For an experiment in Botany, two different plants, plant A and plant B were grown under similar laboratory conditions. Their heights were measured at the end of each week for 3 weeks. The results are shown by the following graph.
- How high was Plant A after (i) 2 weeks (ii) 3 weeks?
- How high was Plant B after (i) 2 weeks (ii) 3 weeks?
- How much did Plant A grow during the 3rd week?
- How much did Plant B grow from the end of the 2nd week to the end of the 3rd week?
- During which week did Plant A grow most?
- During which week did Plant B grow least?
- Were the two plants of the same height during any week shown here? Specify.

उत्तर
- After 2 weeks, the height of plant A was 7 cm.
- After 3 weeks, the height of plant A was 9 cm.
- After 2 weeks, the height of plant B was 7 cm.
- After 3 weeks, the height of plant B was 10 cm.
-
- Growth of plant A during 3rd week = 9 cm − 7 cm = 2 cm
- Growth of plant B from the end of the 2nd week to the end of the 3rd week
- = 10 cm − 7 cm = 3 cm
- Growth of plant A during 1st week = 2 cm − 0 cm = 2 cm.
- Growth of plant A during 2nd week = 7 cm − 2 cm = 5 cm.
- Growth of plant A during 3rd week = 9 cm − 7 cm = 2 cm
- Therefore, plant A grew the most, i.e. 5 cm, during the 2nd week.
- Growth of plant B during 1st week = 1 cm − 0 cm = 1 cm.
- Growth of plant B during 2nd week = 7 cm − 1 cm = 6 cm.
- Growth of plant B during 3rd week = 10 cm − 7 cm = 3 cm.
- Therefore, plant B grew the least, i.e. 1 cm, during the 1st week.
- At the end of the 2nd week, the heights of both plants were same.
