State the type of the bar graph.
How much percent is the Tur production to total production in Ajita’s farm?
Compare the production of Gram in the farms of Yash and Ravi and state whose percentage of production is more and by how much?
Whose percentage production of Tur is the least?
State production percentages of Tur and Gram in Sudha’s farm.

The given graph is a percentage bar graph.
Percent of tur production to the total production in Ajita’s farm is 60%.
Production of Gram in the farm of Yash = 50%
Production of Gram in the farm of Ravi = 30%
∴ Difference in the production = 50% – 30% =20%
∴ Yash’s production of Gram is more and by 20%.
Sudha’s percentage production of Tur is the least.
Production percentages of Tur and Gram in Sudha’s farm are 40% and 60% respectively.
