Answer:
32.4
Step-by-step explanation:
1st way
let the numbers be 2x,3x,5x,8x and 9x
ATP,
2x+3x+5x+8x+9x = 162
27x = 162
x = 162/27 = 6
then,
a = 2x = 12
b = 3x = 18
c = 5x = 30
d = 8x = 48
e = 9x = 54
average of all these numbers = (12+18+30+48+54)/5 = 32.4
2nd way
without finding x we can do it because
average = sum of all the numbers/total number of numbers
average = 162/5 = 32.4
this way is very easy
