If 2 is added to each even digit and 2 is added to each odd digit in the number 7145362, what will be the sum of the last two and first two digits in the new number thus formed?
Given: 7145362
Logic:
Even digit → +2
Odd digit → +2
Original | 7 | 1 | 4 | 5 | 3 | 6 | 2 |
Even / Odd | Odd | Odd | Even | Odd | Odd | Even | Even |
New | 9 | 3 | 6 | 7 | 5 | 8 | 4 |
The sum of the last two and first two digits in the new number:
9 + 3 + 8 + 4 = 24
Thus, the correct option is (B) 24
