Directions(6-10): Total number of cars sold by a company in six cities is 90000. Given
pie-chart shows the percentage distribution of these cars sold in these cities. The table shows the proportion of three models among those cars sold.

   2205
   2345
   2455
   2184
   2244
   Option D
   T(D) = 90000 *16.8/100 * 4/9 = 6720
   T(E) = 90000 *12.6/100 * 2/5 = 4536
   Difference = 6720 – 4536 = 2184

   31555
   32540
   35660
   30000
   33427
   Option A
   Total number
   = 90000/100[14.3*7/18 + 16.2*5/9 + 18.4*3/10 + 16.8*3/9 + 12.6*2/5 + 21.7*2/10] = 5005 + 8100 + 4968 + 5040 + 4536 + 3906 = 31555

   200%
   235%
   222%
   252%
   288%
   Option B
   M1-D = 90000*16.8/100*4/9 = 6720
   M3-A = 90000*14.3/100*4/18 = 2860
   Required % = 6720/2860*100 = 234.96 = 235%
