Answer:
48 green pens were sold.
Step-by-step explanation:
From the given ratio, let us assume that the number of packs of black pens sold = 7n, the number of packs of red pens sold = 2n and the number of packs of green pens sold = 4n.
Since each pack of black pens contains 3 pens, therefore number of black pens sold = 3 × 7n. Similarly, number of red pens sold = 5 × 2n and number of green pens sold = 6 × 4n.
Now, from the given condition,
3×7n + 5×2n + 6×4n = 220
=> 21n + 10n + 24n = 220
=> 55n = 220
=> n = 4
So, the number of green pens sold on Monday = 6 × 2 × 4 = 48.
