The value of : 5.8 + (7.4 ÷ 3.7 × 5) – 6 × 2 ÷ 2.5

Correct option is B

Given:

5.8 + (7.4 ÷ 3.7 × 5) – 6 × 2 ÷ 2.5

Solution:

$$\begin{array}{|c|c|} \hline \textbf{Operation preference wise} & \textbf{Symbol} \\\hline \text{Brackets} &[],{}, () \\ \hline \text{Orders, of} & (power), √ (root) , of \\ \hline \text{Division}& ÷ \\ \hline \text{Multiplication} & × \\ \hline \text{Addition} & + \\ \hline \text{Subtraction} & - \\\hline \end{array}$$

​5.8 + (7.4 ÷ 3.7 × 5) – 6 × 2 ÷ 2.5

= 5.8 + (2 × 5) – 6 × 2 ÷ 2.5

= 5.8 + 10 – 6 × 2 ÷ 2.5

= 5.8 + 10 – 6 × 0.8

= 5.8 + 10 – 4.8

= 15.8 – 4.8

= 11

Thus, the correct answer is (b).
