• A. 17 : 11
• B. 19 : 11
• C. 11 : 17
• D. 19 : 13
• E. None of these

Answer 1

The correct option is B 19 : 11

Number of mobile phones $=\frac{1650\times 24}{100}=396$
Number of pen drives $=1650\times \frac{1}{6}=275$
Number of calculators $=1650\times \frac{14}{100}=231$
Number of televisions and washing machines $=748$
Number of washing machines $=T+50$
$T+W=748T+T+50=7482T=748-50=698\therefore T=\frac{698}{2}=349$
Washing machines $=349+50=399$
Required ratio $=\frac{399}{231}=\frac{133}{77}=\frac{19}{11}=19:11$
