Solution

The correct option is B
$2323 \frac{1}{3}$

The given expression is

$35 \times 64 + 6 \frac{2}{3} \times 12 \times \frac{1}{2}$

$= (30 + 5) (60 + 4) + (6 + \frac{2}{3}) (12 + \frac{1}{2})$

$= (30 \times 60 + 30 \times 4 + 5 \times 60 + 5 \times 4) + (6 \times 12 + 6 \times \frac{1}{2} + \frac{2}{3} \times 12 + \frac{2}{3} \times \frac{1}{2})$

$= 1800 + 120 + 300 + 20 + 72 + 3 + 8 + \frac{1}{3}$

$= 2323 \frac{1}{3}$
