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
