Mary, Peter, and Lucy were picking chestnuts. Mary picked twice as much chestnuts than Peter. Lucy picked 5 kg more than Peter. Together the three of them picked 29 kg of chestnuts. How many kilograms of chestnuts did Mary, Peter, and Lucy pick respectively?  Pick:
A) 6, 11 and 12
B) 12, 11 and 6
C) 11, 6 and 12
D) 12, 6 and 11
E) 6, 12 and 11
M = 2P   L = P+5   M + P + L = 29   2P + P + (P+5) = 29   P = 6, M = 12, L = 11   Therefore, Mary, Peter, and Lucy picked 12, 6, and 11 kg, respectively.   The answer is 12, 6 and 11.
