# Verbal Reasoning - Data Sufficiency - Discussion

### Discussion :: Data Sufficiency - Section 1 (Q.No.2)

In each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and

• (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 statements I and II together are not sufficient to answer the question and
• (E) If the data in both statements I and II together are necessary 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.

 [A]. I alone is sufficient while II alone is not sufficient [B]. II alone is sufficient while I alone is not sufficient [C]. Either I or II is sufficient [D]. Neither I nor II is sufficient [E]. Both I and II are sufficient

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.

 Saurabh said: (Sep 1, 2011) Answer should be both I and II are sufficient.

 Senthil said: (Apr 4, 2012) I need explanation of Statement II Weight of each pole = (weight of 3 poles) - (weight of 2 poles) = 20 kg.

 Harry said: (Nov 30, 2012) Explanation for statement II: Let the weight of one pole be x So x + x = a ( a is weight of two poles & each pole is of same weight) i.e 2x = a Similarly 3x = a + 20 ( total weight of three poles is 20 kilograms more than the total weight of two poles) i.e 3x - 20 = a So 2x = 3x - 20 x = 20.

 Ponmuneeswariganesan said: (Jan 5, 2014) Is any technique is available to solve the data sufficiency problems?

 Eswar said: (Jan 8, 2014) Any new methods for solving these questions?

 Riya said: (Oct 12, 2015) Similarly 3x = a + 20 (Total weight of three poles is 20 kilograms more than the total weight of two poles). i.e 3x-20 = a. So 2x = 3x-20. x = 20. I am not clear with this step and what is the meaning of total weight of three poles is 20 kilograms more than the total weight of two poles.

 Shahid said: (Sep 3, 2016) Statement one is alone to solve this. Logically if 1/4 of weight is 5 Kg then obviously 4/4 is 20 kg. So 20 kg is the weight of one pole then 200 kg is the weight of 10 poles.

 Suman Raj said: (Dec 11, 2016) From both I and II, we find that the weight of 10 poles. So, the answer should be both I and II are sufficient.

 Durgesh said: (Dec 12, 2016) Answer should be both I and II are sufficient.

 Priya said: (Jan 31, 2017) Can you please explain the equation : Similarly 3x = a + 20 ( total weight of three poles is 20 kilograms more than the total weight of two poles).

 Shekhar Patel said: (Feb 6, 2017) According to me, the answer is both l and ll are sufficient.

 Abhishek Singh said: (May 5, 2017) The Answer should be both I and II are sufficient.

 Subhasmita Jena said: (Jul 11, 2017) The answer should be both l and ll statement.

 Dattu said: (Feb 22, 2018) 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.

 Abhishek Kumar said: (Jun 28, 2018) 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.

 Ram Krishna said: (Aug 4, 2018) The Answer should be E.

 Rohit Patil said: (Sep 17, 2018) The should be Both I and II are sufficient.

 Parth said: (Oct 30, 2018) 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.

 Sheetal said: (Sep 3, 2020) The answer should be 1 and 2 are sufficient. Someone, please explain to me in detail.

 Pradyumna11 said: (Sep 25, 2020) Nice, thanks @Dattu.

 Vinay said: (Jan 3, 2021) Here we are not combining both statements. Option C is right because by reading each statement individually we can conclude. Option E is only correct when we use two statements together to conclude.

 Hemalatha said: (Jan 22, 2021) Option (A). 1/4 of each pole weight = 5 kg. Then 1 pole weight = 5*4= 20 kg. 1 pole weight is = 20 kg. Then 10 poles weight= 10 pole*20 kg. That is = 200 kg.

 Tanishq said: (May 1, 2021) The abswer should be E.
