4(A+B+C+D+E)=408
A+B+C+D+E=102...(1)
Now, taking the 1st 4 sums
A+B=35
A+C=36
A+D=37
A+E=39
Adding.. 4A+B+C+D+E=147...(2)
(2)-(1)...
3A=45
A=15
Where am I going wrong?

I too had taken it as A =15 ..as the answer but if u take A=15 and calculate the rest values of B,C,D,E.... on rechecking some combination of weights are not coming
