Edit: fixed the 5th clue from "The owner of the White purse is going to visit Machu Picchu" to "The owner of the White purse is exactly to the right of the woman traveling to visit Machu Picchu".

Answer 1

From 1, 12 & 15

From 18 & 17, women of age 28 & 32 are in adjacent positions in that order. From 9 there are at-least two women on left of youngest woman and one of them is of age 30. Hence youngest woman is in position 3, women of age 28 & 32 are in position 4 & 5 respectively, woman at position 4 is traveling for 5 days and woman at position 2 has white purse and is of age 26. From 4 , 5 & 8 it also follows that woman at position 5 is visiting Sahara, woman at position 1 is visiting Machu Picchu & woman at position 3 is visiting Aztec Pyramid.

From 10 & 2 woman traveling for 20 days is not at extreme left or extreme right. So woman traveling for 20 days is at position 3. From 10 & 13 woman at position 4 is a nurse and is going to Italy. From 14 it follows that hostess is not on extreme right and is therefore at position 2 & the name of the woman at position 1 is Lara. Which leaves position 5 to biologist.

From 19 & 2 it follows that woman with blue purse is in position 4 and woman in position 5 has a yellow purse.

From 16 it follows that the name of the woman at position 3 is Rose and she has a green purse. which leaves the color of the purse of woman at position 1 as red.

From 11 it follows that woman 1 is traveling for 25 days and thus woman 5 is traveling for 10 days. Also from 2 it follows that Ana is at position 4, following which Glenda is in position 5, leaving position 2 to Jessie.

Replacing the travel destinations by the country name and assigning the remaining country name as the destination of woman at position 2 the final result is.

Answer 2

Using the offline version of this Java app, I filled in the following logic grid:

And found that

The first woman is going to China, the second to Peru, the third to Mexico, the fourth to Italy and the fifth to Egypt.

Answer 3

Here is the website-confirmed answer:

CSV:

|            | Woman #1 | Woman #2 | Woman #3 | Woman #4 | Woman #5 |
|------------|----------|----------|----------|----------|----------|
| purse      |   red    |  white   |   green  |   blue   |  yellow  |
| name       |   Lara   |  Jessie  |   Rose   |    Ana   |  Glenda  |
| age        |    30    |    26    |    24    |    28    |    32    |
| profession |   judge  |  hostess |  singer  |   nurse  |biologist |
| country    |   Peru   |  China   |  Mexico  |   Italy  |   Egypt  |
| duration   |    25    |    15    |    20    |    5     |     10   |

HOWEVER, @dcfyj points out in the comments that Machu Picchu isn't in China, it's in Peru. So therefore the person with the white purse should be going to Peru. However that doesn't work, so I think the website has made a mistake.

I was timed and it took me 13 minutes. Adding Step by Step now

STEP 1: Back to Basics

First we should find the basic clues, the definites. The basic clues here are:

1, 12 and 15

GRID:

|            | Woman #1 | Woman #2 | Woman #3 | Woman #4 | Woman #5 |
|------------|----------|----------|----------|----------|----------|
| purse      |          |          |          |          |          |
| name       |          |          |          |          |          |
| age        |          |          |          |          |          |
| profession |  judge   |          |  singer  |          |          |
| country    |          |          |          |          |          |
| duration   |          |    15    |          |          |          |

STEP 2: Infermiera

We know from the common statement in 10 and 13 that the Nurse is going to Italy. We also therefore know from statement 2 she is either person 4 or 5.

STEP 3: Queen Ana IV

From Step 2 we can work out that Ana is the fourth person. We know she is left of the biologist, meaning she can't be in fifth. We also know that the hostess is between someone from statement 14, so she can't be 5th.

So now there are two possibilities:

• judge - biologist - singer - hostess - nurse
• judge - hostess - singer - nurse - biologist

If we go with the first option, then that means that the fifth person has to have a blue purse from rule 14, but that contradicts rule 19 so the correct way is the second:

GRID:

|            | Woman #1 | Woman #2 | Woman #3 | Woman #4 | Woman #5 |
|------------|----------|----------|----------|----------|----------|
| purse      |          |          |          |          |          |
| name       |          |          |          |   Ana    |          |
| age        |          |          |          |          |          |
| profession |  judge   |  hostess |  singer  |   nurse  |biologist |
| country    |          |          |          |          |          |
| duration   |          |    15    |          |          |          |

STEP 4: Lara Judges a Nurse in the Blue

Lara is person 1 from rule 14, and blue purse must be person 4 from 2 and 19. Rules 2 and 13 also mean that person 3 travels for 20 days.
