Which of the following symbols should be placed in the blank spaces respectively *(in the same order, from left to right) in order to complete the given expression in such a manner that makes the expression ‘F > N’ and ‘U > D’ definitely false?

F__O__U__N__D

  • A.< , < , > , =
  • B.< , = , = , >
  • C.< , =, = , <
  • D.>=, = , = ,>=
  • E.> , > , = ,<

Answer: C

Correct answer: < , =, = , <

The symbols give F < O = U = N < D. From F < O = N comes F < N, so F > N is definitely false; and from U = N < D comes U < D, so U > D is definitely false. Both statements are required to be false, which needs the opposite relation established in each case rather than merely left open.
