Consider the following graphs. The curves in the graphs indicate different age groups in the populations of two countries A and B over a period of few decades :

Country A

Year	<15	15-64	64+
1950	0.2	0.35	0.05
1970	0.35	0.45	0.08
1990	0.32	0.8	0.1
2010	0.28	1.0	0.15
2030	0.25	0.95	0.25
2050	0.22	0.85	0.35

Years

<15     
15-64     
64+

Country B

Year	<15	15-64	64+
1950	0.15	0.2	0.05
1970	0.25	0.35	0.08
1990	0.32	0.55	0.1
2010	0.35	0.75	0.15
2030	0.32	1.0	0.25
2050	0.28	1.1	0.35

Years

<15     
15-64     
64+

With reference to the above graphs, which of the following are the most logical and rational inferences that can be made?

1. Over the last two and a half decades, the dependency ratio for country B has decreased.
2. By the end of next two and a half decades, the dependency ratio of country A will be much less than that of country B.
3. In the next two decades, the workforce relative to its total population will increase in country B as compared to country A.
