Question
If all the persons are arranged in alphabetical order
from bottom to top, then how many persons remain unchanged in their positions? Study the following information carefully and answer the given below. Nine persons- J, K, L, M, N, O, P, Q and R are living in a nine-storey building but not necessarily in the same order. The bottommost floor is numbered as 1 and the floor immediately above it is numbered as 2 and so on. M lives on an even numbered floor but above fifth floor. Only three persons live between M and L. J lives two floors above L. P lives immediately above J. Only one person lives between P and K, who lives above J. As many floors below K as above O. R lives above Q but below N, who doesn’t live on the topmost floor.Solution
We have, M lives on an even numbered floor but above fifth floor. Only three persons live between M and L. From the above condition, there are two possibilities 
Again we have, J lives two floors above L. P lives immediately above J. Only one person lives between P and K, who lives above J. 
Again we have, As many floors below K as above O. R lives above Q but below N, who doesn’t live on the topmost floor. So Case1 gets eliminated, hence the final arrangement becomes 
(22 + √3364)/(? + 4) = 10
What value should come in place of (?) question mark.
[36% of 250 + (3/5 of 320) − 18] ÷ 6 = ?
What value should come in the place of (?) in the following questions?
(√1225 × 14) ÷ 5 + 95 × 55 = ?
(25.111 % of 200) × 26 ÷ 12.99 – 18.88 × 15.82 + 150.33% of 3√ 4917 = ? – 200
...2*1/3 + 22*1/3 + 222*1/3 + 2222*1/2 + 22222*1/2 = ?
What will come in the place of question mark (?) in the given expression?
? X √36 - 184 = 62 X 4
- What will come in place of (?) in the given expression.
48 ÷ 4 × 5 + 36 – 18 = ? 26 X √25 + 15 - 80% of 120 = ?2Â
