• C. 59 : 42
• D. 55 : 43
• E. 59 : 45

Answer 1

The correct option is B 55 : 48

Total number of females who watch breaking bad in city Q and S together
$=\frac{20000\times 10}{100}+\frac{30000\times 30}{100}$
$=2000+9000=11000$
Total number of females who watch mentalist in city Q and S together
$=\frac{20000\times 30}{100}+\frac{30000\times 12}{100}$
$=6000+3600$
$=9600$
$\therefore$ Required ratio = $11000:9600=110:96=55:48$
