   X = Rs. 50000
   
   
    



2. Sai gave 65% of the amount he had to Ria. Ria gave 2/5th of what he received from Sai to Suma. After paying Rs. 320 to the taxi driver out of the amount he gets from Ria, Suma is now left with Rs. 1500. How much amount did Sai have?

   => 403x/2500 + 133x/1000 = 29420
   => 1471x/5000 = 29420
   = > x = 29420*(5000/1471)
