A) 47200
B) 45300
C) 47400
D) 47600
E) 45600
Correct Answer: D
Solution :
(d) The number of people who watch arrow in R, Q are T together |
\[=\left( \frac{50000\times 10}{100}+\frac{50000\times 22}{100}+\frac{20000\times 20}{100}+\frac{20000\times 16}{100}+\frac{50000\times 12}{100}+\frac{50000\times 14}{100} \right)\] |
\[=5000+11000+4000+3200+6000+7000=36200\] |
The number of people who do not watch arrow |
\[=34000+12800+37000\] |
\[=83800\] |
\[\therefore \]Required difference \[=83800-36200=47600\] |
