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
