Correct Answer: 106.25 crore

Solution : As per the given bar graph:
The total population in 1981 = 35 + 33 = 68 crore
The total population in 1991 = 44 + 41 = 85 crore
Total increase in population from 1991 to 1981 = 85 – 68 = 17 crore
Percentage increase = $\frac{\text{Total increase in population}}{{\text{The total population in 1981}}}×100$
Percentage increase = $\frac{\text{17}}{{\text{68}}}×100=25\%$
So, total population in 2001 = 125% of 85 crore
= $\frac{85×125}{100}$
= 106.25 crore
Hence, the correct answer is 106.25 crore.
