• Question 5 of 5 5. Question 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. a) If the data either in I or II alone are sufficient to answer the question. b) If the data even in both the statements together are not sufficient to answer the question. c) If the data in both the statements together are needed. d) If the data in statement I alone are sufficient to answer the question. Correct Answer: A Explanation From I, we find that the weight of one pole is (5 x 4) i.e. 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 So, weight of 10 poles = 20 kg So, weight of 10 poles = 200 kg. Thus, II alone is also sufficient. Incorrect Answer: A Explanation From I, we find that the weight of one pole is (5 x 4) i.e. 20 kg and so the weight of 10 poles is 200 kg. thus, I alone is sufficient.

#### 5. Question
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.
• a) If the data either in I or II alone are sufficient to answer the question.
• b) If the data even in both the statements together are not sufficient to answer the question.
• c) If the data in both the statements together are needed.
• d) If the data in statement I alone are sufficient to answer the question.
Explanation
From I, we find that the weight of one pole is (5 x 4) i.e. 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
So, weight of 10 poles = 20 kg
So, weight of 10 poles = 200 kg.
Thus, II alone is also sufficient.
