Shankara Setty & co was a jewellery company famous for its artisanship. On a daily basis they received 12 orders for making custom-made jewellery. Of these orders about 20% were for exquisite gold chains that took 5 days to make. The rest were for a pair of designer bangles that took 4 days to make.

 If each gold chain or pair of bangle needed 16 grams of gold, how many grams of gold do Shankara Setty &co have with them at any point in time?
