Question 34
Exception I:
If a number begins and ends with a non-zero odd digit, then the first and last digits are to be coded as Y and * respectively.
Exception II:
If a number begins and ends with an even digit (including zero), then the first and last digits are to be coded as β and X respectively.
Which of the following numbers can the code YH₹ME* represent?
(A) 138450
(B) 338457
(C) 538459
(D) 438458
Solution
H = 3
₹ = 8
M = 4
E = 5
Now, as per exception I, if a number begins and ends with a non-zero odd digit, then the first and last digits are to be coded as Y and * respectively. Thus, the code YH₹ME* will have an odd digit at the extreme ends.
Thus, it can be 338457 (B) and 538459 (C).
