The total cost of two cows is Rs. 230. The owner sells the first cow at a profit of 50%, and the second one at a loss of 20%. If he sells them at the same price, what are the costs of the two cows?


Rs. 80 and 150.


Rs. 180 and 50.


Rs. 30 and 200.


Rs. 40 and 190.

Ans: a

Let the costs of the cows be C and 230 - C. The sale price is given as same. So (100 + 50) × C = (100 - 20) × (230 - C). Simplifying, we get 150 × C = 80 × (230 - C). Solving for C we get, C = Rs. 80. The cost of the other cow is 230 - 80 = Rs. 150.
