Ron puts all his nails into 2 large boxes and 6 small boxes. There are 20 more nails in one large box than one small box. The number of nails in the 2 large boxes was 1/2 as many as the number of nails in the 6 small boxes. Find the number of nails in 1 large box.

* l - large box

 s - small box

* l = s + 20

 * 2l = 1/2 (6s)

   2l = 3s

     l = 3/2s

* [s + 20 = 3/2s] 2

   2s + 40 = 3s

           40 = s

    *       l = 40 + 20

            l = 60 nails
