Solution

The correct option is A $\frac{37}{24}$
$(\frac{7}{4} \times \frac{3}{14}) + (\frac{13}{2} \times \frac{7}{39})$

$= (\frac{7}{4} \times \frac{3}{2 \times 7}) + (\frac{13}{2} \times \frac{7}{3 \times 13})$

$= (\frac{1}{4} \times \frac{3}{2}) + (\frac{1}{2} \times \frac{7}{3})$

$= \frac{3}{8} + \frac{7}{6}$

$= \frac{3 \times 3}{8 \times 3} + \frac{7 \times 4}{6 \times 4}$

$= \frac{9}{24} + \frac{28}{24}$

$= \frac{9 + 28}{24}$

$= \frac{37}{24}$
