25th August Gre Quants Question

If AB = BC, CI = IH & DE = EF then
Col A: Area of Rectangle GDEF
Col B: Sum of areas of Rectangle ABCD & CIHE

2. What is the closest integer to sqrt(171)?

3. If an = n { (-1)^n – 1)}, and a1, a2, a3, a4, a5 are the terms then what is the difference between greatest & least term?

4. No. of Members Least weight Range
20 members 100 29
21members 130 35
When two groups are joined, what is the median weight of the group?

5. Col A: 0.9999/0.9998
Col B: 1.0002/1.0001

6. If (2x+7) < 13 then
Col A: x^2
Col B: 9

7.

If AC = x, then find the perimeter of the figure?

max wt. of 20 members 129
max wt. of 21 members 135

total no of members 41
therefore median wt--21st wt

20th wt = 129
21st wt= minimum of wt of 21 members

therefore 130.....(hope.u considering the fact that wt's have to be arranged in ascending order.. )
