Question
Three statements are given followed by three
conclusions numbered I, II & Ill. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: Some dogs are tigers. All tigers are raincoats. Some raincoats are trucks. Conclusions: I. Some dogs are raincoats. Il. Some tigers are raincoats. IlI. Some trucks are raincoats.Solution
The possible Venn diagram is: 
Conclusions: Some dogs are raincoats. → Follows (As, Some dogs are tigers and All tigers are raincoats) Some tigers are raincoats. → Follows (As, All tigers are raincoats) Some trucks are raincoats. → Follows (As, Some raincoats are trucks Hence, the correct answer is (A).
