HELLO DEAR,
we know that it is impossible to get a even number by adding three odd numbers.
------------------(1)--------------------
if we know the factorial
we can also solve by using factorial
3! =3×2×1 =6
(11) + (13) +(3!) =30
---------------------(2)---------------------
we can also do like that:-
(1+9) + (3+7) +(5+5) = 10 + 10 +10 =30
I HOPE ITS HELP YOU DEAR,
THANKS

Hey there!
A similar question is already posted by one of our brainliac and is answered by me.
brainly.in/question/1152794
https://brainly.in/question/1183248
This question can be solved by binomial co-efficients
we know Ncr =n!/r! (n-r)!
5!=120
3! =6
2!=2
So 5c3 =5! /3!(5-3)!
=> 120/6*2!
=> 120/6*2
=> 120/12
=> 10
Finally,
=> 15+5+ [ 5C 3]=30
=> 15+5+10=30
hence proved !
It is so easy
