• D. 47600
• E. 45600

Answer 1

The correct option is D 47600

The number of people who watch Arrow in R, Q and T together
$=(\frac{50000\times 10}{100}+\frac{50000\times 22}{100}+\frac{20000\times 20}{100}+\frac{20000\times 16}{100}+\frac{50000\times 12}{100}+\frac{50000\times 14}{100})$
$=5000+11000+4000+3200+6000+7000=36200$
The number of people who do not watch Arrow
$=34000+12800+37000=83800$
$\therefore$Required difference$=83800-36200=47600$
