Best Answer Explained in Below-:

Let the consecutive integers be n, (n + 1), (n + 2), (n + 3) and (n + 4) respectively. So, n + (n + 1) + (n + 2) + (n + 3) + (n + 4) = 12 x 5 or, 5n + 10 = 60 or, 5n = 60 - 10 or, n = 50 / 5 = 10. So, the least number is 10 and the greatest number is (10 + 4 = 14). Their sum = 10 + 14 = 24.
