pura solution h
7 men and 27 women can complete the same work in 48/7 days ( Here woman are not working at all as per given data)
Step-by-step explanation:
Let say 1 man 1 day work = m
& 1 Woman 1 day work = w
3 men and 4 women can complete a work in 16 days
=> 16( 3m + 4w) = 1
4 men and 3 women can complete the same work in 12 days
=> 12(4m + 3w) = 1
16( 3m + 4w) = 12(4m + 3w)
=> 4( 3m + 4w) = 3(4m + 3w)
=> 12m + 16w = 12m + 9w
=> 16w = 9w
which means w = 0
Hence women are not working
or Data is wrong
assuming w = 0
48m = 1
=> m = 1/48
7 men and 27 women complete in d days
=> d ( 7m + 27w) = 1
=> d( 7/48 + 0) = 1
=> d = 48/7
