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.

Substitute digits for the letters to make the following subtraction problem true. S A N T A - C L A U S ----------------- X M A S Note that the leftmost letter can't be zero in any word. Also, there must be a one-to-one mapping between digits and letters. e.g. if you substitute 3 for the letter M, no other letter can be 3 and all other M in the puzzle must be 3.
