Let the cost price of 1 pen be x.
The stationer sold 1 dozen of pens, which is 12 pens.
Total selling price = 12 * Rs25 = Rs300
Total profit = Rs120
Therefore, Cost price of 12 pens = Total selling price - Total profit
Cost price of 12 pens = Rs300 - Rs120
Cost price of 12 pens = Rs180
Cost price of 1 pen = Cost price of 12 pens / 12
Cost price of 1 pen = Rs180 / 12
Cost price of 1 pen = Rs15
Therefore, the cost price of the pens was Rs15 each.

12 pens x Rs. 25 = Rs. 300
2. Calculate the profit earned:
Rs. 120 (given in the question)

Cost price = Selling price - Profit
Cost price = Rs. 300 - Rs. 120
Cost price = Rs. 180
Therefore, the cost price of the pens was Rs. 180.
12 pens x Rs. 25 = Rs. 300
