Question

Question 6(i)
Take the data giving the minimum and the maximum temperature of various cities given in the beginning of this Chapter. Plot a double bar graph using the data and answer the following:
Temperature of Cities as on 20.6.2006
$\begin{array}{ccccc}City& Ahmedabad& Amritsar& Bangalore& Chennai\\ Max.& {38}^{\circ }C& {37}^{\circ }C& {28}^{\circ }C& {36}^{\circ }C\\ Min.& {29}^{\circ }C& {26}^{\circ }C& {21}^{\circ }C& {27}^{\circ }C\\ City& Delhi& Jaipur& Jammu& Mumbai\\ Max.& {38}^{\circ }C& {39}^{\circ }C& {41}^{\circ }C& {32}^{\circ }C\\ Min.& {28}^{\circ }C& {29}^{\circ }C& {26}^{\circ }C& {27}^{\circ }C\end{array}$
Which city has the largest difference in the minimum and maximum temperature on the given data?

Answer 1

Data represented by double bar graph is as follows:

Jammu has the largest difference in temperature.
Here,
Maximum temperature= ${41}^{\circ }C$
Minimum temperature = ${26}^{\circ }C$.
$\therefore$ Difference = ${41}^{\circ }C-{26}^{\circ }C={15}^{\circ }C$
