Answer:
it is too long plz ask question short
The robbers were girls wearing black outfits.
Explanation:
According to the question, one gave two correct information, and all others gave one genuine and one false.
Here are the testimonies:
A: 6 robbers, having masks
B: No torch, girls
C: Having mask, on foot
D: Grey outfit, having torches
E: On car, boys
F: 5 robbers, black outfit
Let's assume that the robbers were boys. If so, E gave the correct data. [No other informants claim that the robbers were boys].
It establishes that they came in a car (As E gave both information correct)
If they came on the car, the 2nd claim of C is false. So, they had masks.
If they have masks, the first statement of A is false. So, there were five robbers, according to F.
Now, if the first statement of F is true, the second is false. So, they should have been wearing black outfits.
If they wore black, the first claim of D is false. So, they had torches.
But B says they didn't have torches, so the second statement of B has to be true. But the second statement of B is that the robbers were girls. It contradicts our assumption that the robbers were boys.
Therefore, the robbers were girls.
Assume that they wore black.
So, F should be telling the truth. Hence, there should be five robbers.
If there were five robbers, the first statement of A is false. So, they were wearing masks.
If they were wearing masks, the second statement of C is false. So, they came in a car.
If they came on the car, the second statement of E is false. So, they were girls.
Now, if they were girls, the first statement of B is false. So, they had torches.
If they had torches, the first statement of D is false. Hence, they were not wearing grey.
Therefore, we satisfied all conditions. E was telling the truth, and all five had one genuine description and one false.
Hence, our assumption is correct.
Therefore, the robbers wore black.
