D Correct answer
Explanation

Uttar Pradesh = 150 lakh. Rajasthan = 80% of UP = 0.8 * 150 = 120 lakh. This 120 lakh is the current population after a 20% increase. Previous population = 120 / 1.2 = 100 lakh.

AI explanation

The population of Uttar Pradesh is given as 150 lakh. Since the population of Rajasthan is 80 percent of the population of Uttar Pradesh, the current population of Rajasthan is 80 percent of 150, which equals 120 lakh. If this current population represents a 20 percent increase from the previous record, we divide 120 lakh by 1.20 to find the previous record. The previous population of Rajasthan was 100 lakh.
