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

18 Q 3 A 10 R 4 W 5 = ?

[A] 80

[B] 75

[C] 60

[D] 45

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
