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 from the statements Statements: All ducks are tigers. All tigers are monkeys. All monkeys are cows. Conclusions: I. All tigers are cows. II. All monkeys are ducks. III. All ducks are cows. IV. All cows are tigers. Correct Answer Both conclusions I and III follow. Statements: All ducks are tigers. All tigers are monkeys. All monkeys are cows. The least possible diagram for the given statements is as follows [ alt="F1 Savita Railways 04-7-22 D35" src="//storage.googleapis.com/tb-img/production/22/07/F1_Savita_Railways_04-7-22_D35.png" style="width: 238px; height: 167px;"> Conclusions: I. All tigers are cows → True (As all tigers are monkeys and all monkeys are cows so all tigers are also cows) II. All monkeys are ducks → False (As all ducks are tigers and all tigers are monkeys so all ducks are monkeys not all monkeys are ducks) III. All ducks are cows → True (As all ducks are tigers, all tigers are monkeys and all monkeys are cows so all ducks are also cows) IV. All cows are tigers → False (As all tigers are monkeys and all monkeys are cows so all tigers are cows not all cows are tigers) Hence, “Both conclusions I and III follow” is the correct answer.
