Re: A problem to solve
The solution is pretty simple
They are three consecutive numbers.
Let the first number be X
Second number = X + 1
Third number = X + 2
Sum of three consecutive numbers = 60
X + X + 1 + X + 2 = 60
3 X + 3 = 60
3 X = 57
X = 19
X + 1 = 19 + 1 = 20
X + 2 = 19 + 2 = 21
19 + 20 + 21 = 60
The three consecutive numbers are 19, 20 and 21.
