Question
Who among the following lives just below of the floor
of Y? 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?
(555 + 385 - 535) ÷ 15 X ? = 36 X 30
?/4 ÷ 9/? = 15% of 800 + `1(2/3)` × `1(1/5)` × 1/2
8 × 9 + ? – 6 × 11 = 12 × 8
(√ 196 x √ 36 x √ 100) = ?% of 200
I. x² + 3x – 154 = 0
II. y² + 5y – 126 = 0
- Determine the value of following expression:
[{(148 + 32) ÷ 9}% x 1350] + 19 - Find the value of:
35% of [150% of (45 + 15) + 150] ÷ 75 × 80 √4761 ÷ 23 + √12769 = ? × 58
What will come in the place of question mark (?) in the given expression?
40% of 150 - ?% of 75 = 15 × 1.6
What will come in the place of question mark (?) in the given expression?
? X 7 + (243)⁽²/⁵⁾ = 380 ÷ 2 + 71
