In a village, 30% of the villagers belong to upper economic class. The number of villagers who belong to middle economic class are 3/2 of the number of villagers who belong to lower economic class. If 6860 villagers belong to lower economic class, what is the population of the village ?1). 226002). 245003). 260004). 25500

Answer»

Solution

Let the TOTAL population of village = $100x$

Population of upper economic class = $\frac{30}{100} \TIMES 100x = 30x$

Population of lower economic class = $6860$

Population of middle economic class = $\frac{3}{2} \times 6860 = 10,290$

=> Population of middle and lower economic class

= $100x - 30x = 6860 + 10290$

=> $70x = 17150$

=> $x = \frac{17150}{70} = 245$

$\therefore$ Total population = 100 * 245 = 24500
