**Soln.**

**Ans: a**

Observe that all fractional numbers are having one digit to the right of the dot. So we can cancel all the dots and get a plain expression: ${(-82) × 72 - 32 × (-34)}/25$. We can now simpilfy the minus signs to get ${(32 × 34) - (82 × 72)}/25$ which equals ${-4816/25}$, which is same as: $-192{16/25}$
