A farmer bought a buffalo for ₹44000 and a cow for ₹18000. He sold the buffalo at a loss of 5% but made a profit of 10% on the cow. The net result of the transaction is
(a) loss of ₹200
(b) profit of ₹400
(c) loss of ₹400
(d) profit of ₹200

Solution:

Given, a farmer bought a buffalo for ₹44000 and a cow for ₹18000

He sold the buffalo at a loss of 5%

He made a profit of 10% on the cow

We have to find the net result of the transaction

According to the question,

CP of buffalo = ₹44000

Loss = 5%

We know, Loss % = Loss/CP × 100

5 = loss/44000 × 100

5 = loss/440

Loss = 5 × 440

Loss = ₹2200

Loss = CP - SP

2200 = 44000 - SP

SP = 44000 - 2200

SP of buffalo = ₹41800

CP of cow = ₹18000

Profit = 10%

We know, Profit % = Profit/CP × 100

10 = profit/18000 × 100

10 = profit/180

Profit = 10 × 180

Profit = ₹1800

Profit = SP - CP

1800 = SP - 18000

SP = 180 + 18000

SP of cow = ₹19800

Considering whole transaction,

CP = 44000 + 18000 = ₹62000

SP = 41800 + 19800 = ₹61600

Loss = CP - SP

= 62000 - 61600

= 400

Therefore, net loss of ₹400
