Yes, there can be many methods and logics to solve these types of questions. But I felt bit uncomfortable with the logic that you used to solve these two questions:
(57 [27] 9) (60 [30] 10)
(54 [?] 8 )
(10 [15] 45) (12 [18] 54)
(8 [?] 36)
I will be surprised if you taught the same logics that you explained earlier to your 11+ students.

Dear Patricia , Ambridge, and all...
Ambridge pleeeeese tell us the answers! Its so hard to make sense of it all otherwise!
Patricia, am I being a dunce here?
(3 [18] 9) (5 [50] 15)
(7 [?] 12)
The method you used to work this out doesnt seem to be working for me!
3 x 9 = 27 subtract 9 [ the number on the right]
5 x 15 = 65 subtract 15 [the number on the right]
7 x 12 = 84 subtract 12 = 72
5 x 15 = 65, subtract 15, number on right equals SIXTY, but the number in the brackets is 50. Am I missing something?

Dear Jays darlin
I am so WRONG! [but always one to admit the errors of my ways!]
I cant even mulitply...
5 x 15 = 75 not 65

I get the following:
"The difference between the two outer numbers" x "the left hand one"
Do we know what the answer actually is?
Is it 35?
