Question

What is the difference between the number of AC's of Quality A and Quality B?

• A. 25
• B. 50
• C. 35
• D. 40
• E. None of these

Answer 1

The correct option is A 25

Total $=500units$
$\begin{array}{cc}QualityA& QualityB\\ Fans=500\times \frac{1}{5}\times \frac{65}{100}=65& Fans=500\times \frac{1}{5}\times \frac{35}{100}=35\\ ACs=500\times \frac{15}{100}\times \frac{2}{3}=50& ACs=500\times \frac{15}{100}\times \frac{1}{3}=25\\ Refrigerators=500\times \frac{1}{4}-40=85& Refrigerators=40\\ Ovens=200-20=180& Ovens=200\times \frac{10}{100}=20\end{array}$
Total Ovens $=500–(65+35+50+25+85+40)=200$
Required difference $=50-25=25$
