If it takes 3 bricklayers 10 days to build a wall how long does it take 2 bricklayers to build the same wall?

Assume X is the number of each bricklayer's workload per day. To build the same wall, the workload of 3 bricklayers in 10 days should equal to 2 bricklayers' in Y days. Thus, 3*10*X=2*Y*X, rearrange it and get Y=15. It takes 2 bricklayers 15 days to build the same wall.
