Answer:
2 whole 2/5 hours
Step-by-step explanation:
Manav does a piece of work in 6 hours.
=> Work done by Manav in 1 hour = 1/6
Rustom does a piece of work in 4 hours.
=> Work done by Rustom in 1 hour = 1/4
Work done by both in 1 hour = 1/6 + 1/4 = (2+3) / 12 = 5/12
Hence, the work will be done by both in 12/5 (2⅖) hours.
