Conditions:
(i) If the first element is a symbol and the last, a number, the codes for these two are to be interchanged.
(ii) If the first element is an odd number and the last, an even number, the first and last elements are to be coded as O.
(iii) If both second and third elements are either numbers or symbols, the third element is to be coded as the code for the second element.
How will '%+<25=' be coded?

We follow the given table and code the given combination

Given combination : '%+<25='

​Applying Condition (i):

​The first element % is a symbol and the last element = is a symbol, not a number, so this condition does not apply.

​Applying Condition (ii):

​The first element % is a symbol, not an odd number, and the last element = is a symbol, not an even number, so this condition does not apply.

​Applying Condition (iii):

​Both the second element + and third element <  are symbols, so the third element < is to be coded as the code for the second element +, which is P

The sequence  '%+<25=' will be coded as:

< = P(following condition iii)

So,  '%+<25=' is coded as LPPMBJ​​
