This question compares gender-based earning differences across different employment categories (casual work, self-employment, and regular/salaried work) in urban and rural India. Let's assess each option on its own merits.
Ruling out A, C and D on these grounds leaves self-employment as the category with the most pronounced, well-documented gender earnings disparity in urban India.
Therefore, the correct answer is Men's average earning in urban areas in self-employment is nearly 2.5 times that of earnings of women.
The question asks by what percentage a non-SC/ST worker's earnings in regular/urban employment exceed those of a SC/ST worker. Let's weigh each of the four ranges.
Weighing the four ranges against how regular employment earnings actually diverge by social group, the 30-35% band fits best.
Therefore, the correct answer is Between 30% and 35%.
This question uses the simple interest relationship to compare how long it takes two different starting amounts, growing at the same rate, to reach the same final value. Let the SC/ST worker's average casual earnings be \( P \). Based on the earnings gap for casual employment, a man's average casual earnings work out to about \( 1.122P \), a comparatively modest gap next to the far larger disparity seen in self-employment.
Using the simple interest formula \( A = P\left(1 + \dfrac{rt}{100}\right) \), for the man over 20 years at 16% per annum:
\[ A = 1.122P\left(1 + \dfrac{16 \times 20}{100}\right) = 1.122P \times 4.2 = 4.712P \]For the SC/ST worker, depositing \( P \) for \( t \) years at the same 16% rate to reach the same amount \( A \):
\[ 4.712P = P\left(1 + \dfrac{16t}{100}\right) \]Dividing both sides by \( P \):
\[ 4.712 = 1 + 0.16t \implies 0.16t = 3.712 \implies t = \dfrac{3.712}{0.16} = 23.2 \]Therefore, the correct answer is 23.2 years.
This question asks for the difference between the number of women in India's labour force in 2004-05 and in 2020-21, using the LFPR percentages and the 2020-21 population figure given in the passage.
Women's population in 2020-21 = 670 million, which is 24% more than in 2004-05, so:
\[ \text{Women's population in 2004-05} = \dfrac{670}{1.24} \approx 540.3 \text{ million} \]Number of women in the labour force in 2020-21 (25.1%):
\[ 0.251 \times 670 \approx 168.2 \text{ million} \]Number of women in the labour force in 2004-05 (42.7%):
\[ 0.427 \times 540.3 \approx 230.7 \text{ million} \]Difference:
\[ 230.7 - 168.2 \approx 62.5 \text{ million} = 6.25 \text{ crore} \]Therefore, the correct answer is Between 6 and 8 crores.
This question asks for the ratio of females to males aged 15 and above who hold regular salaried or self-employed jobs, given the population and participation percentages in the passage. Let the total female population be \( F \), so the total male population is \( 1.05F \).
Males aged 15+ = \( 0.76 \times 1.05F = 0.798F \); Females aged 15+ = \( 0.72F \).
Of these, 60% of males 15+ hold regular salaried/self-employed jobs, and 19% of females 15+ do:
\[ \text{Males employed} = 0.60 \times 0.798F = 0.4788F \]\[ \text{Females employed} = 0.19 \times 0.72F = 0.1368F \]Ratio of females to males employed:
\[ \dfrac{0.1368F}{0.4788F} = \dfrac{0.1368}{0.4788} = \dfrac{2}{7} \]Therefore, the correct answer is 2 : 7.
