AS by taking the options we can have
6 and 54
1) The AP of the numbers is 30 which is 24 less than larger number
2) And the GP is 18 which is 12 larger than the smaller numbers.

A bird starts flying from a place O towards B via A. There is no wind resistance from O to A. But there is uniform wind resistance between A and B. To travel from O to B the bird takes 12 minutes, whereas to travel from B to O via A, the bird takes 14 minutes. Had there been wind resistance between O and A also (which equals that between A and B), the bird would have taken only 11 minutes to travel from O to B. O, A and B are collinear.If there was the same wind resistance between O and A as between A and B, what would be the time taken by the bird to travel from B to O?

1) 12.5 min
2) 15.4 min
3) 18.2 min
4) none of these
