    Given:

    Ram alone can complete a work in 20 days

    Shyam alone can complete a work in 15 days

    Formula:

    Total work = Efficiency × Time

    Calculation:

    Total work = 60 units (LCM of 20 and 15)

    Efficiency of Ram = 3 units/day

    Efficiency of Shyam = 4 units/day

    Work done by Ram in 3 days = 3 × 3 = 9 units

    Remaining work = 60 – 9 = 51 units

    ∴ Time taken by Ram and Shyam remaining work = 51/(3 + 4) = 51/7 days

    Ram takes 20 days to do one bit of work. So, he is working at a rate of 1/20 of work per day.

    Shyam takes 30 days to do one bit of work. So, he is working at a rate of 1/30 of work per day.

    Together, both are completing 1/20 and 1/30 of the work. 1/20 + 1/30= 5/60 = 1/12 (cross multiplication method).

    Therefore, their rate together is 1/12 of the work per day. So, it will take them 12 days in total.

    Ram takes 20 days to complete a piece of work.

    Shyam takes 30 days to complete a piece of work.

    Ram completes (1/20) of a piece of work in 1 day.

    Shyam completes (1/30) of a piece of work in 1 day.

    Together R and S complete (1/20) + (1/30) = (1/12) of a piece of work in 1 day.

    (1/12) of a piece of work - 1 day

    (12/12) of a piece of work - (12/12)/(1/12) = 12 days.

    R and S take 12 days to complete a piece of work when they work together.

    Ram takes 20 days Shyam takes 30 dyas

    Ram is 50% quicker than Shyam and therefore would do 60% of the work.

    20X60%=12

    So it would take 12 days if they worked together.

    given that:

    Solution Verified by Toppr Ram's efficiency = 20 1 ​ =5%

    Shyam's efficiency =

    30 1 ​ =3.33% Total work =100%

    If both work together then efficiency =5+3.33=8.33%

    Let Ram and Shyam finishes a work in x days then

    x= 8.33 100 ​ x=12

    If both of them work at it together , in 12 days they will be able to finish the work.
