Problem: in a school of 450 boys , 44 % of muslims , 28 % hindus , 10 % sikhs and the remaining of other communities . how many belonged to the other communities ?
Rationale: "44 + 28 + 10 = 82 % 100 – 82 = 18 % 450 * 18 / 100 = 81 answer : d"
annotated_formula: divide(multiply(450, subtract(const_100, add(add(44, 28), 10))), const_100)
