Solved Questions on Data Handling
Directions(1-2):Carefully observe the bar graph which represents the height of the different trees in feet and answer the following questions.
1. What is the difference in the heights of mango and coconut trees?
a) 1 foot
b) 2 feet
c) 3 feet
d) 4 feet
Answer: a) 1 foot
Explanation: From the graph,
Height of mango tree = 3 feet
Height of coconut tree = 2 feet
The difference in the heights of mango and coconut trees = 3 − 2
= 1 foot
2. The original height of the tree is provided in the bar graph. If the height of the orange tree is increased to 0.25 feet every six months after the given height, what is the height of the orange after 3 years?
a) 2.5 feet
b) 3.5 feet
c) 4.5 feet
d) 5.5 feet
Answer: d) 5.5 feet
Explanation: Height of orange tree = 4 feet
Increased in height of orange tree every six months = 0.25 feet
Increased in height of orange tree every year = 0.25 × 2
= 0.5 feet
Increased in height of orange tree every 3 years = 0.5 × 3
= 1.5 feet
Height of orange tree after 3 years = 4 + 1.5
= 5.5 feet
3. The below pictograph shows the information regarding the names of people who purchased apples. Answer the following questions based on this pictograph.
What is the quantity of apples purchased by Kelly?
a) 1 kg 500 g

= 2000 g + 500 g
= 2 kg 500 g
