1. Four digits of the number 29138576 are omitted so that the result is as large as possible. The largest omitted digit is (A) 9 (B) 8 (C) 7 (D) 6 (E) 5
tats not the right logic.... take for eg 12349586 i ask u to take off 4 no to make this largest three digit number so according to u it wld be 12345 so i end up with 958
whereas the answer shld be 986
the realise method is.. knock off every small number till the largest number in the largest power of tens place.... in this case its 9 then again knock off all smallest numbers before the next largest number... which is 8... as in more like seeing a graph and selling shares at high... and buying at low...
Option E
