Question

A person buys a horse and a cart for Rs. 12000. He sells the horse at 12% profit and the
cart at 4% loss. If he makes a profit of 6% on the whole, find the cost of the horse.​

Answer 1

Answer:

cost of horse is 7500

Step-by-step explanation:

let x be CP of horse

(12000-x) cP of cart

horse sells at profit of 12%

SP=112%x

cart sold at loss of 4%

SP=(100-4)%

   =96%(12000-x)

over all profit is 6% of 12000=720

total amount  100%+6%=12720

SP of both horse and cart equal total amount

112%x+96%(12000-x)=12720

112x+1152000-96x=1272000

16x=120000

x=7500
