If 'R' denotes '-', 'Q' denotes '×', 'W' denotes '÷' and 'A' denotes '+', then

Answer & Explanation

Option: [D]

Rearranging the equation part by part we get,

18 × 3 [Because 'Q' means '×']

18 × 3 + 10 [Because 'A' means '+']

18 × 3 + 10 - 4 [Because 'R' means '-']

18 × 3 + 10 - 4 ÷ 5 [Because 'W' means '÷']

= 12
