the ans must be 27 : 22 .. coz 11 : 12 * 9
9 : 8 * 9
v gt 99 : 108 and 99 : 88 since p is common ans of q :r is 108 : 88 v simplify and get 27 : 22
i made a blunder 11 : 12 * 9 = 99 : 108
9 : 8 * 11 = 99 : 88
therefore , 99 : 108 : 88
q : r = 108 : 88
simpifying i got 27 : 22 ... if it is wrong pls let me knw
yes ur right 
if u have any mre doubts pls ask me it wld enrich my knowledge
