Answer 1

Answer:

1 horse and 1 cow will be Rs 1100 and Rs 450

Step-by-step explanation:

A man purchased 5 horses and 10 cows for rs 10000 he sells the horse at 15% profit and the cows at 10% loss .Thus he gets rs 375as profit find the cost of 1 horse and 1 cow separately

 Let the cost of one horse be equal to k

 Now selling price = k (100 + 15)/100 = 115/100

selling price of each cow will be   (100 – 10) /100 = 90/100

Now selling price will be  

 5 k (115/100) + (10,000 – 5 k) (90 /100) = 10375

 125 k = 1,37,500

  k = 1,37,500 / 125

 k = Rs 1100

Now cost of one horse = Rs 1100  

cost of one cow will be

  10000 – 5 x 1100 / 10

   = Rs 450
