15 % people of a village in sri lanka died by bombardment , 25 % of the remainder left the village on account of fear . if now the population is reduced to 4555 , how much was it in the beginning ?
"x * ( 85 / 100 ) * ( 75 / 100 ) = 4555 x = 7145 answer : b"
floor(divide(4555, multiply(divide(subtract(const_100, 15), const_100), divide(subtract(const_100, 25), const_100))))
