Answers & Solutions:
1) Answer (D)
Some exams are tests and no exam is a question.
Nothing can be built between tests and questions from this information.
Some exams are tests doesn’t mean some tests are not exams because this could be a case where all tests are exams.
Hence neither of the statements is true.
2) Answer (B)
All forces are energies and all energies are powers => all forces are powers. => conclusion 1 is wrong
No power is a heat and all forces are powers => No heat is force.
Only conclusion 2 follows.
3) Answer (A)
All forces are energies, all energies are powers and no power is heat => no energy is heat => Conclusion 1 is correct
No force is heat => Conclusion 2 is wrong.
Hence only conclusion 1 follows.
4) Answer (E)
All plastics are notes and no note is a coin => no coin is plastic => Conclusion 1 follows.
Some coins are metals => Some notes being metals is a possibility => All plastics being metals is a possibility => Conclusion 2 follows.
=> Both follow
5) Answer (D)
No plastic is a coin and some coins are metals => Some metals being a plastic is a possibility => Conclusion 1 is wrong
All plastics are notes does not imply all notes are plastic => Conclusion 2 is wrong
Hence neither of the conclusions is correct
6) Answer (E)
All symbols are graphics and some symbols are figures => some graphics are figures => conclusion 1 follows
All symbols are graphics and no graphic is a picture => no symbol is a picture => conclusion 2 follows
=> Both conclusions follow
7) Answer (B)
Only some jobs are occupations => conclusion 1 is wrong
It is possible that all occupations are vacancies => conclusion 2 is correct
Therefore only 2 follows
8) Answer (C)
Using the Venn diagrams, the statements 1 and 2 are implied.
9) Answer (E)
From the statements, we can draw a venn diagram as follows. Hence, statement II is definitely not true.
As some papers are files, some certificates are definitely files. Hence, statement III is true.
Statement I and IV are mutually exclusive and collectively exhaustive. Hence, either I or IV is true.
Thus, statement III and either I or IV follow. Hence, the answer is none of the above.
10) Answer (A)
As per the Venn diagram alongside, only conclusion II follows.
11) Answer (E)
As per the Venn diagram alongside, both conclusions 1 and 3 follow.
12) Answer (B)
All letters are scores and all scores are characters. So, some characters are definitely letters.
The other three conclusions do not necessarily follow. So, option b) is the correct answer.
13) Answer (E)
Some casual are formal.
All formal are expensive. Hence, some casuals are expensive.
All expensive are elegant. Hence, all formals are elegant and some casuals are elegant.
Therefore, both I and II follow.
14) Answer (A)
The data can be intrepreted in syllogisms form as:
Some red are paints.This conclusion can be drawn as apparent from Venn diagram.
All red are roses.This is obviously a wrong conclusion.
Hence, only I follows.
15) Answer (D)
The data can be intrepreted in Venn diagram from as:
Some towns are rural. We cannot say this with surety and this conclusion can be contradicted.
All rural are towns.This definitely cannot be concluded from Venn diagram.
Hence, both conclusion I and II do not follow.
16) Answer (D)
Data can be intrepreted in Venn diagram form as:
Some tablets are bitter. This conclusion cannot be drawn from the Venn diagram.
No medicines is a tonic.This conclusion also cannot be drawn.
Both I and II do not follow.
Option D is correct option.
17) Answer (B)
Data can be intrepreted in Venn diagram form as:
Some incomes are tangible. The income and tangibles are disjoint sets. Hence, conclusion drawn is incorrect.
At least some perks are salaries. This conclusion is correct. There is intersection betweem perks and salaries set.
18) Answer (A)
The data in Venn diagram format can be intrepreted as:
Some flowers are colours. This conclusion can be drawn as there is intersection between Flowers and Colours set.
All flowers can be colors. In a similar way all petals can be colors. Hence, only conclusion I follows.
19) Answer (D)
Some tables are big. This conclusion cannot be drawn. Big and Tables is disjoint set.
No desk is a drawer. This conclusion also cannot be drawn with surety as there might be intersection between Drawers and Desks
Both I and II do not follow.
20) Answer (B)
The data can be intrepreted in Venn diagram form as:
Some colleges are strong.We cannot draw this conclusion with assurance.
At least some strong are concrete. This conclusion can be drawn with surety as apparent from Venn diagram.
Only II follows. Option B is correct.
