35 labourers work 5 hours everyday and complete their work in 30 days.
If same work is done by 25 labourers in 10 hours everyday, then how many days will required?

Answer 1

Answer: 21 days

Step-by-step explanation:

If 35 labourers work 5 hrs a day = 30 days

If 1 labourer works 5 hrs per day = 30 x 35 = 1050 days

If 25 labourers work 5 hrs per day = 1050/ 25 = 42 days

If 5 hrs per day = 42 days

( 1hr per day= 42 x 5)

10hrs per day = (42x5) / 10= 21 days
