Question

every week Laila works 3 times as many hours as joseph. let the number of hours Joseph works in a week be X hours. a) of their total number of working hours in a week is 56 hours, find the number of hours Joseph works in a week​

Answer 1

Let the hours Josheph works be X

Since Laila works 3 times as many hours as Joseph, we can say that the hours Laila works for is 3X ( since the number of hours Joseph works for is X and she works 3 times as many hours as him)

Total hours both work for = 56 hours

So, it will be, No. of hours Joseph works everyday + No of hours Laila works everyday = 56 hours

We already know that Joseph works for X hours and that Laila works for 3X hours

So, X+3X = 56 hours

4X= 56 hours

X= 14 hours

Since Joseph works for X hours and we're only required to find the hours he works for, the answer is 14 hours

So, Joseph works for 14 hours in a week
