A survey was done in a Housing Society where the number of Vehicles were categorized according to their Mileage.

The Graph Given shows the Histogram for the Mileage vs The number of vehicles present.

Which of the Following Frequency distribution table is correct for the Graph?

• A. $\begin{array}{cc}\text{Mileage(km/l)}& \text{No.of vehicles}\\ 0-10& 6\\ 10-20& 9\\ 20-30& 8\\ 30-40& 15\\ 40-50& 11\\ 50-60& 3\\ 60-70& 5\end{array}$
• B. $\begin{array}{cc}\text{Mileage(km/l)}& \text{No.of vehicles}\\ 0-10& 6\\ 10-20& 9\\ 20-30& 8\\ 30-40& 15\\ 40-50& 10\\ 50-60& 3\\ 60-70& 5\end{array}$
• C. $\begin{array}{cc}\text{Mileage(km/l)}& \text{No.of vehicles}\\ 0-10& 6\\ 10-20& 9\\ 20-30& 7\\ 30-40& 15\\ 40-50& 11\\ 50-60& 4\\ 60-70& 5\end{array}$
• D. $\begin{array}{cc}\text{Mileage(km/l)}& \text{No.of vehicles}\\ 0-10& 6\\ 10-20& 9\\ 20-30& 7\\ 30-40& 15\\ 40-50& 11\\ 50-60& 3\\ 60-70& 5\end{array}$

Answer 1

The correct option is D

$\begin{array}{cc}\text{Mileage(km/l)}& \text{No.of vehicles}\\ 0-10& 6\\ 10-20& 9\\ 20-30& 7\\ 30-40& 15\\ 40-50& 11\\ 50-60& 3\\ 60-70& 5\end{array}$

$\begin{array}{cc}\text{Mileage(km/l)}& \text{No.of vehicles}\\ 0-10& 6\\ 10-20& 9\\ 20-30& 7\\ 30-40& 15\\ 40-50& 11\\ 50-60& 3\\ 60-70& 5\end{array}$

This table corresponds correctly to all the values given in the Graph. Rest all tables have non-matching values.
