Question

[1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 29 ]

இதில் மூன்று எண்ணை கூட்டினால் 30 வர வேண்டும்.
? + ? + ? =30.​

Answer 1

Answer:

in mathematics it is impossible to get an even number by adding three odd numbers.

here 1,3,5,7,9,11,13,15,17,19,21,23,25,27,29 all are odd numbers.

so, it can't possible.

but when we use factorial concept , it will be possible.

lets take first number is 9

second number is 15

and third number is 3!

then 9+15+3!=30

because we know 3! = 3×2×1=6

hence we have to choose 9,15,3!

( note: there are so many possibilities , of we take factorial concept . so don't be confuse)

hope it will helps you

Answer 2

It is impossible but we have a trick.

Explanation:

Here 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 29 all are odd numbers. According to rules of mathematics if we add two odd numbers we will always get a even number and if we add an odd number in an even number we will always get odd number, which means addition of three odd number will  always give odd number and here 30 is an even number and hence this is impossible.

But we have a trick,

If the number 9 is rolled over and make it 6 then we can solve this question very easily.

So, by adding 1,6,23 or 3,6,21 or 5,6,19 or 7,6,17 or 11,6,13 or 13,6,11 we will get our number 30.
