Answer:

plzz follow me if it helps you

Step-by-step explanation:

Madhavi alone can stitch a shirt in 6 hours

Aditi alone can stitch a shirt in 4 hours

(ii) we need to find out the half of 15

now we need to find out how much time will Aditi

take to stitch 7.5 shirts

•Aditi will take 30 hours to complete 7.5 shirts

now we need to find out how much time will Madhavi take to stitch 7.5 shirts

Madhavi will take 45 hours to complete 7.5 shirts

now we will need to find total time

they will take 75 hours all together to complete 15 shirts

(i) now we need to divide the total time

hence they will take five are all together to complete one shirt

Answer 2

Answer:

Step-by-step explanation:

so first of all lets divide 15 = 7.5 now aditi takes 4 hours to stich one shirt so 4x7.5=30 and 6x7.5=45 45+30=75 together it takes 75 hours to stitch 15 shirts and 75/15=5hrs. for one shirt
