6. The number of tigers in India went down drastically between 1900
and 1970. ‘Project Tiger’ was launched in 1973 to track and protect
tigers in India. Starting in 2006, the exact number of tigers in India
was tracked. Nagma and Shreya looked up information about the Case study
number of tigers in India between 2006 and 2022 at 4-year intervals
and prepared a table as shown below.

Year 2006 2010 2014 2018 2022
Number of Tigers 1,411 1,706 2,226 2,967 3,682

They estimated the number of tigers to the nearest hundred and presented this data in a bar
graph.

But there are a few mistakes in the graph.
(a) Try to find those mistakes and fix them.
(b) In which 4-year interval do you see the maximum growth in the number of tigers?

(c) Approximately how many times was the population of tigers increased from 2006 to 2022?
7. The gold rate varies on day to day basis. Here is the 22 Ct/g Gold rate in the Delhi.
