Question

if a girl writes for 6 hours a day then she can copy a book in 12 days how many hours per day should write so that we can finish the same work in 8 days

Answer 1

Answer : 9 hours

Brainly solution :

Number of hours the girl writes the book each day = 6 hours.

Number of days taken = 12 days.

Total time required to complete the work = 12 × 6 = 72 hours.

Now, Number of days = 8 days.

Let number of hours she should work on = x hours.

8 × x = 72

x = 72 / 8

x = 9 hours.

Therefore, The girl needs to work 9 hours each day to complete in 8 days.

Answer 2

No.of hours a girl spends on writting=6hrs
No.of days in which she finishes the book=12 days
Therefore total hrs she write=6×12=72
So,the no. of hrs she should write to complete the book in 8 days=72/8
=9
