If in a coding system 38474 is coded as 47565, then how will 28464 be coded in the same coding system?
Answer & explanation
Correct answer: option 3
The logic here is;
38474 = 47565
3 +1= 4
8 -1= 7
4 +1= 5
7 -1= 6
4 +1= 5
Similarly,
28464 = ?
2 +1= 3
8 -1= 7
4 +1= 5
6 -1= 5
4 +1= 5
Thus, 37555 is correct.
