$5 \frac{17}{18} \times 2 \frac{10}{11} \div \frac{8}{3} = ?$

[UK GBO, 2008]

$34 \frac{3}{11}$

$12 \frac{49}{66}$

$71 \frac{1}{3}$

$55 \frac{7}{8}$

None of these

Explanation

We follow the rule of BODMAS to solve the expression

$= \frac{107}{8} \times \frac{32}{11} \div \frac{8}{33} = \frac{107}{8} \times \frac{32}{11} \times \frac{33}{8} = \frac{107}{18} \times 12 = \frac{214}{3} = 71 \frac{1}{3}$

Hence, Option C is correct.
