Answer 1

Answer:

$the \: cow \: was \: bought \: for \: rs.7200$

Step-by-step explanation:

$sp = 7290$

$profit\% = 10$

If he had a profit of 10 %then :

SP - 10%of CP =x

Sp-10/100*CP=CP

7920-x/10=x

(79200-x)/10=x

79200-x=10x

79200=11x

x=79200/11

x=7200

answer : the cow was brought for rs .7200
