| Sunday | 20% of 10,500 | 2100 |
| Monday | 8% of 10,500 | 840 |
| Tuesday | 9% of 10,500 | 945 |
| Wednesday | 22% of 10,500 | 2310 |
| Thursday | 15% of 10,500 | 1575 |
| Friday | 10% of 10,500 | 1050 |
| Saturday | 16% of 10,500 | 1680 |
Ratio of vanilla cake and chocolate cake sold on Friday = 4 ∶ 3
4x + 3x = 1050
⇒ 7x = 1050
⇒ x = 150
Number of vanilla cake sold = 4 × 150
⇒ 600
Number of chocolate cake sold = 3 × 150
⇒ 450
Amount earned on cake sold = 600 × 8 + 450 × 7
⇒ 4800 + 3150
⇒ 7950
∴ The total amount earned by selling all vanilla cakes and chocolate cakes on Friday is Rs.7950
