Answer 1

cost of cow and horse = 3,00,000

1)profit of cow = 60,000

2)loss of horse = 30,000

let 2 be x and 1 be 2x

x + 2x = 3,00,000

3x = 3,00,000

x= 3,00,000/3

x = 1,00,000

horse's cost price = 1,00,000

cow's cost price = 2x

= 2,00,000

Answer 2

Given:

The cost price of a cow and a horse is 3 lakhs.

The cow is sold at 20% profit and horse at 10% loss.

Overall gain is Rs.4200.

To Find:

What is the cost price of the cow?

Solution:

Let the price of cow be x

The cost price of a cow and a horse is 3 lakhs.

So, Price of horse = 300000-x

Cow's case :

CP of cow = x

Profit% = 20%

$SP=CP+Profit=x+20\%x=1.2x$

Horse's case:

CP of Horse = 300000-x

Loss% = 10%

SP=CP-Loss

SP=(300000-x)-0.1(300000-x)

Total CP = 300000

Total SP = 1.2x+(300000-x)-0.1(300000-x)

Overall gain = Total SP - Total CP

4200=1.2x+(300000-x)-0.1(300000-x)-300000

x=114000

Hence The cost price of cow is Rs.114000
