  1. A, B and C undertake to complete a piece of work for ₹ 2574. A works for 8 days, B for 9 days and C for 12 days to complete the work. If their daily wages are in the ratio of 3 : 5 : 4, what does C get?

    Given in the question ,

    A can complete work in 1 day = 1
    8

    B can complete work in 1 day = 1
    9

    And C can complete work in 1 day = 1
    12

    Ratio of daily wages of A , B and C = 3 : 5 : 4
    Now A for 8 days, B for 9 days and C for 12 days of wages = 3 x 8 : 5 x 9 : 4 x 12 = 24 : 45 : 48
    wages of A , B and C = 8 : 15 : 16

    Correct Option: D

    Given in the question ,

    A can complete work in 1 day = 1
    8

    B can complete work in 1 day = 1
    9

    And C can complete work in 1 day = 1
    12

    Ratio of daily wages of A , B and C = 3 : 5 : 4
    Now A for 8 days, B for 9 days and C for 12 days of wages = 3 x 8 : 5 x 9 : 4 x 12 = 24 : 45 : 48
    wages of A , B and C = 8 : 15 : 16
    We have total wages = 8k + 15k + 16k = 2574
    ⇒ 39k = 2574 ⇒ k = 2574/39 = 66
    Share of C = 16k = 16 x 66 = ₹ 1056



  1. Wage of 10 women for 5 days is ₹ 1250. The daily wage of a man is twice that of a woman. How many men must work for 8 days to earn ₹ 1600?

    Given that :- Wage of Men : Wage of Women = 2 : 1
    Wage of 10 women for 5 days = ₹ 1250.

    Wage of 1 woman for 1 day = ₹1250 = ₹ 25
    10 x 5

    According to question ,
    Wage of 1 man for 1 day = 2 x Wage of 1 woman for 1 day
    Wage of 1 man for 1 day = ₹ 2 x 25 = ₹ 50
    Wage of 1 man for 8 day = ₹ 2 x 25 = ₹ 50 x 8 = ₹ 400

    Correct Option: D

    Given that :- Wage of Men : Wage of Women = 2 : 1
    Wage of 10 women for 5 days = ₹ 1250.

    Wage of 1 woman for 1 day = ₹1250 = ₹ 25
    10 x 5

    According to question ,
    Wage of 1 man for 1 day = 2 x Wage of 1 woman for 1 day
    Wage of 1 man for 1 day = ₹ 2 x 25 = ₹ 50
    Wage of 1 man for 8 day = ₹ 2 x 25 = ₹ 50 x 8 = ₹ 400
    Number of men = 1600 = 4
    400

    Hence , required number of men will be 4 .


  1. A and B undertake to do a work together for ₹ 600. A alone can do it in 15 days and B in 20 days. But with the assistance of C they finish it in 5 days. How is the money to be divided among them?

    Given :- A's one day work =
    1
    15
    B's one day work =
    1
    20

    C’s one day’s work = 1/5 - (1/15 + 1/20) = 5/60.
    C's one day work =
    1
    12

    Thus the ratio of efficiencies of A, B and C is 1/15 : 1/20 : 1/12 = 4 : 3 : 5

    Correct Option: C

    Given :- A's one day work =
    1
    15
    B's one day work =
    1
    20

    C’s one day’s work = 1/5 - (1/15 + 1/20) = 5/60.
    C's one day work =
    1
    12

    Thus the ratio of efficiencies of A, B and C is 1/15 : 1/20 : 1/12 = 4 : 3 : 5
    A ’s share =
    4
    × 600 = ₹ 200
    12

    B ’s share =
    3
    × 600 = ₹ 150
    12

    And C ’s share =
    5
    × 600 = ₹ 250
    12





  1. A person was appointed for a 50 days job on a condition that he will be paid ₹ 12 for every working day but he will be fined ₹ 6 for every day he remains absent. After the completion of the work, he got ₹ 420. For how many days. he did not work?

    Let the person did not work for x days.
    It means that he worked for (50 - x) days.
    ∴ Find for being absent = ₹ 6x
    Wages for working days = 12 (50 - x)
    According to the question,
    Received wages = 12(50 - x) - 6x = 420

    Correct Option: C

    Let the person did not work for x days.
    It means that he worked for (50 - x) days.
    ∴ Find for being absent = ₹ 6x
    Wages for working days = 12 (50 - x)
    According to the question,
    Received wages = 12(50 - x) - 6x = 420
    ⇒ 600 - 12x - 6x = 420
    ⇒ 18x = 600 - 420 = 180
    ∴ x = 180/18 = 10 days
