k + 2k + 6k = 162. k = 18. mark = 6k = 108

Agree with above approach. here is another way to do it (bit longer though)
P = 2K or K = P/2 and P = M/3 or M = 3P

P + K + M = 162
P + P/2 + 3P = 162

2P + P + 6P = 162*2
9P = 162*2
P = 18*2 = 36

K = 36/2 = 18 AND M = 3*36 = 108

M-K = 90

P=2K=1/3M
P+P/2+3P=162
P=36, M=108,K=18
M-K=90
Ans is D
