Question

If 2 is added to each even digit and 1 is subtracted from each odd digit in the number 945217, then what will be the sum of number/numbers not repeated in the new number?
1. 6
2. 8
3. 4
4. 5
5. 7

Answer 1

Correct Answer - Option 2 : 8

Given: 945217

By adding 2 in the even digits and subtracting 1 from the odd digits, we will get,

Number	9	4	5	2	1	7
operation	-1	+2	-1	+2	-1	-1
New Number	8	6	4	4	0	6

Here can clearly says that 8 and 0 are not repeated.

Therefore, sum of the number = 8 + 0 = 8

Hence, "8" is the correct answer.
