Can some one help me with these questions
(2[32]10) (5[23]6)
(4[ ? ]12) answer is 40
(9[11]15) (12[14]18)
(6[?]12) answer is 8
Analogies
Don't understand these ones and how to explain my 10year old

Snow is to [stone flake crystals] as steam is to [cloud rain vapour]
Answer is crystals, vapour
Prompt is to [ rapid slow dull] as delay is to [eject detain forlorn]
Answer is rapid, detain
Thanks

2nd one: Plausible working would be 1 less than the average of the 2 numbers

2nd one. Add the 2 numbers together, take away 2 and halve it.
(9[11]15) (12[14]18)
(6[?]12)
9+15=24-2=22/2=11
12+18=30-2=28/2+14
6+12=18-2=16/2=8
Hope this helps.

Snow is rain forming crystals when cold, steam is water forming vapour when hot.
Please return my books promptly/rapidly. I was delayed/detained coming through the airport.

I thought that originally romys but it doesn't work for the third one (answer 8 ) and if 9 is not in the 5 choices...

Is this multiple choice? It could be more than one answer for the second question.


Hi belinda..i thought it still works...average is 9 and 1 less than the average is 8...


usually the solution should be straightforward and hence i wanted to play around the average :)

1st one: 2 + 10 = 12 + (2 * 10 (second number)) =32
5 + 6 = 11 + (2 * 6 (second number) = 23

4 + 12 =16 + (2*12) = 40

2nd one:

9 + 15 = 24 - (2nd number 15 - 2) = 11
12+18 = 30 - (18-2) = 14

6 + 12 = 18 - (12-2) = 8
