Correct Answer: 78

Explanation:

Given exp = $[\frac{13}{4} � \{\frac{5}{4} - \frac{1}{2} (\frac{5}{2} - \frac{3 - 2}{12})\}]$ = $[\frac{13}{4} � \{\frac{5}{4} - \frac{1}{2} (\frac{5}{2} - \frac{1}{12})\}]$

= $[\frac{13}{4} � \{\frac{5}{4} - \frac{1}{2} (\frac{30 - 1}{12})\}]$ = $[\frac{13}{4} � \{\frac{5}{4} - \frac{29}{24}\}]$

= $[\frac{13}{4} � \frac{30 - 29}{24}]$ =78
