Answer 1

Answer:

Step-by-step explanation:

Amount of time Shahid took for the same work = 12 hrs

Amount of time Rahul took for the same work = 15 hrs

Now we plus 15 with 12 to get the time they need together.

15 + 12 = 27

= That means that if they work together then they will take 27 Hrs / 1 day and 3 Hrs.
