- The infant mortality rate in Jharkhand is 11.3 per 1000 births. This means for every 1000 children born, 11.3 children die.
- The number of deaths is given as 452. Using the formula:
\[ \text{Number of deaths} = \frac{11.3}{1000} \times \text{Total number of births} \]
Let the total number of births be x. Since the number of deaths is 452:
\[ 452 = \frac{11.3}{1000} \times x \]
Solving for x:
\[ x = \frac{452 \times 1000}{11.3} \] \[ x = \frac{452000}{11.3} = 40,000 \]
Thus, the total number of births is 40,000.
Conclusion: The correct answer is (d) 40,000.
The plots below depict and compare the average monthly incomes (in Rs. ’000) of males and females in ten cities of India in the years 2005 and 2015. The ten cities, marked A-J in the records, are of different population sizes. For a fair comparison, to adjust for inflation, incomes for both the periods are scaled to 2025 prices. Each red dot represents the average monthly income of females in a particular city in a particular year, while each blue dot represents the average monthly income of males in a particular city in a particular year. The gender gap for a city, for a particular year, is defined as the absolute value of the average monthly income of males, minus the average monthly income of females, in that year.
