A man purchased a cow for Rs. 3000 and sold it the same day for Rs. 3600, allowing the buyer a credit of 2 years. If the rate of interest be 10% per annum, then the man has a gain of:

A. 0% B. 5%
C. 7.5% D. 10%

• C.P. = Rs. 3000.
  S.P. = Rs.(3600 x 100)/(100 + (10 x 2))= Rs. 3000.
  Gain = 0%.

• The value of Rs.3000 after 2 years(assuming the same is compounded)
  A=P(1+R/100)^n=,
  Substituting the values, we get A=Rs.3,630
  Therefore, the net loss=Rs.30(3630-3600)

• 600 = pnr/100
  therefore 600 = 3000*2*r/100
  therefore r = 10%
