Answer 1

Answer:

80 hrs

Step-by-step explanation:

shilpa can stitch a shirt in 5 hrs , in 1 hr shilpa can complete 1/5 work

similarly alka can complete 1/4 work

if both together can do it in 1/4+1/5=9/20 work in 1 hr

so for one shirt they will take 20/9 hrs

for 36 shirts they will take x hrs

by cross multiplication x=20/9×36=80 hrs

so both can do it in 80 hrs
