Questions
1 If '+' means 'minus', '-' means 'added to', '×' means 'divided by' and '÷' means 'multiplied by', then which of the following will be the value of the following expression ?

8 × 2 - 4 + 6 ÷ 2 = ?

A 2
B 4
C 6
D 12

Answer: Option [B]

Rearranging the equation part by part we get,

8 ÷ 2 [Because '×' means 'divided by']

8 ÷ 2 + 4 [Because '-' means 'added to']

8 ÷ 2 + 4 - 6 [Because '+' means '-']

8 ÷ 2 + 4 - 6 × 2

= 4

2 If '+' means '÷', '÷' means '×', '×' means '+' and '-' means '+', then which of the following will be the value of the following expression ?

16 × 4 + 5 - 4 ÷ 4 = ?

A 26
B 28
C 30
D 32

Answer: Option [D]

Rearranging the equation part by part we get,

16 + 4 [Because '×' means '+']

16 + 4 ÷ 5 [Because '+' means '÷']

16 + 4 ÷ 5 + 4 [Because '-' means '+']

16 + 4 ÷ 5 + 4 × 4 [Because '÷' means '×']

= 32

3 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: 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

4 If '÷' means '+', '-' means '×', '+' means '-' and '×' means '÷', then

9 - 9 × 3 ÷ 12 + 8 = ?

A 40
B 31
C 35
D 60

Answer: Option [B]

Rearranging the equation part by part we get,

9 × 9 [Because '-' means '×']

9 × 9 ÷ 3 [Because '×' means '÷']

9 × 9 ÷ 3 + 12 [Because '÷' means '+']

9 × 9 ÷ 3 + 12 - 8 = ? [Because '+' means '-']

= 31

5 If 'P' denotes 'multiplied by', 'R' denotes 'added to', 'S' denotes 'subtracted from' and 'T' denotes divided by, then

16 P 4 T 8 R 12 S 5

A 80
B 54
C 15
D 8

Answer: Option [C]

Rearranging the equation part by part we get,

16 × 4 [Because 'P' means '×']

16 × 4 ÷ 8 [Because 'T' means '÷']

16 × 4 ÷ 8 + 12 [Because 'R' means 'added to']

16 × 4 ÷ 8 + 12 - 5 = ?[Because 'S' means 'subtracted from']

= 15
