What will be the total weight of 10 poles each of the same weight ?
I. One-fourth of the weight of a pole is 5 kilograms.
II. The total weight of three poles is 20 kilograms more than the total weight of two poles.
Answer & Explanation
C) If the data either in I or II alone are sufficient to answer the question;
From I, we find that the weight of one pole is (5 x 4) = 20 kg ,and so the weight of 10 poles is 200 kg.
Thus, I alone is sufficient.
From II. we have : (weight of 3 poles — weight of 2 poles) -= 20 kg or weight of one pole - 20 kg.
So. weight of 10 poles 200 kg.
Thus. II alone is also sufficient
