  • Question 1/10
    1 / -0

    If ‘P’ means ‘divided by’, ‘R’ means ‘multiplied by’, ‘T’ means ‘added to’ and ‘W’ means ‘subtracted from’, then; 60 T 48 P 8 W 6 R 9 = ?

    Solutions

    60 T 48 P 8 W 6 R 9 = ?
    ⇒ 60 + 48 ÷ 8 – 6 × 9 = ?
    ⇒ 60 + 6 – 54 = ?
    ⇒ 12 = ?

  • Question 2/10
    1 / -0

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

    ’40 $ 20 @ 2 # 40 * 20 # 38′

    Solutions

    40$20@2#40 * 20#38
    40 – 20 × 2 + 40 ÷ 20 + 38
    = 40 – 20 × 2 + ⁴⁰⁄₂₀ + 38 = 40 – 40 + 2 + 38

  • Question 3/10
    1 / -0

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

    288 – 32 + 6 × 45 ÷ 9 = ?

    Solutions

    ? = 288 ÷ 32 × 6 – 45 + 9
    or ? = 9 × 6 – 45 + 9
    or ? = 54 – 45 + 9 = 18

  • Question 4/10
    1 / -0

    ‘P’ indicates ‘+’, ‘R’ indicates ‘÷’, ‘T’ indicates ‘–’ and ‘W’ indicates ‘×’; then what will be the value of the following expression?

    40 R 8 W 10 T 12 P 16 = ?

    Solutions

    40 R 8 W 10 T 12 P 16 =?
    or ? = 40 ÷ 8 × 10 -12 + 16
    or ? = 5 × 10 – 12 + 16
    or ? = 66 – 12 = 54

  • Question 5/10
    1 / -0

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

    15 ÷ 5 × 9 + 3 – 6 = ?

    Solutions

    15 ÷ 5 × 9 + 3 – 6 = ?
    or ? = 15 × 5 – 9 ÷ 3 + 6
    or ? = 15 × 5 -3 + 6
    or ? = 81 – 3 = 78

  • Question 6/10
    1 / -0

    If ‘M’ means ‘÷’, ‘R’ means ‘+’, ‘T’ means ‘–’ and ‘K’ means ‘×’; then what will be the value of the following expression?

    20 R 16 K 5 M 10 T 8 = ?

    Solutions

    ? = 20 R 16 K 5 M 10 T 8
    or 20 + 16 × 5 ÷ 10 – 8
    or 20 + 16 × ⁵⁄₁₀ – 8
    or 20 + 8 – 8 = 20

  • Question 7/10
    1 / -0

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

    20 × 12 + 4 – 16 ÷ 5 = ?

    Solutions

    – ⇒ +, × ⇒ –, ÷ ⇒ ×, + ⇒ ÷
    20 × 12 + 4 – 16 ÷ 5 = ?
    or ? = 20 – 12 ÷ 4 + 16 × 5
    or ? = 20 – 3 + 80 = 97

  • Question 8/10
    1 / -0

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

    5 – 7 × 9 + 3 = 2

    Solutions

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