Answer:
4
Step-by-step explanation:
How many selfies did Tania take? (my first answer would be too many, but that's probably not the answer you're looking for :-) )
We know that each cousin appear 2 or 3 times overall.
If she would have taken each cousin exactly 2 times, that would be 16 cousins/photos
If she would have taken each cousin exactly 3 times, that would be 24 cousins/photos
We know there's exactly 5 cousins per photo...
so we have to find a multiple of 5 cousins/photos that is between 16 and 24.
The only possibility is 20 cousins/photos. 20 / 5 = 4 photos.
If they were all the same number, then each one would be 1/3 of 57. That's 19. All three integers would be 19 ... an odd integer. All you have to do is take 2 away from one of them and glue it onto another one of them, and you'll have your three consecutive odd integers.
The exact answer is 1,166 (and two thirds, but surprise, you can't have two thirds of a person) which I got by dividing 7000 by 6. Simple stuff.
If you need an estimate though you could say something like 1,150, with the explanation that you knew 6 would go into 6000 one thousand times and then into the remaining 1000 about 150 times since a close benchmark, 5, would go in about 200 times, and then just added 1000 times to 150 times to get 1,150
