It is not possible........................................................................

No it is not possible because the sum of three odd numbers can never be an even number .. all the numbers on the balls are odd numbers and thirty is an even number so it’s not possible to select any three balls which add up to fifty 
						

							
yes it is possible. 11+13+6(by rotating the 9 number ball upside down) = 30

No it is not possible to get an even number on adding 3 odd numbers.
But by rotating the ball 9 which is equal to 6,
11+6+13=30
						

							
Dear student 
The no , 9 can be used as number 6 because it is sphere , so it is very much possible to make sum = 30 by doing this . 
Hope this will help 
Good Luck 
						

							
No because the sum of three odd numbers can never be an even number and in the given figure all of them are odd numbers so it is not possible but if the ball which has the number nine is rotated and becomes six then it is possible 11+13+6=30 so the sum of any three numbers in the given image can be thirty
 
						

							
No , there are no such 3 numbers whose sum adds up to 30.
However , if we flip the number 9 upside down , it would be 6 as the ball is spherical. Hence 11+13+6=30
