Four digits of a number 29138675 are omitted such that the result is as large as possible. The largest omitted digit is:
(A)5 (B) 6 (C) 7 (D) 8 (E) 9Solution follows here:
As we omit 4 digits the left out number is of four digits.
Keep in mind that our target is to get largest number possible.
Come from the left side. 2 can be omitted as it leaves 9 in the left most place.
Similarly 1 and 3 can be omitted leaving 8 for the second left position.
Then the left out digits are 6,7 and 5.
If 6 is omitted, the result is ‘9875’
If 7 is omitted, the result is ‘9865’
If 5 is omitted, the result is ‘9867’.
Omitting 6 gives us largest number.
Finally all the omitted digits are – 1,2,3 and 6, out of which 6 is largest.Answer is (B)
