  • (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

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

Statements:

  1. One-fourth of the weight of each pole is 5 kg.
  2. The total weight of three poles is 20 kilograms more than the total weight of two poles.

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient
Both I and II are sufficient
Answer: Option
Explanation:

From I, we conclude that weight of each pole = (4x5) 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 pojes = (20 x 10) kg = 200 kg.

St2: Wt of 3 poles = 20 kgs + wt of 2 poles.
wt of 3 poles - wt of 2 poles = 20,
wt of 1 pole = 20kgs,
finally , wt of 10 poles = 10 * 20 = 200 kgs.

Ans is both st1, st2 are sufficient.

For the second point, main point to look for is the weight of each pole are same, so the weight of 3 poles is more than the weight of two poles, it means they are giving the weight of each pole which is same, 20.

In statement I, what if the weight of the pole is not uniform throughout?

I mean: what if the total weight of the pole is not 4x5? There is a chance that the pole is tapered! Right?

Please correct me, If I am wrong.
