in the recent , climate conference in new york , out of 700 men , 500 women , 800 children present inside the building premises , 20 % of the men , 40 % of the women and 10 % of the children were indians . find the percentage of people who were not indian ?
solution : number of indians men present there = 700 * 20 / 100 = 140 indian women = 500 * 40 / 100 = 200 indian children = 800 * 10 / 100 = 80 . total member present in climate conference = 700 + 500 + 800 = 2000 total indian = 200 + 140 + 80 = 420 hence , % of indian present there = 420 * 100 / 2000 = 21 % % of people who were not indian = 100 - 42 = 79 % . answer c
multiply(divide(add(add(multiply(700, subtract(const_1, divide(20, const_100))), multiply(500, subtract(const_1, divide(40, const_100)))), multiply(800, subtract(const_1, divide(10, const_100)))), add(add(700, 500), 800)), const_100)
