8 and 5
41 & 39 = 1599. (40 x 40 = 1600 but I assume you meant different numbers)
If the product of the two numbers is the sum times 24, then the product of the two numbers is 2400. 40 times 60 is 2400, and 40 plus 60 is 100. The two numbers are 40 and 60.
1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75

41 & 39 = 1599. (40 x 40 = 1600 but I assume you meant different numbers)
The sum of the first 40 whole numbers is 780.
