Option 4) 20

Total men hours of work = 20 x 10 x 8 = 1600
So 1 man, 1 hr work = 1/1600
As woman is 33.33% more efficient, so 1 woman, 1 hr work=(133.33/100) x (1/1600)=1.3333/1600
So 10 days work of 1 woman working 6 hrs =10 x 6 x (1.3333/1600) = 1/20
Hence 20 women are required.

Alternate Method:
(M x D1 x H1) = (W x D2 x H2)
Here W=1.3333M = (4/3)M
=> (20 x 10 x 8) = (W x 10 x 6) x (4/3)
=> W = 20
