In a certain code language, 56789 is coded as 13579, then what will 78365 be coded as?
Options:

Correct option is B

Ans. (b) Sol.
To understand the pattern, let's first look at how 56789 is coded as 13579. Observe the pattern in the digits:
· 5 → 1
· 6 → 3
· 7 → 5
· 8 → 7
· 9 → 9
So, each digit in the original number is reduced by a certain value:
· 5 is reduced by 4 to become 1.
· 6 is reduced by 3 to become 3.
· 7 is reduced by 2 to become 5.
· 8 is reduced by 1 to become 7.
· 9 remains the same as 9.
Now, applying the same pattern to 78365:
· 7 → 3 (reduced by 4)
· 8 → 5 (reduced by 3)
· 3 → 1 (reduced by 2)
· 6 → 5 (reduced by 1)
· 5 → 5 (remains the same)
Thus, 78365 is coded as 35155.
