Question
Statements: Â Â Â Â Â Â Some wires are widths.
>Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â No width is a length. Conclusions: Â Â Â Â Â Â I. No length is a wire. II. Some wires are lengths. In each question below are given two statements followed by two conclusions numbered I and II. 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 facts. Give Answer:Solution
Some wires are widths (I) + No width is a length (E) = Some wires are not lengths (O). Hence, neither conclusion I nor II will follow. However, Conclusion I and II make a complementary pair, hence, either conclusion I or II will follow.
The average of three numbers a, b and c is 2 more than c. The average of a and b is 48. If d is 10 less than c, then the average of c and d is:
