5% of the population of a town were kilked in an earthquake and 8% of the reaminig left the town.if the population of town is 43700 what is the population in the beginning .

Answer 1

Let total population of town at  starting = 100%
population of a town were kilked in an earthquake= 5%

population remain after earthquake = 95%

population remain after leaving the town = 95 * 92 = 8740/100 = 87.4

87.4% equals to 43700
1% equal to 43700/87.4 = 500
100% equals to = 500*100 = 50,000
