It should be option A.
Men:women = 240:320.
=3:4.
The question is asking the ratio for men and women, but not for women and men.
Men:women = 240:320.
=3:4.

Formula: M1 H1 D1 = M2 H2 D2.
M (men, women, children).
So 20women * 16 days = 16 men * 15days,
20*16=16*15,
320 = 240 ( we get ),
4 = 3 ( after simplified).
So, 4:3.
M (men, women, children).
So 20women * 16 days = 16 men * 15days,

Here is a simple solution.
20 women do it in 16 days,
16 men do the same in 15 days,
So as the work is the same 20X16 : 16X15,
or that comes to 20:15 as the 16 is common in both the sides.
20:15 ratio is 4:3. done.

3:4 is the correct use formula M1D1/W1 = M2D2/W2.

We can easily find out the answer for this question by reverse thinking.
Take an option A.
Divide 16 by 3 it can't. We can't Divide it exactly. So it is not an answer.
Take option B.
Divide 16 by 4 and 15 by 3 hence it is the answer.

=> 20women, 15men,
=> 20:15,
=> 20/15=4/3,
=> 4:3.
=> 20:15,
=> 20/15=4/3,
=> 4:3.
