Answer 1

Answer:

16900 by percenyage formulae

Answer 2

here your answer

1000

explanation:

let the cost price of first cow is x

second cow be 13000-x respectively

ATQ

x×120/100=(13000-x)×140/100

both sides 100 cancel

120x=13000*140-140x

120x+140x=13000*140

260x=13000*140

x=13000*140/260

x=50*140=7000

second cow price is

13000-x=13000-7000=6000.

first cow is 7000

and second is 6000.

now difference between the cost price of

both cow's is

7000-6000=1000.
