🔢 Step-by-Step Solution

Identify approximate populations from Census 2011

Extract the approximate population counts: Bihar $\approx 10.41$ crore, West Bengal $\approx 9.13$ crore, Madhya Pradesh $\approx 7.26$ crore, and Rajasthan $\approx 6.85$ crore.

Bihar>West Bengal>Madhya Pradesh>Rajasthan\text{Bihar} > \text{West Bengal} > \text{Madhya Pradesh} > \text{Rajasthan}Bihar>West Bengal>Madhya Pradesh>Rajasthan

Convert counts to percentage share

Since total population of India is constant at $\approx 121.08$ crore, comparing raw numbers is equivalent to comparing percentage shares.

10.41121.08>9.13121.08>7.26121.08>6.85121.08\frac{10.41}{121.08} > \frac{9.13}{121.08} > \frac{7.26}{121.08} > \frac{6.85}{121.08}121.0810.41​>121.089.13​>121.087.26​>121.086.85​

Determine descending order

Arrange the states based on the values calculated in the previous step to confirm the descending order.

Bihar(8.60%)>West Bengal(7.54%)>Madhya Pradesh(6.00%)>Rajasthan(5.66%)\text{Bihar} (8.60\%) > \text{West Bengal} (7.54\%) > \text{Madhya Pradesh} (6.00\%) > \text{Rajasthan} (5.66\%)Bihar(8.60%)>West Bengal(7.54%)>Madhya Pradesh(6.00%)>Rajasthan(5.66%)
