Let x = the smallest (odd) integer. The next consecutive odd integer is x + 2, and the two consecutive odd integers after that are x + 4 and x + 6. We can create the equation:

(x + x + 2 + x + 4 + x + 6)/4 = 24

4x + 12 = 96

4x = 84

x = 21, so the largest integer is 27.

Let the ratio be ‘x’.

So, Number became 4x,5x,6x.

Their average is 25.

i.e. 

The numbers became,

The largest number is 30.
