Can U solve this

All the numbers supplied are ODD.
The sum of three odd numbers will surely be odd -
whether or not they are repeated!
So what is the solution anyway???
It is assumed that ZERO can't used
nor any negative integer! Right???

I also concur with your reply. How then Mr gaurav agarwal could solve. Let Mr.Viswanathan come out with the answer.
There is no restriction provided on the use of mathematical symbols and their functions. So a probable answer could be:
[13-1] + [13-1] + [13-7] = 30
Also I cant understand why should WE be glad that only Gaurav Agarwal, the IAS topper could solve it..?
Oh boy! I bet I am very glad that our dear Mr. Zee has solved it ! :clap2:
The use of (-) opens up many possibilities I am sure.
Let me work out and give the other solutions if they do exist!

How about this instant solution???
(15-5) + (13-3) + (11-1) = 30
(15-5) + (13-3) + (11-1) = 30
(15-1) + (13-3) + (7-1) = 30.
I am sure there may be many more solutions!
Hats off to Mr. Zee ( Long time no see!) :yo:

Hats off to Mr. Zee ( Long time no see!) :yo:
(15-11)+ (13-9)+ (11+11)= 30.
(15-9)+ ( 13-7) + (11+7) = 30.
Now I understand why the odd numbers are selected so beautifully!

This new thread shows that dear members have missed this thread Can you ? dated 1-10-15
and these two posts!! :ranger:
and these two posts!! :ranger:
Entering forum after a break!
There is no way to have ONLY three numbers because all the numbers are odd
and three of them will NEVER give 30 as total! :nono:
I thought of 15 + 13 + (11 - 9) and many other combinations with one minus symbol.
Eg:
15 + 11 + (9 - 5)
15 + 9 + (7 - 1)
15 + 7 + (13 - 5)
15 + 5 + (11 - 1)
and so on...................
But............. Google search gave the BEST answer using all the numbers!
15 + 13 + (11-9)/(7-5)*(3-1) = 30
WOW! Brilliant !! :clap2:

Why so much in love with number 13??
What is 'unlucky' for many is very 'lucky' for a few? :decision:

Nobody is answering my main question, which is :
Why should WE (tambrahms) be glad that only Gaurav Agarwal (IAS topper) only could solve it..?
If Zee"s formulae is the best solution, many more of us could also solve this problem in the same way. Anyway kodos to Mr.Zee.

:lol: So, you too missed the earlier thread in which some had answered! :ranger:
Why is PJ Sir (the original thread poster/master) missing in action?
15 + 15 + (1-1) = 30
15 + 15 + (3-3) = 30
15 + 15 + (5-5) = 30
15 + 15 + (7-7) = 30
15 + 15 + (9-9) = 30
15 + 15 + (11-11) = 30
15 + 15 + ( 13 - 13) = 30
15 + 15 + ( 15 - 15) = 30
The last solution uses just one number "15" !
15 + 15 + (3-3) = 30
15 + 15 + (5-5) = 30
15 + 15 + (7-7) = 30
15 + 15 + (9-9) = 30
15 + 15 + (11-11) = 30
15 + 15 + ( 13 - 13) = 30
15 + 15 + ( 15 - 15) = 30
