Answer & Explanation 1. Answer: (4) Required difference = (128000 – 107000) = 21000. 2. Answer (3) : From the line-graph it is clear that the productions of Company X in the years 1997, 1998, 1999, 2000, 2001 and 2002 are 119000, 99000, 141000, 78000, 120000 and 159000 and those of Company Y are 139000, 120000,100000, 128000, 107000 and 148000 respectively. Total production of Company X from 1997 to 2002 = 119000 + 99000 + 141000 + 78000 + 120000 + 159000 = 716000. and total production of Company Y from 1997 to 2002 = 139000 + 120000 + 100000 + 128000 + 107000 + 148000 = 742000. Difference = (742000 – 716000) = 26000. 3. Answer: (1) Average number of vehicles manufactured by Company X =1/6 *(119000 + 99000 + 141000 + 78000 + 120000 + 159000 =119333. 4. Answer: (4) The difference between the productions of Companies X and Y in various years is: For 1997 (139000 – 119000) = 20000. For 1998 (120000 – 99000) = 21000. For 1999 (141000 – 100000) = 41000. For 2000 (128000 – 78000) = 50000. For 2001 (120000 – 107000) = 13000. For 2002 (159000 – 148000) = 11000. Clearly, maximum difference was in 2000 5. Answer: (2) Required percentage = [(128000/ 78000) x 100]% » 164%
