we can assume the weights as a,b,c and d and as he mentioned that they are taken in pairs we can relate it as
(a+b)+(b+c)+(c+d)+(b+d)+(a+d)+(c+a)=103+105+106+106+107+109
3(a+b+c+d)=636
a+b+c+d=212
every sum of two no.s is crossing 100 so every no. is greater than or near to 50 so wt can be 51,52,54,55 so minimum is 51
