Steps: 2 Marks
Result: 1 Mark
(i) Profit earned by selling one pen = Re 1
Profit earned by selling 45 pens = Rs 45, which we denote by + Rs 45
Total loss= Rs 5, which we denote by (– Rs 5)
Profit earned + Loss incurred = Total loss
Therefore, Loss incurred = Total Loss – Profit earned
= Rs (– 5 – 45) = Rs (–50) = (– 5000 paise)
Loss incurred by selling one pencil = 40paise
which we write as (– 40paise)
So, number of pencils sold
$=(–5000)÷(–40)=125pencils$.
(ii) In the next month, there is neither profit nor loss.
So, Profit earned + Loss incurred = 0
i.e., Profit earned = – Loss incurred.
Now, profit earned by selling 70 pens = Rs 70
Hence, the loss incurred by selling pencils = Rs 70 which we indicate by (– Rs 70) or (– 7,000 paise).
Total number of pencils sold
$=(–7000)÷(–40)=175pencils$.
