    Solution

    Let total number of gold movie tickets available in theatre C be 100x. Total number of gold movie tickets available in theatre A = 120x Total number of gold movie tickets available in theatre B = 140x Number of gold movie tickets sold by theatre A = 120x × (20/100) = 24x Number of gold movie tickets sold by theatre B = 140x × (40/100) = 56x Number of gold movie tickets sold by theatre C = 100x × (60/100) = 60x Now, (24x + 56x + 60x)/3 = 280 => 140x = 840 => x = 6 Total number of gold movie tickets available in theatre B = 140x = 840
