  • Question 1
    1 / -0

    If 'A' stands for '+', 'B' stands for ′÷′, 'C stands for ′×′  and 'D' stands for ′−′ , then which of the following will be the value of the expression 4 A 6 B 3 C 5 D 4?

    Solution

    4 A 6 B 3 C 5 D 4 = 4 + 6 ÷ 3 × 5 − 4 = 10

     

  • Question 2
    1 / -0

    If '+' means ′÷′,′ ÷′ means ′−′,′−′ means ′×′ and ′×′ means '+', then 110 + 11 −10 ÷ 22 × 18 = ?

    Solution

    110 + 11 −10 ÷ 22 × 18 = 110 ÷ 11 × 10 − 22 + 18 = 96

     

  • Question 3
    1 / -0

    P means 'add', Q means 'subtract', M means "multiply" and N means "divide, then 1 P 3 2 Q 6   N 1   M 0 P 8=?

    Solution

     

    Given expression = 1 + 32 − 6 ÷ 1 × 0 + 8 = 41

     

  • Question 4
    1 / -0

    It is given that ′ϕ′ denotes "divided by", '@' denotes 'plus', '#' denotes 'minus' and '*' denotes 'multiplied by', then what is the value of the expression given below? 14 # 99 ϕ 33 @ 11 * 5

    Solution

    Given expression = 14 − 99 ÷ 33 + 11 × 5 = 66.

     

  • Question 5
    1 / -0

    If 'a' stands for ′×′, 'b' stands for ′÷′, 'c' stands for ′−′ and 'd' stands for'+', then what will be the value of the expression (10 a 3) b (14 c 4) d (19 d 9) ?

    Solution

    Given expression =(10 × 3) ÷ (14 − 4) + (19 + 9) = 31

     

  • Question 6
    1 / -0

    If '+' is ′×′,′−′ is ′+′, ′×′ is ′÷′ and ′÷′ is ′−′, then simplify the following expression: 93 + 4 ÷ 16 × 2

    Solution

    Given expression = 9 + 3 × 4 −16 ÷ 2 = 13.

     

  • Question 7
    1 / -0

    If 'A' stands for 'addition', 'S' stands for 'subtraction', 'D' stands for 'division', 'M' stands for 'multiplication', 'G' stands for 'greater than', 'E' stands for 'equal to' and 'L' stands for 'less than', which one of the following is correct ?

    Solution

    2 L 2 M 4 A 1 M 4 S 8 ⇒ 2 < 2 × 4 + 1 × 4 − 8 ⇒ 2 < 4.

     

  • Question 8
    1 / -0

    If 'L' means ′÷′, 'P' means '+', 'Q' means ′−′ and 'M' means ′×′, then tick the correct equation.

    Solution

    9 P 9 L 9 Q 9 M 9 = 9 + 9 ÷ 9 − 9 × 9 = −71.

    1 / -0

    If ′⇒′ stands for'+' ′⇑′ stands for ′÷′, ′⇓′ stands for ′×′, ′⇐′ stands for ′−′ and ′⊗′ stands for '=', then which of the following statements is correct?

    Solution

    2 ⇓ 5 ⇐ 6 ⇒ 2 ⊗ 6 = 2 × 5 − 6 + 2 = 6 i.e., 6 = 6 which is true.

     

  • Question 10
    1 / -0

    If ′×′ stands for "addition", '<' for 'subtraction','+' for 'division', '>' for 'multiplication, ′−′ for 'equal to', ′÷′ for 'greater than' and '=' for 'less than', then which of the following is true?

    Solution

    5 > 2 + 2 = 10 < 4 × 8 or 5 × 2 ÷ 2 < 10 − 4 + 8 or 5 × 1 < 10 − 4 + 8 or 5 < 14 which is true.
