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

A. What information is compared in the above given double bar graph?

B. Calculate the ratio of minimum temperatures in the year 2008 to the year 2009 for the month of November.

C. For how many months was the minimum temperature In the year 2008 greater than that of year 2009? Name those months.

D. Find the average minimum temperature for the year 2008 for the four months.

E. In which month is the variation in the two temperatures maximum?

Answer :

(A) This graph depicts the minimum temperature in different months of 2 years 2008 and 2009

(B) In month of November

Minimum temperature in 2008 = 18°C

Minimum temperature in 2009 = 15°C

Ratio = 18:15

= 6:5

(C) In 2 months the minimum temperature in year 2008 greater than that of year 2009

Those months are February and November

∵ Bar of 2008 is greater than bar of 2009 in both months

(D) Average minimum temperature of 2008 is

Sum of min temp of 2008 = 12 + 4 + 11 + 18

= 45

Average =

= 11.25°C

(E) In February the variation of temperature is maximum

As

Temp in 2008 = 12

Temp in 2009 = 8

Variation = 12-8

= 4°C
