Explanation:

In a certain code language words are coded as per the following hints.
Find the code for “strike today”?
Statement I: “strike today or never” is coded as “bo ma su no” and “price never today” is coded as “ki no su”.
Statement II: “price strike low today” is coded as “ki bo su pe” and “today sale price” is coded as “su ki ba”.
Checking statement I:
Codes for today and strike cannot be found using statement I alone.
Hence data in statement I alone is not sufficient to answer.
Checking statement II:
Codes for today and strike cannot be found using statement I alone.
Hence data in statement II alone is not sufficient to answer.
Checking statements I and II:
Using first halves of statements I and II, code for ‘strike’ can be found out as “bo”.
Using statement I and II, code for today can be found as “su”.
Strike today is coded as bo su.
Hence data in both the statements is necessary to answer the question.
