Let 1Man does 1unit/hr of work
15M in 21 days of 8hrs will do (15*21*8) units
3W = 2M
1W=(2/3)units/hr
21W with 6hrs a day will take (15*21*8)/(21*6*(2/3)) days
=> 30 Days
ANSWER => (a)

work done by 1 men in one hour = 1/(15*21*8)
work done by 2 men in one hour = 2/(15*21*8)
work done by 3 women = work done by 2 men in one hour = 2/(15*21*8)
work done by 21(7*3) women in one hour = 7* (work done by 3 women) = 1/180
work done by 21(7*3) women in six hour = 6/180 = 30 days
