together in how many days will they will able to finish
the work?​

Answer 1

✔ Rationale : -

★ Given :

» Ram can do a work in 20 days.

» Shyam can do a work in 30 days.

★ To find :

» If both Ram and Shyam work together , How many days will it take = ?

Let the number of days did Ram take be x .

Let the numbef of days did Shyam work be y .

So ,

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

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

Now if both do at the same time , then

$\dfrac{1}{x} + \dfrac{1}{y} = \dfrac{1}{20} + \dfrac{1}{30}$

$\bf \: lcm = 60$

$= \dfrac{3 + 2}{60}$

$= \dfrac{5}{60} = \dfrac{1}{12}$

» Hence If both Ram and Shyam work together, They will take 12 days to complete the work.
