Question

1,3,5,7,9,11,13,15,17,21,23,25,27,29 this noumber 3 tym s add give 30 how

Answer 1

Final Answer : There is no such number which gives 30 here.


Steps:
1) Set A = Odd Numbers ={1,3,5......29..,etc.}
We have to find (x, y, z)
such that
$x + y + z = 30 \: : (x, y, z) \in A$


We know, 30 is an even number .
and x, y, z are odd numbers.

2) We know, Sum of any three odd numbers can never be even.
Hence, There is no such (x, y, z) which satisfies
given relation.

Answer 2

It is not possible. Because  sum of 3 odd nos will be odd.

As 30 is an even number, it is difficult to make 30 by adding these odd numbers i.e. odd + odd = odd.

All the given numbers are odd and so any possible sum of three numbers taken from this set would be odd whereas 30 is even.
