(1+9)+(3+7)+(5+5)=30
8 3 8
(1+9) + (5+7) + (7+1) will also do
ya
(1+9) is a threshold point. addition of any number further gives 30
it is impossible to get an even number by adding three odd numbers. so, odd + odd + odd =/= 30 hence it is an impossible event It is possible only in case of factorial. 3! + 15 + 9 = 30 3! + 11 + 13 = 30 3! Refers 3x2x1 = 6 In odd number it can be represent as 3!
