Thanking the above posters for their help. A reason for asking about the analysis

is testing whether it is possible to think it out in the alloted time unless there is prior familiarity with the position. So many puzzles are obvious such as mate or winning piece improving position. But a diferent type of puzzle started to show up in which I could not understnd what the problem is.

So I just go down and look for the corresponding analysis statement .
