HEY Buddy.......!!! here is ur answer

Rohan is two times faster than Mohan.

So, when Mohan completes a work in 18 days then Rohan completes the same work in = 18/2 = 9 days

Now, Rohan completes a work in = 9 days

So,the work that Rohan completes in a day = 1/9

and if Mohan completes a work in = 18days

So, the work that Mohan completes in a day = 1/18

Therefore They do the work together in a day = 1/18 + 1/9 = 3/18

And now completes the work together = 18/3
= 6 days

I hope it will be helpful for you....!!

THANK YOU ✌️✌️
