Question


Given that P is a natural number. Is P>1010?
1) P>234
2) P=235


Options:
A .   IF statement (1) alone is sufficient, but statement (2) is not
B .   If Statement (2) alone is sufficient but statement (1) is not
C .   If Both statements TOGETHER are sufficient, but neither statement ALONE is sufficient
D .   If Each statement ALONE is sufficient
E .   Statements (1) and (2) TOGETHER are not sufficient
Answer: Option D
:
D
From statement 1P>234
234=(210)3×24=16×(210)3
Now 210=1024, and 1024 is greater than 103.
Therefore
234>16×(103)3=1.6(1010)
Since 234>1.6(1010)>1010, from statement 1 alone; the answer can be determined
From statement 2P=235
