Sum of all observations = 8*40 = 320
5 is added to all observations, so total addition is 8*5=40
New sum=360
New average = 360/8 = 45

Your answer
-------------------
Mean of 8 observations = 40
Sum of total observations = (40 × 8) = 320
5 is added to each observation.
Then,
----------
New mean = (320 + 8×5)/8
=> (320 + 40)/8
=> 360/8
=> 45
