Which are which?
1. This is a numbered list of twelve true-or-false statements.
2. Exactly three of statements 7-12 inclusive are true.
3. Exactly two of the even-numbered statements are true.
4. If statement 5 is true then statements 6 and 7 are both true.

Too difficult? 😛
edit: But your right, in the minutes when I tried him, he was very difficult! 😛

Below are twelve statements that are either true or false.
Which are which?
1. This is a numbered list of twelve true-or-false statements.
2. Exactly three of statements 7-12 inclusive are true.
3. Exactly two of the e ...[text shortened]... e.
12. Exactly four of the other statements are true.
The solution is: 1 and 5 are true
T 1. This is a numbered list of twelve true-or-false statements. easy , of course it's true
F 2. Exactly three of statements 7-12 inclusive are true. none of them
F 3. Exactly two of the even-numbered statements are true. none of the even-numbered
F 4. If statement 5 is true then statements 6 and 7 are both true. 6 and 7 aren't both true
T 5. Statements 2-4 inclusive are all false. that's true
F 6. Exactly four of the odd-numbered statements are true. 2 of them
F 7. Either statement 2 or 3 is true - but not both of them. both false
F 8. If statement 7 is true then statements 5 and 6 are both true. 7 is false so then this doesn't matter (or am I wrong here??? now I look for second time this one is true... because IF 7 is true then those would must be true, but 7 is false...)
F 9. Exactly three of statements 1-6 inclusive are true. 2 of them
F 10. The following two statements are both true. both false
F 11. Exactly one of statements 7, 8 & 9 is true. all false
F 12. Exactly four of the other statements are true. just 2
I'll edit this one soon for the correct solution
EDIT:
This is the solution (I hope)
1, 3, 4, 6, 7, 11 are true
T 1. This is a numbered list of twelve true-or-false statements. true
F 2. Exactly three of statements 7-12 inclusive are true. Just 2
T 3. Exactly two of the even-numbered statements are true. 2 and 4
T 4. If statement 5 is true then statements 6 and 7 are both true. 5 = false
F 5. Statements 2-4 inclusive are all false. 2 = true
T 6. Exactly four of the odd-numbered statements are true. 1,3,7,11
T 7. Either statement 2 or 3 is true - but not both of them. 2 = false, 3 = true
F 8. If statement 7 is true then statements 5 and 6 are both true. 7 = true, but 5 = false
F 9. Exactly three of statements 1-6 inclusive are true. 1,3,4,6 so 4
F 10. The following two statements are both true. 12 = false
T 11. Exactly one of statements 7, 8 & 9 is true. 7=true 8,9=false
F 12. Exactly four of the other statements are true. 6, 1,3,4,6,7,11
I don't like this any more today 😉 It took me more than 100 minutes... It's a great difficult puzzle, a bit to difficult for 1 day... But I promised

Well done, Florrat.
(Pity you didn't give any method.)
---------------------------------------
Debra said to Bernie: "I am 9 years older than Ella."
Ella said to Bernie: "I am 7 years older than Ava."
Ava said to Bernie: "Your age is precisely 70% greater than mine."
Bernie said to Carla: "Ella is younger than you"
Carla said to Debra: "The difference between our ages is 6 years."
Carla said to Ava: "I am 10 years older than you."
Carol said to Ava: "Bernie is younger than Debra."
Bernie said to Carla: "The difference between your age and Debra's age is the same as the difference between Debra's age and Ella's age."
Given that all of the above ladies spoke truthfully when talking to an older woman and lied when talking to a younger woman, what are their actual ages?
