It is impossible to get the result of 30 using just odd numbers in the blanks.
Using factorials, we get 3! + 11 + 13 = 30 or 3! + 9 + 15 = 30
Solution:
----- + ------ + ------- = 30
We have to fill with numbers 1, 3, 5, 7, 9, 11, 13, 15 to get 30
We can also repeat the number
Given are the set odd numbers like 1, 3, 5, 7, 9, 11, 13, 15
We need three numbers to fill in the box to get 30
When three odd numbers are added, it results in odd number
But we should get 30, which is a even number
So it is impossible to get the result of 30 using just odd numbers in the blanks.
Using tricks, some of solutions are:
We can use factorial
3! + 9 + 15 = 6 + 9 + 15 = 30
Or
3! + 11 + 13
So, 6 + 11 + 13 = 30
