    ∵ 360° ≡ $ 36000

    ∴ 1° ≡
    36000
    = $ 100
    360

    ∴ 60° ≡ 60 × 100 = $ 6000
    ∴ Annual savings = $ (6000 × 12)
    = $ 72000

    Correct Option: B

    ∵ 360° ≡ $ 36000

    ∴ 1° ≡
    36000
    = $ 100
    360

    ∴ 60° ≡ 60 × 100 = $ 6000
    ∴ Annual savings = $ (6000 × 12)
    = $ 72000

    Total funds = Rs. (11486 + 5252 + 4910 + 6000 + 29952) billion
    = $ 57600 billion
    $ 57600 ≡ 360°

    ∴ 29952 ≡
    360
    × 29952
    57600

    = 187.2°

    Correct Option: C

    Total funds = Rs. (11486 + 5252 + 4910 + 6000 + 29952) billion
    = $ 57600 billion
    $ 57600 ≡ 360°

    ∴ 29952 ≡
    360
    × 29952
    57600

    = 187.2°
