

\[=\frac{50000\times 16}{100}+\frac{50000\times 22}{100}\]\[=8000+11000=19000\]

Total number of people in city T watching mentalist

\[=\frac{5000\times 15}{100}+\frac{50000\times 20}{100}\]\[=7500+10000=17500\]

\[\therefore \]Required percentage \[=\frac{19000-17500}{17500}\times 100\]\[=\frac{1500\times 100}{17500}=\frac{60}{7}=8\frac{4}{7}\]% more
