Question

A milkman sold two of his buffaloes for 20000 each on one he made a gain 5% and on the other a loss of 10%. Find overall gain or loss .(Hint:Find CP of each)​

Answer 1

Answer:

Let the cost price of one buffalo is Rs. x and that of the other buffalo be Rs. y

S.P. of 1st buffalo = Rs. 20000

i.e. x + 5% of x = 20000

i.e. x = 19047.61

Therefore, cost price of 1st buffalo is Rs. 19047.61

S.P. of 2nd buffalo = Rs. 20000

i.e. y - 10% of x = 20000

i.e. y = 22222.22

Therefore, cost price of 2nd buffalo is Rs. 22222.22

Cost price of both the buffalos = 19047.61+22222.22 = Rs. 41269.83

Selling price of both the buffalos = Rs. 40000

Overall loss = Rs. 1269.83
