A ranch has both horses and ponies. Exactly 3/10 of the ponies have horseshoes, and exactly 5/8 of the ponies with horseshoes are from Iceland. If there are 3 more horses than ponies, what is the minimum possible combined number of horses and ponies on the ranch?  Choose one
A) 130
B) 141
C) 152
D) 163
E) 174
3/10*P are ponies with horseshoes, so P is a multiple of 10.   5/8*3/10*P = 3/16*P are Icelandic ponies with horseshoes, so P is a multiple of 16.   The minimum value of P is 80. Then H = P+3 = 83.   The minimum number of horses and ponies is 163.   The answer is 163.
