Twenty women can do a work in sixteen days. Sixteen men can complete the same work in fifteen days. What is the ratio between the capacity of a man and a woman?
Answer: Option
Explanation:
(20 x 16) women can complete the work in 1 day.
 1 woman's 1 day's work = |
1 | . |
| 320 |
(16 x 15) men can complete the work in 1 day.
| 1 man's 1 day's work = |
1 |
| 240 |
| So, required ratio |

Its very simple,
WOMEN = 20 * 16 = 240.
MEN = 16 *15 = 320.
MEN/WOMEN =320/240 =4/3 (used 80's table).
RATIO = 4 : 3..
Hope this helps.
Thanks.

Women = 20 * 16 = 240,
Men = 16 * 15 = 320,
Men/women=320/240 = 4/3.
Ratio = 4:3.
Men = 16 * 15 = 320,
Men/women=320/240 = 4/3.
Ratio = 4:3.

M1 * D1 = M2 * D2.
20*16 = 16*15,
4 = 3,
4:3.
20*16 = 16*15,
4 = 3,
4:3.

(20w) 16:(16m) 15.
By Cancellation: We get 4:3.

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

20 women ---> 16 days.
20 women ---> 1/16 work in one day.
1 woman ---> 1/ (16*20) in one day.
In the same way,
16 men---> 15 days.
16 men---> 1/15 work in one day.
1 man---> 1/ (15*16) in one day.
To calculate the ratio,
1/ (15*16) : 1/(16*20).
By cancelling 16 on both sides and cancelling 15 and 20 as 3 and 4.
1/3:1/4.
Cross multiply we get;
4:3.

As per question:
20W = 16 days and 16M = 15 days.
So W = 16/20 and M = 15/16.
So M/W = 15/20 = 3/4.
So ratio is 4:3.
20W = 16 days and 16M = 15 days.
So W = 16/20 and M = 15/16.
So M/W = 15/20 = 3/4.
So ratio is 4:3.

20w can take 16 days.
If 16w-----can take 20 days,
16m can take 15 days(given).
so 20:15.
4:3.
