Question

A man purchased a cowband a calf for rs 1300. he sold the calf at a profit of 20% and the cow at a profit of 25%. in this way his total profit was 300/13%. find the cost price of cow.

Answer 1

 let price of cow = x, price of calf = y 

(1) x + y = 1300 
(2) x times 1.25 + y times 1.20 = (x+y) times ( 1 + 300/13) 
leads to 1.25*x + 1.20*y=1600 

solving these two equations gets the answer of x = 800 

Answer 2

Answer:

800

Step-by-step explanation

Total Profit= 1300*300/1300= 300

Let x= the cow price and (1300-x)= the calf

x*25/100 + (1300-x)*20/100 = 300

or, x/4 - x/5 = 300 - 260

or, 5x - 4x = 40*20

x = 800 ans
