  1. Question 1 of 28
    1. Question

    If ‘+’ means ‘×’, ‘–’ means ‘÷’, ‘÷’ means ‘+’ and ‘×’ means ‘–’; then what will be the value of the following expression?

    540 – 36 + 12 ÷ 75 × 55

    Hint

    Using the proper signs in the given expression,
    we get, 540 ÷ 36 × 12 + 75 – 55
    = 15 × 12 + 75 – 55
    = 180 + 75 – 55 = 200

  2. Question 2 of 28
    2. Question

    If ‘*’ means ‘×’, ‘$’ means ‘+’, ‘#’ means ‘÷’ and ‘©’ means ‘–’; then what will be the value of the following expression?

    Hint

    5 – 7 × 9 + 3 ÷ 2
    × means +, + means ÷, ÷ means –, – means ×.
    = 5 × 7 + 9 ÷ 3 – 2
    = 5 × 7 + 3 – 2
    = 35 + 3 – 2 = 36

  25. Question 25 of 28
    25. Question

    If ‘20–10’ means 200, ‘8÷4’ means 12, ‘6×2’ means 4 and ‘12+3’ means 4; then what will be the value of the following expression?

    100 – 10 × 1000 ÷ 1000 + 100 × 10

    Hint

    Since, 20×10=200, therefore, – means ×.
    8+4=12, therefore, ÷ means +.
    6–2=4, therefore, × means –.
    and 12÷3=4, therefore, + means ÷.

    Now, given expression
    100 – 10 × 1000 ÷ 1000 + 100 × 10

    Using the correct symbols, we have:
    = 100 × 10 – 1000 + 1000 ÷ 100 – 10
