Option 1 : 47/12

Concept Used:

Follow the BODMAS rule to solve this question, as per the order given below.

**Calculations:**

Considering the given equation

\(2_3^1 + \left( {3_5^2 \times \frac{5}{4}} \right) - \frac{8}{3} = ?\)

⇒ 7/3 + (17/5 × 5/4) − 8/3 = ?

⇒ 7/3 + (17/4) − 8/3 = ?

⇒ 17/4 − 1/3

⇒ 47/12

**∴ ? = 47/12**
