What will be the total weight of 10 poles, each of the same weight?

I. One-fourth of the weight of each pole is 5 kg.

II. The total weight of three poles is 20 kilograms more than the total weight of two poles.


A) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question

B) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question

C) if the data either in statement I alone or in statement II alone are sufficient to answer the question

D) if the data given in both statement I and II together are not sufficient to answer the question

E) if the data in both statements I and II together are necessary to answer the question

Answer:

Option C

Explanation:

From I, we conclude that weight of each pole = (4 x 5) kg = 20 kg. So, total weight of 10 poles = (20 x 10) kg = 200 kg.

From II, we conclude that:  Weight of each pole = (weight of 3 poles) - (weight of 2 poles) = 20 kg.

So, total weight of 10 poles = (20 x 10) kg = 200 kg.
