Given that there are 12 lins for every 4 jooghs, it means there are 3 lins for every 1 joogh.
If Farmer Coraz has 50 lirns on his farm, we can find the number of jooghs by dividing the number of lirns by the ratio of lins to jooghs:
Number of jooghs = 50 lirns/ 3 joogh
Number of jooghs = 50/3
Since we can't have a fraction of a joogh, we'll round down to the nearest whole number.
So, Farmer Coraz has approximately 16 jooghs on his farm.
