Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
1) Let n be 10 then median is 5. Let n be 4 then median is 4 Not suff 2) let n = -1 then median is 1 Not Suff
Only when n < 7 and > 0
when n=-1 the median is 1,but this fails the statement as it is given median>1
hence,n cannot be -1,and n should be greater than 1.
if n=2,median is 2,yes
if n=3,median is 3,yes
if n=4,median is 4,yes
if n=5,median is 5,yes
if n=6,median is 5,yes
if n=7,median is 5,yes
if n=8 or >8 median is 5,yes
If set consists of the nos 1,5,-2,8 and n, is 0<n<7? 1) The median of the nos in S is less than 5. 2) The median of the nos in S greater than 1.
First we need to sort the four known numbers: -2, 1, 5, 8.
1) median < 5. That means n can be placed in the 1st-3nd position, and it should be <5. This implies n can be smaller or greater than 0, or equal to 0. Insufficient.
2) median>1. This means n can be placed in the 3rd-5th position, and it is >1. Again this means it could be smaller than, equal to, or greater than 7. Insufficient.
Combined of course we get 1<n<5. Which means it must be true that 0<n<7. Sufficient.
Keep on asking, and it will be given you;
keep on seeking, and you will find;
keep on knocking, and it will be opened to you.
