5+3+2=(5*3)(5*2)(5*3+3*2) We get (5*3+3*2)=21 rewriting 21 as 12 as 2+1=1+2 we get 5+3+2=151012 Similarily,9+2+4=183662;8+6+3=482466;5+4+5=202504 & 7+2+5=(7*2)(7*5)(7*2+2*5)=1435(14+10)=1435(24)=143542.It is from Quantum Section of CAT.Make use of Boolean Algebra.It can be solved using OR & AND Gate.Part of De-Morgan's Laws.It took just 10 seconds to solve!!!
