A, B and C started a business by investing ₹13,750, ₹16,250 and ₹18,750, respectively. If B's share in the profit earned by them is ₹5,200, what is the total profit (in ₹) earned by them together?

15,600

                            A      :     B      :    C     

Money invested    3750  :  16250  :   18750

                              11  :     13    :     15 

Let the profit be 11x, 13x, 15x                 

Profit earned by B =   ₹5200 = 13x      

                                      x  = 400

Total profit = 39x = 39 x 400 =  ₹15,600
