One of the Turkish way of saying that is;

Allah bir yastıkta kocatsın (for your "allah bless your marriage" part and it means that your are hoping the married ones will be togather untill the day they get really old. However that is an old saying and young generation do not use it often)

Evliliğiniz boyunca tüm güzelliklerin sizinle olmasını ve mutluluğunuzun baki kalmasını tüm kalbimizle dileriz. (for the rest of your sentence)

Another one (I hope you do not search for these on google )

Uzaktan baktım hiç yok yakından baktım pek çok

Translations and answer

Yes it is a very simple riddle. And your way of translations is correct.  However in the Turkish sentence the question sounds more elusive to catch than your english translations. Thanks for your correct answer

This is a Turkish riddle that some elders used to like ask kids. Who can translate it into english and give me the answer? Good luck.

Beşi beş kuruştan beş yumurta kaç kuruş eder?

Seni ariyorum : You might use that when you have been searching for someone for a while.

Like:  Ne zamandır seni arıyorum. Nerelerdesin?  I have been looking for you for along while. Where have you been?

Some people also use it like they will be calling someone in a future time frame

Like this : O zaman yarın sabah seni ariyorum :  So, I will be calling you tomorrow morning.

But this is I think just what the everyday language is like.  Seni arıyorum is grammitcally means I am calling you. You can ofcourse also use it in a current time frame.

I hope that makes sense. (and i modified my first reply. dont forget to check it mate)

1-This evening i will call you - Bu akşam seni arayacağım

2-This evening i will be able to call you - Bu akşam seni arayabileceğim.

*This second sentence is alittle bit tricky infact. The exact english translation is Bu akşam seni arayabiliyor olacağım.  However this is gramatically correct  no one would say that or you can use that in a very rare situation that i cannot think of right now.

*You can also say Bu akşam seni arayabilirim (This includes alittle bit of unsureness.) like bu akşam seni araya da bilirim aramaya da bilirim, if that  makes any sense.  Infact the context of the dialogue is what determines which one you would like to say.

3-This evening i am calling you-Bu akşam seni ariyorum.

So your first sentences tense is wrong. Hope this will help you...
