Question

If dinesh can complete work in 24 hours and pavan completes same work in 6 hours.then how long will they take to complete the work together

Answer 1

Answer:

4*4/5 hrs i. e. 24/5 hrs

Explanation:

dinesh => 24 hrs

pavan => 6 hrs

here, works = 24 ( LCM of both)

as efficiency = work/ time

so dinesh efficiency= 1 & pavan = 4

efficiency of both together= 1+4 = 5

work can be done by both = 24/5 hrs.

i. e. 4*4/5 hrs.

Answer 2

Time taken complete the work together =  4 hour 48 minutes

Explanation:

Given:

Dinesh complete work = 24 hours

Pavan complete work = 6 hours

Find:

Time taken complete the work together.

Computation:

Time taken complete the work together = 1 / [(1/24) + (1/6)]

Time taken complete the work together = 1 / [(1+4)/24]

Time taken complete the work together = 24/5 hour

Time taken complete the work together =  4 hour 48 minutes
