Image
(i) What information does the above double graph depict?
(ii) Name the fruits for which cost of 1 kg is greater in City I as compared to City II.
(iii) What is the difference of rates for apples in both the cities?
(iv) Find the ratio of the cost of mangoes per kg in City! to the cost of mangoes per kg in City II.
✓

Answer

After the study of double bar graph,
Cost of apple in City I = 82
Cost of apple in City II =75
Cost of banana in City I =45
Cost of banana in City II = 32
Cost of mango in City I =75
Cost of mango in City II =60
Cost of watermelon in City I = 20
Cost of watermelon in City II =26
Cost of cherry in City I = 38
Cost of cherry in City II = 30
(i) Clearly, the double bar graph compares the cost of different fruits per kg in city I and II.
(ii) Cost of apple in City $I =82$, where in City II is $=75$ Cost of Banana in City $I =45$, where in City $II =32$ Cost of Mango in City I $=75$, where in City $II =60$ Cost of Cherry in City I $=38$, where in City $II =30$ Hence, apple, banana, mango, and cherry prices/costs in City I are greater than City II.
(iii) Difference of rates for apples in cities I and II $=82-75=$₹ $7$ per kg
(iv) The ratio of the cost of mangoes per kg in City I to the cost of mangoes per kg in City $II =75: 60=5: 4$
