If '#' represents '−-', ''@@' represents '(\times)', '(\)′represents′)' represents '+′and′(%)′represents′(÷1)′,thenwhatisthevalueof(20 $ 15)(#)10' and '(\%)' represents '(\div 1)', then what is the value of (20 ~\$~ 15) (\#) 10@$ (45 ~\%~ 15) ?

Options

  1. A5
  2. B20
  3. C14
  4. D24

Correct answer

A. 5

Step-by-step solution

Given Equation: 20 (\)15(#)10) 15 (\#) 10@(45 % 15=)?Decodingthegiveninformation:$(<tableclass="qx−match−listqx−match−table"border="1"cellpadding="6"cellspacing="0"><tr><td>Symbol</td><td>#</td><td>@</td><td>\</td></tr><tr><td>Meaning</td><td>−</td><td>×</td><td>+</td></tr></table>)NowreplacingthesignfromlefttorightusingBODMASRule,weget:$((45 ~\%~ 15=) ? Decoding the given information: \$(<table class="qx-match-list qx-match-table" border="1" cellpadding="6" cellspacing="0"><tr><td>Symbol</td><td>\#</td><td>@</td><td>\</td></tr><tr><td>Meaning</td><td>-</td><td>\times</td><td>+</td></tr></table>) Now replacing the sign from left to right using BODMAS Rule, we get: \$(⇒20+15−10×45÷15‾=?⇒20+15−10×3‾=?⇒20+15‾−30=?⇒35−30‾=5.\begin{aligned}& \Rightarrow 20+15-10 \times \underline{45 \div 15}=? \\ & \Rightarrow 20+15-\underline{10 \times3}=? \\ & \Rightarrow \underline{20+15}-30=? \\ & \Rightarrow \underline{\mathbf{3 5}-30}=\mathbf{5} . \end{aligned}$) Hence, the correct option is "Option 1".
