(1) x – y = 2 (x+y)2 = (x-y)2 + 4xy = 4 + 12 = 16 (x+y) = +/-4 Solving, x=3, y=1 or x=-1, y=-3 xy(x + y) = 12 or -12 INSUFFICIENT (2) x2 + y2 = 10 (x+y)2 = x2 + y2 + 2xy = 10 + 6 (x+y)2 = 16 (x+y) = +/-4 (x-y)2 = x2+y2-2xy = 10-6 = 4 x-y = +/-2 Solving, x=3, y=1 or x=-1, y=-3 or x=-3, y=-1 or x=1, y=3 xy(x + y) = 12 or -12 INSUFFICIENT Combining both statements, INSUFFICIENT Hence E. :)

'R' and 'S' scales are related in a linear fashion. Linear relationship can be defined by S = a*R But since they are not proportional, we introduce a constant 'b'. So S = a*R + b

You are right. The correct question is 5^x – 5^(x - 3) = (124)(5^y) Accordingly I have corrected the post.

Q6: A Lines 16 to 18 as well as lines 54 to 60 support the statement in 'A'. Q7 : B Lines 1 to 5, state that modern bankruptcy lwas focus on bankruptcy as a remedy for individuals and corporations in financial trouble. Thus creditors are not focus of these laws but they derive benefit because of the provisions of these laws. These lines therefore support 'B'. Q8 : A 'A' is correct because the author supports the modern laws several times in the passage. Q9 : E 'E' is correct because the author focuses on why changes in old bankruptcy laws were necessary, that led to modern bankruptcy laws. Q10 : A Lines 13 to 19 discuss the society's beliefs in favor of punishment for bankruptcy. 'A' is therefore correct. Q11 : B Since the author summarises his views in favor of modern bakruptcy laws in lines 54 to 60, 'B' is the best option that suitable to be included at the end of the passage. Q12 : D Lines 36 to 43 mention two reasons responsible for shift from punitive appoach to the modern approach. 'D' is supported by these lines. Q13 : D :)

'That' is a relative pronoun and starts an adjective clause which describes the noun 'Federal Reserve'.

Pronoun 'it' should refer to subject of previous clause i.e. 'stable interest rates'. However it is not possible here since 'it' is singular. Obviously 'it' refers to 'Federal Reserve'. In 'C' 'would' is not required where simple furture tense will be sufficient. In addition 'C' is wordy. :)

It is question no. 1

DEAR RAMBOPJ, Pls. use black color for questions. Thanks. :) 'Achievement of farm animals' in 'D' and 'E' well as 'achieving farm animals' in 'B' are unidiomatic phrases and confuse the meaning of sentence. 'As once' in 'A' is unidiomatic and fails to convey the correct meaning. It should be replaced by 'that was once'. 'C' is concise and grammatically correct. Hence C :)

Except 'E' all options end with the phrase 'lions playing in trees without telephoto lenses' or 'lions playing in trees without the aid of telephoto lenses' meaning thereby that the lions are playing without lenses which is wrong. Placement of 'without the aid of telephoto lenses', is correct only in 'E', thereby conveying correct meaning of the sentence. Hence E :)

Q1: (A) in the Federal Reserve keeping in control of inflation : 'Keeping in control of inflation' is awkward phrase.:INCORRECT (B) that the Federal Reserve will keep inflation under control : Concise and grammatically correct. :CORRECT © for the Federal Reserve, that it would keep control of inflation : 'It' does not have a proper reference.'Keep control of inflation' is awkward phrase. :INCORRECT (D) that inflation will be kept control of by the Federal Reserve : 'Kept control of' is unidiomatic. Unnecessary use of passive voice.:INCORRECT (E) that inflation would be kept control of by the Federal Reserve :'Kept control of' is unidiomatic. Use of 'would' as well as passive voice is unnecessary.:INCORRECT :)

