Question

_+_+_=30 using only this numbers (1,3,5,7,9,11,13,15)

Answer 1

As we can see that 3 odd numbers are to be added in such a way that their sum comes 30 …

Sum of 2 odd numbers is always an even , so when we add another number to it , it will become an odd number . So they cant be solved by just adding 3 numbers . And that is what made it famous.

Our plan should be that we need to make a number even such that (even)+(odd)+(odd)=30 .

So it can be …

(1+3) + 9 + 7 =30 (by adding)

11 + 13 + 3! = 30 (by multiplying or factorial)

(7-1) + 11 + 13 = 30 (by subtracting)

13.3 + 5.7 + 11 = 30 (by decimal using numbers 13,3,5,7,11)

Answer 2

Answer:

3!+11+13= 30

(3!= 3×2×1= 6)

6+11+13=30
