Study the given pie-chart and answer the question that follows.
The pie-chart shows the percentage of the population in five villages in a year.
Total Population of five villages = 50,000.
Find the ratio of population in villages B and D.
Find the fourth proportional to (a + b)2× (a3 - b³), (a3 + b3), (a² - b²).
\(\frac{a^{2}-ab+b^{2}}{a+b}\)
\(\frac{a^{2}+ab+b^{2}}{a-b}\)
\(\frac{a^{2}-ab+b^{2}}{a^{2}+ab+b^{2}}\)
\(\frac{a^{2}+ab+b^{2}}{a^{2}-b^{2}}\)
