• C. If the data either in statement I alone or in statement II alone are sufficient to answer the question.
• D. If the data even in both statements I and II together are not sufficient to answer the question.
• E. If the data in both statements I and II together are necessary to answer the question.

Answer 1

Answer: (E)

If the data in both statements I and II together are necessary to answer the question.

We want to find the number of voters in present election.

From First statement, we have number of voters in last election, lets call it $x$

From second statement, number of voters increased by 15%, so present year number of voters are $1.15x$

Thus, both statement are required to answer the question.

Hence, Option E is correct answer.
