Direction (Q. 1 - 5) : In each question below, there are four statements followed by four conclusions numbered I, II, III and IV. You have to take the 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 follow(s) from the given statements.
Statements: a. Some books are pens.
b. All pens are pencils.
c. No pencils are copies.
d. Some copies are not calculators.
Conclusions: I. Some books are not calculators.
II. No books are copies.
III. No pens are copies.
IV. Some pencils are not copies.
Statements: a. All books are tables.
b. All books are chairs.
c. No copies are chairs.
d. All chairs are stools.
Conclusions: I. Some copies are tables.
II. All books are stools.
III. Some stools are not tables.
IV. All tables are stools.
Statements: a. No cops are police.
b. All police are humans.
c. All humans are politicians.
d. No politicians are doctors.
Conclusions: I. Only politicians are police.
II. Only police are politicians.
III. No humans are cops.
IV. Some cops are not humans.
(b) + (c) = A + A = All police are politicians. But this can't be interprected as either I or II (Note : If Only politicians are police then All police are politicians is true. But not vice versa.) Again (a) + (b) = E + A = O* = Some humans are not cops. Hence III and IV do not follow.
Statements: a. All jugs are slates.
b. All tumblers are slates.
c. No slates are pots.
d. All pots are cauldrons.
Conclusions: I. Some cauldrons are jugs.
II. Some cauldrons are not tumblers.
III. Some cauldrons are tumblers.
IV. No cauldrons are tumblers.
statement (b) + statement (C) gives conclusion No tumblers are posts [Because, A + E = E]. Now, No tumblers are posts + statement (d) gives conclusion II. [Because, E + A = O*]. Again conclusion III and IV make I-E type pair. Hence, either III or IV also follows.
Statements: a. Some bags are charts.
b. Some charts are not docks.
c. No docks are trees.
d. Some trees are bridges.
Conclusions: I. Some docks are not bridges.
II. No charts are trees.
III. No trees are charts.
IV. Some bags are not docks.
(c) + (d) = E + I = O* = Some bridges are not docks. Hence I does not follow. (b) + (C) = O + E = No conclusion. Hence II and III do not follow. (a) + (b) = I + O = No conclusion. Hence IV does not follow.
Odd-positioned letters of English alphabet are arranged in alphabetical order than even-positioned letters are arranged in alphabetical order.
In the word CUSTOMER, C, U, S, O, M and E are odd-positioned letters of English alphabet. Therefore C, E, M, O, S and U become the first six letters of the code of CUSTOMER. The position of R comes before. T. Hence, the last two letters of the code are R and T. Similarly AVOUCH is coded as ACOUHY.
If only the consonants in the word SALE are changed insuch a way that each of them becomes the next letter in the English alphabet and the remaining letters are kept unchanged, then how many meaningful words can be formed with the new set of letters using each letter once and only once in a word ?
