    ∵ 360° 7200 acres

    ∴ 1° ≡
    7200
    		= 20 acres
    360

    ∴ 70° ≡ 70 × 20 = 1400 acres

    Correct Option: D

    ∵ 360° 7200 acres

    ∴ 1° ≡
    7200
    		= 20 acres
    360

    ∴ 70° ≡ 70 × 20 = 1400 acres

  1. What per cent of total land is used for cultivation?








  1. View Hint View Answer Discuss in Forum

    ∵ 360° ≡ 100%

    ∴ I° ≡
    100
    360

    ∴ 90° ≡
    100
    		× 90 = 25%
    360

    Correct Option: B

    ∵ 360° ≡ 100%

    ∴ I° ≡
    100
    360

    ∴ 90° ≡
    100
    		× 90 = 25%
    360

  1. The difference between the measure of central angles of sector for binding charges and advertisement charges is :








  1. View Hint View Answer Discuss in Forum

    Central angle for binding charges

    =
    360
    		× 18 = 64.8°
    100

    Central angle for advertisement charges
    =
    360
    		× 18 = 64.8°
    100

    ∴ Required difference = 0°
    Method 2 :
    Percentage value for both is same.
    Therefore, difference between angles is same.

    Correct Option: D

    Central angle for binding charges

    =
    360
    		× 18 = 64.8°
    100

    Central angle for advertisement charges
    =
    360
    		× 18 = 64.8°
    100

    ∴ Required difference = 0°
    Method 2 :
    Percentage value for both is same.
    Therefore, difference between angles is same.
