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 |
