Answer: is 65292
1.Three pairs of digit sum up to 11
So.5+6,4+7,3+8,2+9
So, password must consist of 2 to 9 numbers to make a pair 11.
No 0 or 1.
2.Also it has only 5 digit. So any two number must be same.
3. as per other condition.. 1st and last digit can't be same and also 3 middle digits can't have 2 same number.
4. Last and first digit can be
6___2
9___3
No other options suit for three times the last digit.
5. For middle numbers..
_529_ is the only option and 2 is a repeator that can make third pair as sum of 11.
_63(11)_ error and also 6 is a repeator but it can't make sum as 11.. Anyway error case.
_74(12)_error also no repeators
So.. Now from step 4 and 5..
65292 is the password.
Hard choosing from "A" to "D", but my best answer that I came up with is "D" or "4"
The word "Who's" is a plural and actual stands for "Who is" So if you put that in that sentence "Who is book about blue whales is this?" Or for "2" the word "Whomever's" doesn't make since in the sentence.. "Whomever's book about blue whales is this?" And the same with "3". But with "4" "Whose" It fits in that sentence.. "Whose book about blue whales is this?" It's best if you read the sentence out loud and see which word best fits in that sentence.
