How is 'DATE' written in the code language ?
Statements:
1. DEAR is written as $#@? in that code.
2. TREAT is written as %?#@% in that code.
3. TEAR is written as %#@? in that code,
Answer: D
Observing 1, 2 and 3, we find that similar letters have similar code symbols at the corresponding places in the code. So, this is direct-coding.
Thus, to find the code for DATE, we need the code for D which can be obtained from 1 only (i.e. $.) and the codes for A, T and E which can be obtained either from 2 or 3 (@, # and % respectively).
