Answer 1

Is it correct? If it is correct then reply .

Answer 2

Answer:

Rs 325

Step-by-step explanation:

Let the cost price of article ( CP ) = 100 X

Given that gain = 20 %

then the selling price = CP + Gain = 100 X + 20 % 100 X

=100 X + 20 X = 120 X

Given that selling price = 390 Rs.

then,

120X = 390 Rs

X = 390 / 120 = 3.25 Rs

then the cost price = 100 X = 100 * 3.25

= 325 Rs
