theres no particular answer for this as 3 odd nos. can never make an even no
this can only be solved by logic


11+15+(3+1)
     or
15+9+(5+1)
1 5 1
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!
yup
