Col B: (149!*148!-148!)/147!
2. An area of 1350 is given whose length is 15yards more than the width. Calculate the amount of wire needed for fencing in yards?
3. In a college of 700 students, 200 choose maths, 350 choose science, 250 choose history, 150 choose both science and math and 100 chose neither. Calculate the number of sophomores who chose all three?
4. If x and y are positive even numbers, then
Col A: (-1)^(x+y)/2
Col B: (-1)^(x+y

4th quest i think D will come..
If u select x=2 & y=4 then B is greater
If u choose x=4 & y=8 then C is coming
So ans must be D.
Pls reply i have a gre on 12th.. -

9. If x < 0, then
Col A: [x]
Col B: -x
assume x is -1
col a mod(-1)=1
colb -x =-1
so col a is greater
please correct me if i am wrong -
