Step-by-step explanation:
The ratio of three numbers are 2:3:4.
Let the rational between the three numbers be x, hence the three numbers be 2x, 3x and 4x.
If their average is 36, what are the numbers
We know Average = sum of the numbers / no. of numbers
Accordingly, average of three numbers
(2x + 3x + 4x) / 3 = 36
9x / 3 = 36
3x = 36
x = 36/3
x = 12
The rational is 12, hence the two numbers are
First number 2x = 2 × 12 = 24
Second number 3x = 3 × 12 = 36
Third number 4x = 4 × 12 = 48
Therefore, the three numbers are 24, 36, and 48.
