A milkman sold two of his buffaloes for Rs 20,000 each. On one he made a gain of 5% and on the other a loss of 10%. Find his overall gain or loss. (Hint: Find CP of each)


Given: S.P. of each buffalo = Rs.20,000


S.P. of two buffaloes = Rs40000


One buffalo is sold at 5% gain.


Let C.P. be Rs.100, then S.P. = 100 + 5


= Rs.105


When S.P. is Rs.105, then C.P. = Rs.100


When S.P. is Rs.1, then C.P. =


When S.P. is Rs.20,000, then C.P. =


= Rs.19,047.62


Another buffalo is sold at 10% loss.


Let C.P. be Rs.100, then S.P. = 100 – 10


= Rs.90


When S.P. is Rs.90, then C.P. = Rs.100


When S.P. is Rs.1, then C.P. =


When S.P. is Rs.20,000, then C.P. =


= Rs.22,222.22


Total C.P. = Rs.19,047.62 + Rs.22,222.22


= Rs.41,269.84


Since C.P. >S.P.


Therefore here it is loss.


Loss = C.P. – S.P.


= Rs.41,269.84 – Rs. 40,000.00 = Rs.1,269.84
