• B. 917
• C. 925
• D. 905
• E. None of these

Answer 1

The correct option is D 905

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 $=349+50=399$
Total number of pen drives, calculators and washing machines $=275+231+399=905$
