The bar chart give
The percent increase in population from 1991 to 2001 is:
= 68.40 - 54.80
= 13.6 crores
The bar chart give
The percent increase in population from 1991 to 2001 is:
Solution:
Increase in Population= 68.40 - 54.80
= 13.6 crores

In which census year, the per cent increase in population is highest as compared to that in the previous census year?
The bar chart give
In which census year, the per cent increase in population is highest as compared to that in the previous census year?

3. Study the graph and answer the questions:
The bar chart give
In which census year, the per cent increase in population is least as compared to that in the previous census year?
= [(36.14 × 31.85) × 100]
= 13.47% least in all
The bar chart give
In which census year, the per cent increase in population is least as compared to that in the previous census year?
Solution:
% increase in 1971= [(36.14 × 31.85) × 100]
= 13.47% least in all
4. Study the graph and answer the questions:
The bar chart give
Per year increase in population from the year 1951 to 2001 is
= 68.40 - 27.90
= 40.5 crores
Hence, annual increase
The bar chart give
Per year increase in population from the year 1951 to 2001 is
Solution:

Hence, annual increase
5. Study the graph and answer the questions:
What was the increase in registration of vehicles other than Cars from January to April 1991?
= 27 - 21
= 6 thousand
No. of other vehicles registered in April 1991
= 35 - 20
= 15 thousand
Hence, increased
= 15 - 6
= 9 thousand
What was the increase in registration of vehicles other than Cars from January to April 1991?
Solution:
No. of other vehicles registered in January 1991= 27 - 21
= 6 thousand
No. of other vehicles registered in April 1991
= 35 - 20
= 15 thousand
Hence, increased
= 15 - 6
= 9 thousand

= 18 is maximum in all.
8. Study the graph and answer the questions:
What was the number of vehicles other than Cars registered in March, 1991?
= 25 - 15
= 10 thousand
What was the number of vehicles other than Cars registered in March, 1991?

10. : Purana and Naya two brand of mixer-grinder available in the market. Purana was introduced in 1990 and Naya was introduced in 1997. For both brands, 20% of the mixer-grinder bought in a particular year are disposed off as junk exactly two year later. It is known that 10 Purana mixer-grinder were disposed off in 1997. The following chart show the operation from 1995 to 2000, as at end of the year.
How many Naya mixer-grinder disposed off by end of 2000 ?
Then, In 2000, 20% of 50 disposed off = 10.
Similarly, number of mixer grinder purchased in 1997 is 25.
Number of mixer-grinder disposed in 1999 = 20% of 25 = 5.
Total number of mixer-grinder disposed off at end of 2000
= 10 + 5
= 15
How many Naya mixer-grinder disposed off by end of 2000 ?
Solution:
In the year 1998, (75 - 25) = 50 mixer-grinder purchased.Then, In 2000, 20% of 50 disposed off = 10.
Similarly, number of mixer grinder purchased in 1997 is 25.
Number of mixer-grinder disposed in 1999 = 20% of 25 = 5.
Total number of mixer-grinder disposed off at end of 2000
= 10 + 5
= 15
