PRINCESTONE-TV X

by pradeepkaushal9518 » Sun Jul 04, 2010 4:44 am
In City X, a television ratings service estimates that the number of televisions tuned to a certain program represented 44 percent of televisions turned on at the exact time the program was aired. How many televisions in City X were tuned to this program?

(1) There are 1,000,000 televisions in City X.
(2) Fifty-six thousand televisions in City X were turned on but not tuned to the program.



Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.



Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.



BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.



EACH statement ALONE is sufficient.



Statements (1) and (2) TOGETHER are NOT SUFFICIENT

Number of televisions tuned to a certain program = 44% of televisions turned on at the exact time the program was aired

1) insuff - tells us the TOTAL no. of TVs in X but not the no. of TVs which were turned on at the time the program was aired
2) Suff - 56,000 TVs were turned on but not tuned i.e. 56% of total TVs which were turned on at the exact timed the program was aired but not tuned into the program = 56,000. Since this helps us figure out the no. of TVs which were turned on, we can find the no. of TVs that were tuned in to the program

B.

according to me the answer should be C

St-1 is insufficient
St-2 is insufficient as well as it gives onlt the number of televisions turned on and not tuned their is no indication abt the total
which u considered ad 56%(total).....

+1 for B
# of TV tuned to program = 44% TC sets that are switched on at that time (tuned to the program or not )

no doubt b is the answer
the catch in the question is the language -- which can be cumbersome to quickly comprehend under timed conditions

IMO B is the answer as it helps to get an unique value

Number tuned to program at that time = .44* Total tuned at that time. Using the 2nd statement only we know Total tuned at that time at that time and so we can get the value for the number tuned to program at that time .
