Answer 1

Answer:

The total weight is 121/2

Let weight of box A be a

     weight of box B be 7/2 + a

     weight of box C be 16/3 + 7/2 + a          as per given in question

Since total weight = weight of box A + weight of box B + weight of box  C

              121/2        =  a + 7/2 + a + 16/3 + 7/2 + a

               121/2       = 3a + 14/2 + 16/3

                121/2      = 3a + 7 + 16/3

               121/2       = 9a/3 + 21/3 + 16/3

Now by shifting both LCM

363 = 42 + 32 + 18a

289 = 18a

289/18 = a  Ans
