Question

What is the sum of the first seven terms of a geometric progression whose first term is \(729\)? Statements: (I) The seventh term is \(64\). (II) The common ratio of geometric progression is the ratio of the second term to the first term.

• A. Statement (I) alone is sufficient to answer the question, but (II) alone is not sufficient.
• B. Statement (II) alone is sufficient to answer the question, but (I) alone is not sufficient.
• C. Both the statements (I) and (II) are sufficient to answer the question, but neither statement alone is sufficient.
• D. Both the statements (I) and (II) together are not sufficient to answer the question and additional data are required.

Hint:

In G.P. data sufficiency, if any term and the first term are known, use the term formula to find the common ratio first.

Answer 1

The Correct Option is A
