Question

Study the following table carefully and answer these questions given below (figures in 10,000):
Number of five cars produced and rejected (for defects) by a company over the years
$\begin{array}{ccccccccccc}Car& A& & B& & C& & D& & E& \\ Year& Produced& Rejected& Produced& Rejected& Produced& Rejected& Produced& Rejected& Produced& Rejected\\ 2003& 20& 2& 50& 3& 15& 0.5& 80& 5& 60& 4\\ 2004& 35& 3& 45& 2& 20& 0.55& 75& 4& 58& 4\\ 2005& 15& 0.5& 40& 2.5& 17& 0.7& 58& 2& 62& 3.5\\ 2006& 25& 0.25& 42& 2.3& 25& 1.5& 65& 3& 40& 1.5\\ 2007& 30& 1.5& 48& 2.5& 30& 2.0& 68& 3& 45& 2\\ 2008& 27& 1.5& 41& 2.1& 26& 1.75& 72& 3.5& 50& 2.3\end{array}$

In the year 2004, in case of which cars was the rejection below five percent?

• A. A
• B. B or E
• C. B and E
• D. C and D
• E. None of these

Answer 1

The correct option is E None of these

In the year 2004:
Rejection for Car A = $\frac{3}{35}$ $\times$ 100 = 8.57%
Rejection for Car B = $\frac{2}{45}$ $\times$ 100 = 4.44%
Rejection for Car C = $\frac{0.55}{20}$ $\times$ 100 = 2.75%
Rejection for Car D = $\frac{4}{75}$ $\times$ 100 = 5.33%
Rejection for Car E = $\frac{2}{45}$ $\times$ 100 = 6.89%

Hence, the rejection was below 5% for the cars B & C.
