Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Statements:

A. Some dogs are goats.

B. All goats are peacocks.

C. All peacocks are eagles.

Conclusions:

I. Some peacocks are dogs.

II. All dogs are peacocks.

III. All eagles are peacocks.

  • AOnly conclusion I follows
  • BOnly conclusions II and III follow
  • COnly conclusions I and II follow
  • DAll the conclusions, I, II and III, follow
Correct answer: A

Explanation

Some dogs are goats and all goats are peacocks, so some dogs are peacocks, and hence some peacocks are dogs (I follows). Nothing is said about all dogs (II fails) and the converse of ‘All peacocks are eagles’ is not valid (III fails). Only I follows.
