Rural Families and Agricultural Labourers

Introduction:
Rural families play a crucial role in the agricultural sector, contributing significantly to the country's food production. In this question, we are asked to determine the proportion of rural families who work as agricultural laborers.

Analysis:
To find the answer, let's consider each option and evaluate its accuracy:

- Option a) 3/4th: This implies that 75% of rural families are agricultural laborers. However, this figure seems too high, as not all rural families are involved in agricultural activities.
- Option b) 2/5th: According to this option, 40% of rural families work as agricultural laborers. This seems more reasonable and aligns with the fact that a significant proportion of rural families engage in agricultural work.
- Option c) 2/3th: This suggests that 66.67% of rural families are agricultural laborers. While this figure is plausible, it is slightly higher than option b) and may overestimate the actual proportion.
- Option d) 1/5th: This implies that only 20% of rural families are agricultural laborers. This figure appears to be too low, considering the importance of agriculture in rural areas.

Conclusion:
Based on the analysis, option b) 2/5th is the most accurate answer. It signifies that 40% of all rural families work as agricultural laborers. This proportion reflects the significant contribution of rural families to the agricultural sector and highlights the crucial role they play in sustaining food production in the country.
