Answer:A Explanation:Percengate change (rise/fall) in the production of Company Y in comparison to the previous year, for different years are: For 1997 = [ (35 - 25) x 100 ] % = 40%. 25 For 1998 = [ (35 - 35) x 100 ] % = 0%. 25 For 1999 = [ (40 - 35) x 100 ] % = 14.29%. 35 For 2000 = [ (50 - 40) x 100 ] % = 25%. 40 Hence, the maximum percentage rise/fall in the production of Company Y is for 1997.
Answer:C Explanation:Average production of Company X in the period 1998-2000 = [ 1 x (25 + 50 + 40) ] = ( 115 ) lakh tons. 3 3 Average production of Company Y in the period 1998-2000 = [ 1 x (35 + 40 + 50) ] = ( 125 ) lakh tons. 3 3 Therefore Required ratio = ( 115 ) 3 = 115 = 23 . ( 125 ) 3 125 25
Answer:D Explanation:Average production (in lakh tons) in five years for the three companies are: For Company X = [ 1 x (30 + 45 + 25 + 50 + 40) ] = 190 = 38. 5 5 For Company Y = [ 1 x (25 + 35 + 35 + 40 + 50) ] = 185 = 37. 5 5 For Company Z = [ 1 x (35 + 40 + 45 + 35 + 35) ] = 190 = 38. 5 5 Therefore Average production of five years is maximum for both the Companies X and Z.
Answer:A Explanation:The percentages of production of Company Z to the production of Company Z for various years are: For 1996 = ( 35 x 100 ) % = 140%. 25 For 1997 = ( 40 x 100 ) % = 114.29%. 35 For 1998 = ( 45 x 100 ) % = 128.57%. 35 For 1999 = ( 35 x 100 ) % = 87.5%. 40 For 2000 = ( 35 x 100 ) % = 70%. 50 Clearly, this percentage is highest for 1996.
