Solution : The ratio of chocolate to milk in mixture A = 4 : 3 The ratio of chocolate to milk in mixture B = 5 : 2 Let 5 units taken from mixture A and 6 units taken from mixture B. The ratio of chocolate to milk in new mixture = $(5\times \frac{4}{7} + 6\times \frac{5}{7}):(5\times \frac{3}{7} + 6\times \frac{2}{7})$ = 50 : 27 Percentage of chocolate in new mixture = $\frac{\text{chocolate}}{\text{chocolate + milk}} \times 100$ = $\frac{50}{(50 + 27)} \times 100$ = 64.93% = 65% (approx) Hence, the correct answer is 65%.
