Question 190

# If all the given persons are made to live in an alphabetical order form bottom to top, the positions of how many of them will remain unchanged?

Solution

J lives on floor numbered four and only two people live between J and O, => O lives on 1st floor.

Only one person lives between O and L, => L lives on 3rd floor.

M lives on even numbered floor and immediately above Q, => M lives on 8th floor and Q lives on 7th floor.

Only one person lives between Q and N, => Q lives on 5th floor.

Similarly, K lives on 6th floor. The arrangementÂ :

If all the persons are made to live in alphabetical order from bottom to top i.e., J on 1st floor , K on 2nd floor , L on 3rd floor and so on.

Thus, positions of only 2 persons i.e., L and N will remain unchanged.

=> Ans - (C)
