    Eduncle Best Answer

    Let the price of single glass is G and of Cup is C , same for Pencilbox P.
              G + P + C = 21  ...(1)
              G + 2P + C = 28 ...(2)
              2G + 2P + C = 35 ...(3) 
    Subtract 2 from 3 we get G =7. Subtract 1 from 2 we get P = 7. 
      Put value of G and P into (1)
    We get, C = 7. 
      Hence, Cost of 10 cups is Rs. 70
