Answer & Solution
Correct Answer:
Option
C
Given, $$\frac{4}{3}$$ of 25% $$\frac{18}{19}$$ of 57 = ?
$$\eqalign{ & ? = \left[ {\left( {\frac{{25}}{{100}} \times \frac{4}{3}} \right) \times \left( {\frac{{18}}{{19}} \times 57} \right)} \right] \cr & ? = \frac{1}{4} \times \frac{4}{3} \times \frac{{18}}{{19}} \times 57 \cr & ? = 18 \cr} $$
$$\eqalign{ & ? = \left[ {\left( {\frac{{25}}{{100}} \times \frac{4}{3}} \right) \times \left( {\frac{{18}}{{19}} \times 57} \right)} \right] \cr & ? = \frac{1}{4} \times \frac{4}{3} \times \frac{{18}}{{19}} \times 57 \cr & ? = 18 \cr} $$
