Instructions: Each question consists of a problem followed by two statements. Decide whether the data in the statements are sufficient to answer the question. Eshan and Arnob have the same birthday. Arnob's age now is the same as Ehsan's age was when Arnob was half as old as Ehsan is now. What is Ehsan's age now? (1) Ehsan is currently four times as old as he was when Arnob was born. (2) Ehsan was six years old when Arnob was born.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statement TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statement (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.
Explanation: Statement 2 দিয়ে possible। Ehsan = \(x\), Arnob = \(y\). \(x = y + 6\) (from Statement 2). Arnob is now same age as Ehsan was when Arnob was half as old as Ehsan. Arnob = \(x/2\). Ehsan = \(x/2 + 6\). Arnob's age now \(y = x/2 + 6\). \(x = y + 6\) এবং \(y = x/2 + 6\) solve করে পাই \(y = 18\), \(x = 24\)। Statement 1 দিয়ে ওদের age বের করা সম্ভব না।
