Question
Who among the following lives on the floor numbered
six? Study the following information carefully to answer the given question: Nine persons i.e. A, Z, B, Y, C, N, M, Q and J live on a separate floor of a nine floored building but not necessarily in the same order. The ground floor is numbered as 1, the first floor is numbered as 2 and so on until the topmost floor is numbered as 9. A does not live on the odd numbered floor and doesn’t live just below of the top floor. There are two persons live between A and N, who lives above of the floor in which A lives. Z lives just above of the floor of Q. B lives just below of the floor of J. There are three persons live between N and M, who lives just above the floor of Y. Both B and Q do not live on ground floor. Q lives below of the floor of Y but not just below. The number of persons between J and M is same as between C and Y.Solution
A does not live on the odd numbered floor and doesn’t live just below of the top floor. We get three possibilities here i.e. Case 1, Case 2 and Case 3. There are two floors gap between A and N, who lives above of the floor in which A lives. There are three persons live between N and M, who lives just above the floor of Y. 
From the given statements, Q lives below of the floor of Y but not just below. Here Case 2 is ruled out. Both B and Q do not live on ground floor. Z lives just above of the floor of Q. B lives just below of the floor of J. Here, one more case is added i.e. Case 1a. 
From the given statements, the number of floors gap between J and M is same as between C and Y. Now Case 1 and Case 1a are eliminated here. So, the final arrangement is such as- 
What will come in the place of question mark (?) in the given expression?
30% of 50% of 1200 = 18/11 × ?
25% of 140 + 2 × 8 = ? + 9 × 5
What will come in place of (?) in the given expression.
12.5 + 7.75 - 3.6 = ?Simplify: 3/5 + 0.4 × 2.5
√729 × 5 + 270 - 3 ÷ ∛27 + 4 × ? = 484
2856 ÷ 34 = ?% of 240
612 + 1250 - 728 = ? × 63
What should come in place of (?) question mark in the given expression.
(576 ÷ 12) + (3³ × 4) = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
242 + 80% of 1620 = ? × 16 – 35% of 800
