Step-by-step explanation:
Ram complete a work = 15 days
Ram complete a work in 1 day = 1/15
Mohan complete a work = 28 days
Mohan complete a work in 1 day = 1/28
Together they complete a work in 1 day =
1/15 + 1/28
= 28/420 + 15/420
= 43/420
Together, they complete a work = 420/43 days
= 9.767 days
= (Approx. 10 days)
