Answer:
mean = sum of the numbers / total number of numbers
2x + 3x + 4x + 5x + 6x = 20x
total number of numbers = 5
mean = 54 (given)
so ,
54 = 20x / 5
20x = 54 * 5 = 270
x = 270 / 20 = 13.5
2x = 2 * 13.5 = 27
3x = 3 * 13.5 = 46 ( approx )
4x = 4 * 13.5 = 54
5x = 5 * 13.5 = 68 ( approx)
6x = 6 * 13.5 = 81
