    1. Answer: (a) 24%

      Explanation:-
      Demand of color TVs manufactured by company B = 600
      Demand of color TVs manufactured by company C = 2500
      Then, percentage of Company B demand of company C = 600 x 100/2500
      = 24%

      Hence, the answer is (a) 24%.

    2. Answer: (c) 1.80

      Explanation:-
      Production of TVs by company A = 1500
      Production of TVs by company D = 2700
      Then, the number of times the production of TVs by company A = 2700/1500
      = 1.80

      Hence, the answer is (c) 1.80

    3. Answer: (b) 280

      Explanation:-
      The total demand of all companies = 3000 + 600 + 2500 + 1200 + 3300
      = 10600
      Then, the average demand of all companies = 2120

      The total production of all companies  = 1500 + 1800 + 1000 + 2700 + 2200
      = 9200
      Then, the average production of all companies = 1840

      The difference between average demand and average production of TVs all companies = 2120 – 1840
      = 280

      Hence, the answer is (b) 280.

    4. Answer: (a) 3: 2

      Explanation:-
      The number of companies having more demand than production = 3
      The number of companies having more production than demand = 2
      Then, the ratio of the number of companies having more demand than production to that of the companies having more production than demand = 3: 2

      Hence, the answer is (a) 3: 2.
