Explanation:

Let the total goods be 300
One third, means 100 goods are sold at 15? profit
25? means 75 goods are sold at 20? profit
The rest, means 125 goods are 20? loss
Let the price of each good be Re. 1
So, now calculating the profit and loss amounts:
For 100 goods, profit is 15? = Rs. 115
For 75 goods, profit is 20? = Rs. 90
For 125 goods, loss is 20? = Rs. 100
So, total amount of the selling price= Rs. 305
Total cost price = Rs.300
So, the profit = Selling price- cost price = Rs. 305-300 = Rs.5
Now equating it to the real values:
Rs. 5 is the profit when total amount of goods is Rs 300.
Rs. 138.50 is the profit when total amount of goods is= (300/5)*138.5 = Rs. 8310
The value of the goods is Rs. 8310.
