The sale on Monday is 39.

The sale of Thursday is 42

The average sale of Tuesday, Wednesday, Thursday= 45

So total sale on Tuesday, Wednesday, Thursday= 45*3 = 135

Also, total sale of Tuesday and Wednesday only = 135-45 = 90

Average sale on Monday, Tuesday, Wednesday= 43

So the total sale on Monday, Tuesday, Wednesday= 43*3= 129

Therefore, sale on Monday only = 129-90 = 39.
