Question

1, 3, 5, 7, 9, 11, 13, 15, 17,19 ,21
23, 25,27, 29
add any 3 number we get 30 how​

Answer 1

Answer:

3,21 and 9 after rotating that is:3+6+21=30

Answer 2

Answer:

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

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

so, it can't possible .

but when we use factorial concept , it will be possible. let's take

first number is 9

second number is 15

and 3rd number is 3 !

then, 9 + 15 + 3! = 30

because we know, 3! = 3 × 2 × 1 = 6

hence, we have to choose 9, 15 and 3!

[note :- there are so many possibilities , of we take factorial concept . so don't be confuse]

Hope it helps you and you understood it buddy........................
