    A' s 1 day's work = 1/8
    B' s 1 day's work = 1/10
    ∴ A' s share : B' s share
    = 1/8 : 1/10 = 5/40 : 4/40 = 5 : 4
    Let A' s share = 5k
    and B' s share = 4k.
    According to the question,
    5k + 4k = 900

    Correct Option: B

    A' s 1 day's work = 1/8
    B' s 1 day's work = 1/10
    ∴ A' s share : B' s share
    = 1/8 : 1/10 = 5/40 : 4/40 = 5 : 4
    Let A' s share = 5k
    and B' s share = 4k.
    According to the question,
    5k + 4k = 900
    ⇒ 9k = 900
    ∴ k = 100
    ∴ A' s share = 5k = 5 x 100 = ₹ 500
    and B' s share = 4k = 4 x 100 = ₹ 400.

    A's 1 day's work = 1/3
    B's 1 day's work = 1/2
    A's share : B's share = 1/3 : 1/2 = 2/6 : 3/6
    = 2 : 3

    Correct Option: A

    A's 1 day's work = 1/3
    B's 1 day's work = 1/2
    A's share : B's share = 1/3 : 1/2 = 2/6 : 3/6

    Work done by (P + Q) = 7/22
    Work done by R = 1 - (7/ 22) = (22-7)/22 = 15/22
    ∴ (P + Q)'s share : R's share = (7/22) : (15/22)

    Correct Option: A

    Work done by (P + Q) = 7/22
    Work done by R = 1 - (7/ 22) = (22-7)/22 = 15/22
    ∴ (P + Q)'s share : R's share = (7/22) : (15/22) = 7 : 15
    R's share = (15/22) x 1100 = 15 x 50 = ₹ 750
