A) 3:1
B) 4:3
C) 2:3
D) 2:1
E) 2:4
Work done by 30 women in 1 day = 1/16   Work done by 1 woman in 1 day = 1/(16×30)   Work done by 16 men in 1 day = 1/10   Work done by 1 man in 1 day = 1/(10×16)   Ratio of the capacity of a man and woman =1/(10×16) : 1/(16×30) = 1/10 : 1/30   = 1/1 :1/3 = 3:1   Option 3:1
