Answers & Solutions   1 .     Answer : Option B Explanation : Statement (A) + Statement (B) gives the conclusion “Some dogs are tree” [I + A = I]. Now conversion of “Some dogs are trees” gives conclusion I. Hence, I follows. But conclusions II and IV do not follow. Conversion of statement (A) gives the conclusion “Some rats are dogs”. Hence, conclusion III does not follow. 2 .     Answer : Option D Explanation : Statement (A) + Statement (B) gives the conclusion “Some boys are clouds [I + A = I] on conversion “Some louds are boys”. Hence, conclusion I follows. Now, “Some boys are clouds” + Statement (C) gives no conclusion [ I + I = no conclusion] . Hence, conclusion II does not follow. Statement (B) + Statement (C)gives no conclusion [A + I = no conclusion] . Hence, conclusion III does not follow. But conclusion IV follows from statement (A). 3 .     Answer : Option A Explanation : Statement (A)+Conversion of statement (B) (“Some flowers are houses”) gives no conclusion [A + I = no conclusion]. Hence, conclusion I does not follow. Statement (C) + Statement (B) gives no conclusion (A + I = no conclusion). Hence, conclusion II and IV do not follow. But these two conclusions make a complementary pair (IE- type). Hence, conclusion, either II or IV follows. Conclusion III follows from conversion of statement (A). 4 .     Answer : Option D Explanation : Only I, II and III follow. Statement (A)+ Statement (B) gives conclusion I [A + E = E]. Hence, conclusion I follows but conclusion I V does not follow. Conclusion II follows from conversion of statement (C). Similarly, conclusion III follows from conversion of statement (A). 5 .     Answer : Option B Explanation : Conversion of statement ( C) gives conclusion I. Similarly, conversion of statement (A) gives conclusion II. Statement (A) + Statement (B) gives no conclusion [I + I = No conclusion]. Hence conclusion III does not follow. Similarly, statement (B) + statement (C) gives no conclusion [I + I = No conclusion]. Therefore, conclusion IV does not follow. 6 .     Answer : Option C Explanation : Step II: 765 42 183 289 542 65 110 350 Step III: 765 42 542 183 289 65 110 350 Step IV: 765 42 542 65 183 289 110 350 7 .     Answer : Option D Explanation : Input: 239 123 58 361 495 37 Step I: 495 239 123 58 361 37 Step II: 495 37 239 123 58 361 Step III: 495 37 361 239 123 58 8 .     Answer : Option D Explanation : Input: 39 88 162 450 386 72 29 Step I: 450 39 88 162 386 72 29 Step II: 450 29 386 39 88 162 72 Step III: 450 29 386 39 162 88 72 Step IV: 450 29 386 39 162 72 88 Step V: 450 29 386 39 162 72 88 9 .     Answer : Option A Explanation : Last step can be known directly. 10 .     Answer : Option B Explanation : Step I: 785 198 32 426 373 96 49 Step II: 785 32 198 426 373 96 49 Step III: 785 32 426 198 373 96 49 Step IV: 785 32 426 49 198 373 96
