Question 25

Assuming that the rate of increase in the total population in India during 1991-2001 remains the same as that was during the period 1981-1991, estimate the total population in India in 2001.

Solution

Total population in 1981 = 35 + 33 = 68

Total population in 1991 = 44 + 41 = 85

% increase in population = $$\frac{85-68}{68} \times 100$$

= $$\frac{100}{4}=25\%$$

$$\therefore$$ Total population in 2001 = $$85 \times \frac{125}{100}$$

= $$85 \times 1.25 = 106.25$$ crores

=> Ans - (B)
