Study the double bar graph given below and answer the questions that follow:

$i.$ What has been compared in the given double bar graph$?$
$ii.$ What is the ratio of minimum temperatures in the year $2015$ to the year $2016$ in the month of November$?$
$iii.$ Name the months in which the minimum temperature in $2015$ was greater than that in $2016?$
$iv.$ Find the average minimum temperature for the year $2016$ for the given four months.
$v.$ In which month is the variation in two temperatures maximum$?$

Answer

$i.$ Minimum temperature for the monts of Nov, Dec, Jan and Feb of $2015$ and $2016$ have been compared.
$ii.$ Ratio of minimum temperature in $2015$ to minimum temperature in $2016$ during the month of Nov. $=\frac{18}{14}=\frac{9}{7}$
$\Rightarrow$ Ratio$=9:7$
$iii.$ In November and February the minimum temperature in $2015$ was greater than that of $2016.$
$iv.$ Average minimum temperature for the year $2016 =\frac{14+13+8+9}{4}=\frac{44}{4}=11^\circ\text{C}$
$v.$ November variation $= 18 - 14 = 4$
December variation $= 13 - 11 = 2$
January variation $= 8 - 5 = 3$
February variation $= 11 - 9 = 2$
During November the variation in two temperatures is maximum.
