Question

The value of {3/5×[3+{3+(11+5+6)}]} is:

A.

126512\frac{ 6}{5}​​

B.

164516\frac{4}{5}

C.

114511\frac{ 4}{5}​​

D.

102510\frac{ 2}{5}​​

Correct option is B

Given: 

{3/5×[3+{3+(11+5+6)}]} 

Concept Used:  

Simplification using BODMAS rule:

Operation preference wiseSymbolBrackets[],,()Orders,of²(power),(root),ofDivision÷Multiplication×Addition+Subtraction\begin{array}{|c|c|} \hline \textbf{Operation preference wise} & \textbf{Symbol} \\ \hline Brackets &[],{}, () \\ \hline Orders, of & ² (power), √ (root) , of \\ \hline Division & ÷ \\ \hline Multiplication & × \\ \hline Addition & + \\ \hline Subtraction & - \\ \hline \end{array}           

Solution:    

35×[3+{3+(11+5+6)}]=35×[3+{3+(22)}] =35×[3+{3+(22)}] =35×[3+{25}] =35×[28] =845=1645\begin{aligned} &​ \frac{ 3}{5}×[3+\{3+(11+5+6)\}] \\ \\ &​ = \frac{ 3}{5}×[3+\{3+(22)\}] \\ \ \\​ &=\frac{ 3}{5}×[3+\{3+(22)\}] \\ \ \\ &= \frac{ 3}{5}×[3+\{25\}] \\ \ \\ &=\frac{ 3}{5}×[28] \\ \ \\ &=\frac{84}{5} = 16\frac{4}{5} \\ \end{aligned}​​
