Question: 300 cows in a field are made up of male and female cows. There are twice as many females as males. Half the females are spotted, and half the males have horns. How many more females with spots are there than males with horns? Think carefully first, then make a decision:
There are (300 / 3) x 2 = 100 x 2 = 200 females cows in the field. There are 200 / 2 = 100 male cows in the field. 200 / 2 = 100 female cows are spotted. 100 / 2 = 50 male cows have horns. There are 100 - 50 = 50 more females with spots than males with horns. So the answer is 50.
