A man purchases a cow for Rs.3000 and sold it on the same day allowing the buyer a credit of 2 years. If the buyer will pay Rs.3600 after 2 year at a rate of simple interest 50/7 % per annum, then the man has a gain of

• value of Rs3000 after 2 years at 50/7 % S.I will be = 3000 + (3000*2*50/7)/100 = 3000 + 428.57
  = 3428.57
  
  therefore C.P of article after 2 years will be Rs 3428.57
  but the buyer pays Rs 3600
  
  therefore gain = 3600-3428.57 = Rs 171.43

• P.W. of Rs. 3600 due 2 years hence at 50/7 % per annum
  Rs (100*3600/ 100+(50*2/7)) = Rs. 3150
  S.P. = Rs. 3150
  Hence gain = 150*100/3000 = 5 %

• Now interest is 50/7=7.1428 %
  
  so interest for 2 years for 3000 rs. is 214.28 so buyer has to give 3214.28 to the seller..
  
  But it gives 3600 so
  profit=3600-3214.28
  
  Gain=profit=385.71

• value of Rs3000 after 2 years at 50/7 % S.I will be = 3000 + (3000*2*50/7)/100 = 3000 + 428.57
  = 3428.4
  so gain -> 3600-3428.4 = 171.6
  
  and the gain percent =5.72%
