in a school of 300 boys , 44 % of muslims , 28 % hindus , 10 % sikhs and the remaining of other communities . how many belonged to the other communities ?
"44 + 28 + 10 = 82 % 100 – 82 = 18 % 300 * 18 / 100 = 54 answer : a"
divide(multiply(300, subtract(const_100, add(add(44, 28), 10))), const_100)
