Ans.   From TR-10 to A - 10 there is a reduction of 18% in the number of pages. and From TR-10 to TR-9 14% reduction, A - 10 to A - 9 10% reduction.   Assume Test paper in TR- 10 is 100 pages. So in TR- 9 the number of pages are 100X 86% = 86   Now in 14.1-10 total pages are 100 X 82% = 82   Now in 14.1 - 9 total pages are 82 X 90% = 73.8   So total change in the number of pages = (86−73.8)/86×100 = 14.1   14.1nswer 14.1
