Study the double bar graph given below and answer the questions that follow:
(a) What information does the above double graph depict?
(b) Name the fruits for which the cost of 1 kg is greater in City I as compared to City II.
(c) What is the difference of rates for apples in both the cities?
(d) Find the ratio of the cost of mangoes per kg in City I to the cost of mangoes per kg in City II.
Solution:
Given, the figure represents a double bar graph.
(a) We have to determine the information depicted by the graph.
The double graph depicts the cost of different fruits per kg in City I and CIty II.
(b) We have to determine the fruits for which the cost of 1 kg is greater in City I as compared to City II.
From the graph,
The cost of 1 kg fruits in City I is greater than City II for Apple, Banana, Mango and Cherry.
(c) We have to find the difference of rates for apples in both the cities.
Cost of 1 kg apple in City I = ₹82
Cost of 1 kg apple in City II = ₹75
Difference of rate = 82 - 75
= ₹7
Therefore, the difference of rates for apples in both the cities is ₹7.
(d) We have to find the ratio of the cost of mangoes per kg in City I to the cost of mangoes per kg in City II.
Cost of mangoes per kg in City I = ₹75
Cost of mangoes per kg in City II = ₹60
Ratio = 75 : 60
= 15 : 12
= 5 : 4
Therefore, the required ratio is 5 : 4
