A certain sum is divided among A, B, C and D such that the ratio of the shares is A : B : C : D = 4 : 12 : 30 : 45. If the difference between the shares of A and D is ₹5,535, then the total sum (in ₹) is:

12285

              A  :  B  :  C  :  D 

Shares    4  : 12  : 30  : 45

Difference between the shares of A and D = 41r = 5535 

                  r = 135

Total sum = 91r = 91 x 135 = ₹ 12,285
