Simplify the following:
​$$1\frac{4}{9} \times 5\frac{2}{9} \times 324 + 9\frac{3}{4}$$​​

Correct option is D

Given:
​$$1\frac{4}{9} \times 5\frac{2}{9} \times 324 + 9\frac{3}{4}$$ 
Solution:
​$$1\frac{4}{9} \times 5\frac{2}{9} \times 324 + 9\frac{3}{4}\\\ \\ = \frac{13}{9} \times \frac{47}{9} \times 324 + \frac{39}{4} \\\ \\= \frac{611}{81} \times 324 + \frac{39}{4} \\= 2444 + \frac{39}{4} \\= \frac{9776 + 39}{4} = \frac{9815}{4} = 2453.75$$​​
