3 men and 8 women complete a task in same time as 6 men and 2 women do . how much fraction of work will be finished in same time if 4 men and 5 women will do that task .
3 m + 8 w = 6 m + 2 w 3 m = 6 w 1 m = 2 w therefore 3 m + 8 w = 14 w 4 m + 5 w = 13 w answer is 13 / 14 answer : a
divide(add(multiply(divide(subtract(8, 2), subtract(6, 3)), 4), 5), add(multiply(6, divide(subtract(8, 2), subtract(6, 3))), 2))
