Question
Statements:Â M ! N, N ^ O, O # N, N @ P
Conclusions:    I. M @ N    II. N ^ M       III. O ! P                 IV. S % N In the following questions, the symbols @, ^, %, # and ! used with the following meaning as illustrated below: ‘T ^ U’ means ‘T is not smaller than U’ ‘T@U’ means ‘T is neither smaller than nor equal to U’ ‘T # U’ means ‘T is neither greater than nor equal to U’ ‘T % U means “T is neither greater than nor smaller than T’ ‘T ! U’ means ‘T is not greater than U’ Now, in each of the following questions assuming the given statements to be true, find which of the four conclusions I, II, III and IV is/are definitely true and give your answer accordingly.Solution
Decoded Statement: M ≤ N, N ≥ O, O < N, N > P Decoded conclusion:  I. M > N                   II. N ≥ M                              III. O ≤ P                              IV. S = N M ≤ N ≥ O < S > P                           M ≤ N. Hence conclusion I is not true. M ≤ N ≥ O < S > P                             M ≤ N. Hence conclusion II is true. M ≤ N ≥ O < S > P                           No relationship can be established between O and P. Hence conclusion III is not true. M ≤ N ≥ O < S > P            No relationship can be established between S and N. Hence conclusion IV is not true.
- Find the simplified form of the following expression:
128 - 85 of 2 + 26 X 4 4387897 – 3286871 – 51926 = ?
(22.5 × 24) ÷ 40 + 51.50 = ? ÷ 5.25
30% of 60% of 1800 + 13 × 14 = (? ÷ 75) × 5
25% of 400 + 3 × 102 = ?2Â
- Identify x such that x% of 540 plus {1080 ÷ x of 9} × 6 gives 162
(64/25)? × (125/512)?-1 = 5/8
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
72 + 122 - 25% of 600 = ?
(168 ÷ 12 + 19 × 64)/(22+1) = ?
