Hi
I think the second sentence should be: "How much must Ali give Abu so that Abu will have $12 more than Ali?"
Total amount of money remained the same after Ali gave some money to Abu.
Total amount of money > $ 54
In the end, Abu will have $ 12 more than Ali,
so, amount of money Ali will be left with > $ (54 12) / 2 = $21
$32  $ 21 = $ 11
Ali must give $ 11 to Abu so that Abu will have $ 12 more than Ali
cheers.

Hi
as it is, the question: "Ali has $32 and Abu has $22.How much must Ali give Abu so that Abu will have $12 more than Abu?" is flawed because "so that Abu will have $12 more than Abu" is meaningless. if I have $100, and I get $10 more, I will have $110 so it is not possible for me to have any amount more or less than what I have at the same time unless I am referring to different time instances eg. "how much must Ali give to Abu so that Abu will have $12 more than what Abu had at first" is possible  just give Abu $12 more then he will have $12 more than what he had at first.
cheers.

Hi
The question was a typo from the centre.
The question goes as
Ali has$32 and Abu has $22.How much money must Ali give Abu so that Abu will have $12 more than Ali?
The solution to this as given by the centre is
If Ali gives Abu some money so that Abu has $12 more than Ali
They have a total of 22+32=54
Ali(in the end)>(5412)/2=21
Ali had $32 in begining
so Ali must give 3221=11
Ali must give $11 to Abu so that Abu will have $12 more than Ali.
