Find total number of hours needed to embodied a saree:

Number of hours = 8 x 18 = 144 hours

Find the number of hours needed per day if she wants to finish it in 12 days:

Number of hours per day = 144 ÷ 12 = 12 hours

Answer: Kamala needs to work 12 hours a day for 12 days to finish the saree.

Answer 2

no. of working hours= 18 per day
no. of days embroiled a saree = 18
total no. hours taken for embodying a saree = 18*8=144hours
no. of hours she will work in 12 days= 12*8=96 hours
no. of hours she should work more = 144-96 =48 hours
no. of hours she have to work more per day = 48/12=4 hours
