Question

If + means multiplied by, - means divided by, * means plus and / means minus then: (18 + 10 × 20) - 8 ÷ 6 = ?

• A. 92
• B. 35
• C. 26
• D. 19

Hint:

Always replace each symbol with its actual meaning first, then use BODMAS for step-wise calculation.

Answer 1

The Correct Option is D

We are told the operators mean the following:

'+' means multiply ($\times$)
'-' means divide ($\div$)
'*' means add ($+$)
'/' means subtract ($-$)

Original expression: \[ (18 + 10 \times 20) - 8 \div 6 \] Replace each operator as per given meaning: \[ (18 \times 10 + 20) \div 8 - 6 \] Now apply BODMAS (brackets first): \begin{align*} 18 \times 10 &= 180
180 + 20 &= 200
200 \div 8 &= 25
25 - 6 &= \boxed{19} \end{align*}
