SBI Junior Associate 2015 · Question 129 of 200
arithmetic
Let population of village Q one year ago = $$x$$ => Population of village P one year ago = $$2x$$ => $$3528 = x (1 + \frac{20}{100})^2$$ => $$3528 = x (\frac{6}{5})^2$$ => $$x = \frac{3528 \times 25}{36} = 2450$$ $$\therefore$$ Present population of village P = $$2 \times 2450 = 4900$$
