Statement 1: The average low temperature for Sunday through Friday was 64 degrees. Statement 2: The low temperature on Saturday reduced the average low temperature for the week by 2 degrees. Which of the statements above make it possible to answer the question? Statement 1 alone is sufficient, but Statement 2 alone is not sufficient Statement 2 alone is sufficient, but Statement 1 alone is not sufficient Each statement alone is sufficient Both statements together are sufficient, but neither statement alone is sufficient Statements 1 and 2 together are not sufficient

Explanation / Answer

Each statement alone is sufficient.

Statement 1: The average low temperature for Sunday through Friday was 64 degrees

No. of days from sunday to friday = 6

Total sum of temp from sun to fri = 64 x 6 = 384

Total sum of temp for sun to sat = 62 x 7 = 434

Temp of saturday = 434-384 = 50

Statement 2: The low temperature on Saturday reduced the average low temperature for the week by 2 degrees.

=> avg. temp of sun to fri = 64 - 2 = 62.

Then, by same method we get temp of saturday.

So, Each statement alone is sufficient.
