Answer / ajay
25 horses can be grouped into 5 . like a,b,c,d,e. each group contains 5 horses. so there are 5 tracks and 5 groups so each race for every group. rank 1 horse from every group will be eligible for further and last round. the final round is for 5 horses. they are top 5.
so the minimum possible races will be 6 only.

Scientist decided to do a study on the population growth of rabbits. Inside a controlled environment, 1000 rabbits were placed. Six months later, there were 1000Z rabbits. At the beginning of the 3rd year, there were roughly 2828Z rabbits, which was 4 times what the scientists placed in there at the beginning of the 1st year. If Z is a positive variable, how many rabbits would be there at the beginning of the 11th year?
