Explanation

There is gap of only one floor between A1 and the one who earns 50 lives. The one who eans 80 works on an even-numbered floor and just above the floor on which the one who earns 150. A8 does not work on third floor. Al works on an odd-numbered floor and A5 works on the floor which is just above the floor on which A1 works. A2 works on the fourth floor. Two persons work between the one who earns 290 and A1. A6 works just below the one who earns 150. There is a gap of two floors between the floor on which A8 and A5 works. A8 works on floor which is below the floor of A5. A4 does not works on the 1st floor. Only one person works between the one who earns 140 and A4. Therefore, A4 works on `3^("rd")` floor.

The one who earns 210 does not work on an odd numbered floor. A7 does not earn 70. There is a gap of two floors between the one who earns 500 and the one who earns 210. Therefore, the one who earns 210 lives on `6^("th")` floor and A3 on `2^("nd")` floor.
