Loss on buffalo = 10, 000 * 12/100 = 1,200
Gain on Cow = 7, 500 * 20/100 = 1, 500
Gain total = 1, 500 - 1,200 = 300
total gain % = 300 / (10,000+7,500) * 100 = 300/175 %

SP = CP * (100 + gain%) /100 ,
CP = 900 * 100 / 120
Gain = SP - CP

SP = (100 - loss%) * CP / 100
CP = 45 *100/80
new SP = CP ( 100 + profit%) / 100 , profit % = 20%
calculate

CP = 132 * 100 / 120 = ...

kvnmurty: are u a student or not ? which class are u in ? u must learn to understand the way a question is solved and then calculate yourself. i suppose u know to use the calculator and to do them by urself. it is not at all right to ask for others to do that for u

kvnmurty: it is understandable if u dont know how to solve a problem. it is very bad to ask others to calculate.
