Statements:Some pins are needles. All needles are
ropes. Some ropes are buckets. All buckets are trees. Conclusions:I. Some buckets are pins. II. Some ropes are pins. III. No bucket is pin. In each question below are given four statements followed by three conclusions numbered I, II and III. You have to take the two given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known factsSolution
Some pins are needles(I) + All needles are ropes(A) ⇒ Some pins are ropes(I) + Some ropes are buckets(I) ⇒ No conclusion. Hence conclusion I & III do not follow but they will make complementary pair. Hence, either conclusion I or III follows. Some pins are needles(I) + All needles are ropes(A) ⇒ Some pins are ropes(I) ⇒ Conversion ⇒ Some ropes are pins(I). Hence, conclusion II follows.
