Question
Statements: Some cost are amount. At
least some amount are interest. 100% interest are principle. Only cost are compound. Conclusions: I. Some amount are compound. II. Some principle are amount. III. Some cost are principle. In the question below there are four statements followed by three conclusions I, II and III. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the four statements disregarding commonly known facts.Solution
Only cost are compound → All compound are cost and compound cannot have any positive relation with any element. Hence conclusion I does not follow. At least some amount are interest (I) + 100% interest are principle (A) → Some amount are principle (I) → Conversion → Some principle are amount (I). Hence conclusion II follows. Some cost are amount (I) + At least some amount are interest (I) → No conclusion. Hence conclusion III does not follow.
