Answer:A Explanation:Total number of Q type cars produced in 2001 =(60 - 40)% of 4,40,000 = 88,000. Total number of Q type cars produced in 2000 =(45 - 30)% of 3,50,000 = 52,500. Therefore Required difference = (88000 - 52500) = 35,500.

Answer:C Explanation:Analysis of the graph: We shall first determine the number of cars of each model produced by the Company during the two years: In 2000 : Total number of cars produced = 3,50,000. P = (30 - 0)% of 3,50,000 = 30% of 3,50,000 = 1,05,000. Q = (45 - 30)% of 3,50,000 = 15% of 3,50,000 = 52,500. R = (65 - 45)% of 3,50,000 = 20% of 3,50,000 = 70,000. S = (75 - 65)% of 3,50,000 = 10% of 3,50,000 = 35,000. T = (90 - 75)% of 3,50,000 = 15% of 3,50,000 = 52,500. U = (100 - 90)% of 3,50,000 = 10% of 3,50,000 = 35,000. In 2001 : Total number of cars produced = 4,40,000. P = (40 - 0)% of 4,40,000 = 40% of 4,40,000 = 1,76,000. Q = (60 - 40)% of 4,40,000 = 20% of 4,40,000 = 88,000. R = (75 - 60)% of 4,40,000 = 15% of 4,40,000 = 66,000. S = (85 - 75)% of 4,40,000 = 10% of 4,40,000 = 44,000. T = (95 - 85)% of 4,40,000 = 10% of 4,40,000 = 44,000. U = (100 - 95)% of 4,40,000 = 5% of 4,40,000 = 22,000. Total number of cars of models P, Q and T manufacture in 2000 = (105000 + 52500 + 52500) = 2,10,000.

Answer:B Explanation:If the percentage production of P type cars in 2001 = Percentage production of P type cars in 2000 = 30%. then, number of P type cars produced in 2001 = 30% of 4,40,000 = 1,32,000.

Answer:C Explanation:Number of S type cars which remained unsold in 2000 = 15% of 35,000 and number of S type cars which remained unsold in 2001 = 15% of 44,000. Therefore Total number of S type cars which remained unsold = 15% of (35,000 + 44,000) = 15% of 79,000 = 11,850.

Answer:B Explanation:The percentage change (rise/fall) in production from 2000 to 2001 for various models is: For P = [ (176000 - 105000) x 100 ] % = 67.62%, rise. 105000 For Q = [ (88000 - 52500) x 100 ] % = 67.62%, rise. 52500 For R = [ (70000 - 66000) x 100 ] % = 5.71%, fall. 70000 For S = [ (44000 - 35000) x 100 ] % = 25.71%, rise. 35000 For T = [ (52500 - 44000) x 100 ] % = 16.19%, fall. 52500 For U = [ (35000 - 22000) x 100 ] % = 37.14%, fall. 35000 Therefore Minimum percentage rise/fall is production is the case of model R.
