Answer 2

Answer :

3/5 part completed in 1 hour ( 60 minutes )

Let total work = x

so , work completed = 3/5×x = 3/5x

time taken to complete all work :-

3/5x = 60

3x = 60×5

3x = 300

x = 300/3

x = 100

So , total time taken to complete a work = 100 minutes

Then time taken to complete 1 part of total work = 100/5

20 minutes (as previously total work was divided in five parts so divided by 5)

now work done in 11/4hrs will be .....

11/4hrs = 165 minutes

So work completed in 165 minutes = 165/20

→ 33/4

→ 8 1/4

→ 8.25

At last 8.25 is the total work done in 11/4 hrs

Hope this answer is helpful