Q2: (A) which a commoner or foreigner could not enter without any permission : 'Any' is redundant. 'Foreigner' should be preceded by 'a' for parallel construction. :INCORRECT (B) which a commoner or foreigner could enter without any permission only : Omission of 'not' changes meaning. 'Only' is unnecessary.:INCORRECT © which no commoner or foreigner could enter without permission : Concise and grammatically correct. :CORRECT (D) which, without permission, neither commoner or foreigner could only enter : Awkward and wordy construction. :INCORRECT (E) which, to enter without permission, neither commoner or foreigner could do :Awkward and wordy construction. :INCORRECT :)

Q11: Q1: If 5^x – 5^(x - 3) = (124)(5^y) 5^(x - 3){5^3 - 1} = 124*(5^y) 124*{5^(x - 3)} = 124*(5^y) 5^(x - 3) = 5^y y = (x - 3) Hence C Q2 : First employee can be assigned in 2 ways i.e. either to first or to second office. Similarly second and third employees can be assigned to any of the two offices. So total no. of ways = 2*2*2 = 8 Hence D Q3 : Let 30 = 6a + b and 60 = 24a + b Solving the two, a=5/3, b= 20 Let the required value on 'R-scale' is 'R'. 100 = R*a + b R = (100 - 20)/(5/3) = 48 Hence C Q4 : Integer n = 3a + 1 where 0 n 3a a Minimum value of a = 0, n=1 So 0 Hence C :)

That's excellent advice. I will try to follow it. Hope you will continue to post more such exercises. Thanks.

In 'A' and 'B' , 'exercise' and 'associated' are not parallel. In the correct choice, all the verbs should be parallel and in same tense. 'if calves exercise and associate with other calves, they require less medication and gain weight...... So 'they required' in 'C' and 'they have required' in 'D' are wrong verb tenses. 'E' is correct choice and uses parallel construction. :)

Q8 : C In para 1, the sentence 'They maintain that the sources ...................omitted the response of Asian settlers to this territory.' and again in para 2 'But because a full study of a culture's historical relationship to its land cannot confine itself to a narrow record ofexperience, these historiographers have begun to recognize the value of other kinds of evidence, such as the actions of Asian settlers.' These two sentences support choice 'C'. Q9 : E In para 2 'But because a full study of a culture's historical relationship to its land cannot confine itself to a narrow record ofexperience, these historiographers have begun to recognize the value of other kinds of evidence, such as the actions of Asian settlers.' indicates the primary purpose and choice 'E' is therefore consistent with it. Q10 : E In para 1 the lines 'In this endeavor historiographers examining the history of the Pacific Coast of the United States have traditionally depended on the records left by European American explorers of the nineteenth century who, as commissioned agents of the U.S. government, were instructed to report thoroughly their findings in writing.' support choice 'E'. Q11 :E In para 2 , 'But because a full study of a culture's historical relationship to its land cannot confine itself to a narrow record ofexperience, these historiographers have begun to recognize the value of other kinds of evidence, such as the actions of Asian settlers.' indicates that other kinds of evidences include, actions of Asian settlers. It means there are evidences other than actions of Asian sttlers and these evidences may not relate to immigration of non-Europeans. Therefore author may disagree with statement in 'E' Q12 : D In last para the lines 'Their vision was reinforced by specialized skills involving swamp reclamation and irrigation systems, which helped lay the foundation for the now well-known and prosperous agribusiness of the region.' indicate that their specialized skills led to foundation of modern agribusiness of region. But it does not mention that the chinese settlers initially possessed these skills. Other skills and knowledge are specifically mentioned in the passage. Hence 'D'. Q13 : B The lines 'Their vision was reinforced by specialized skills involving swamp reclamation and irrigation systems, which helped lay the foundation for the now well-known and prosperous agribusiness of the region.' in the last para are consistent with the observation in 'B'. Q14 : B In last para the lines 'Their vision was reinforced by specialized skills involving swamp reclamation and irrigation systems, which helped lay the foundation for the now well-known and prosperous agribusiness of the region. ' are consistent with 'B'. :)
