There are five sheeps in a house, each of them with same weight.
What is the total weight of those 5 sheeps?
I. Half of a sheep weighs 20Kg.
II. Sum of the weight of 3 sheeps is equal to 40Kg more than sum of 2 sheeps weight.
From I, we find that the weight of one sheep is 40kg and so the weight of 5 sheeps is 200 kg.
Thus I alone is sufficient.
From II we have weight of one sheep is 40kg, so weight of 5 sheeps is 200 kg.
Thus II alone is also sufficient.
