Total profit = $185
 
75 old pen are sold.
 
Total loss = 75 × 1 = 75
 
Since it is loss so we will denote this by - 75.
 
We know that,
 
Total profit = Profit earned by selling note books - Total loss
→ Profit earned by selling note books = 185 + 75 = 260
 
Numbe of note books sold = 260 ÷ 5 = 52
