1+3+5+7+9+11+13+15+17+19 are 10 Nos that is equal to 100, choose 5-Nos that are equal to 50 its challange!!?

Question

5-Nos should be amoung given NOS

ie,1,3,5,7,9,11,13,15,17,19

Answer 1

It's not possible. The sum of 5 odd numbers is always an odd number.

Answer 2

it is impossible because

odd+odd=even

odd+odd=even

odd+odd=even

3 even's plus an odd is always odd

so it isn't possible to answer that question using 5 odd numbers

you can answer it with 4 or 6 numbers

Answer 3

a

a + n

a + 2n

a + 3n

a + 4n

5a + 10n = 50

a = 1 .... n = 45/10

a = 2 .... n = 40/10 = 4

2 6 10 14 18 are the five numbers

Actually there are 4 answers. N can be 1,2,3 or 4 makeing a equal 8, 6, 4 and 2 respectively

Well 5 if you count a = 0 and n = 5

0 5 10 15 20

Answer 4

8+9+10+11+12=50

Answer 5

I tried for 10 minutes and I give up.  I tried using a number more than once (because you didn't you say you couldn't do that), and even that didn't work.

We are supposed to use those numbers right?

Answer 6

Suppose, "1" is not amongst those 5 numbers. Then we have a sum of 5 odd numbers, i.e. the result is an odd number. So that it cannot be 50 - an even number.

So 1 has to be amongst the subject 5 numbers. This means the other 4 numbers are odd and their sum is an even number. Once you add 1 to that even number, you'll get an odd number, but 50 is even.

Thus, your task is not feasible to achieve using the pool of the numbers provided.
