Step-by-step explanation:
Number of days Rohan required to do piece of work = 24 days Number of days
Raghav required to do piece of work = 30 days
∴ We can calculate, work done by Rohan in 1 day = 1/24 Work done by Raghav in 1 day = 1/30 Now, work done by both Rohan and Raghav together in 1 day= 1/24 + 1/30 = 54/720 = 3/40
