14:15:16

12:15:19

13:19:21

56 : 80 : 111

Explanation:

Given ratio of number of candidates is 4:5:6

Let the number of candidates for 3 exams be 4k, 5k and 6k respectively.

After increasing, number of candidates become (140% of 4k), (160% of 5k) & (185% of 6k)
That is, (140x4k)/100, (160x5k)/100 and (185x6k)/100
= 56k/10, 80k/10 and 111k/10

Now, the required new ratio is: 56k/100 : 80k/10 : 111k/10
= 56 : 80 : 111
