Answer is D.
My way of solving this is to reduce the general case into a specific case (sorry, algebra!)
Let:
j = 4
Which gives:
k = 20
l = 60
m = 140
0.2m = 28
2j = 8
0.2m/2j = 28/8 = 3.5 = 350% (question asks for percent)
Easy-peasy : )

Is 2l + 2b > 28?
Or, is l + b > 14?
l*b = 50
l^2 + b^2 = 100
or l^2 + 2500/l^2 = 100
or l^4 - 100*l^2 + 2500 = 0
or l^2 = 50
or l = sqrt(50) so b = sqrt (50)
Perimeter = 4*sqrt(50) > 28

X is never removed from the original 8 kg.
X in 8 kg of Y = 2.4 kg
X in 2 kg of Y = 0.6 kg
Total X = 3.0 kg
Final solution = 8 kg - 2 kg + 2 kg = 8 kg
% of X = 3/8 = 37.5%

b. 12 The general approach: 72 = 2*2*2*3*3 = 2*(2^2)*(3^2). If n^2 square is divisible by 72, n must be divisible by SQRT(2)*2*3. Leaving out SQRT(2) since we're only concerned w/ integers, n must be divisible by 2*3=6. Since the rest of the options are multiples of 6, find the largest one which wor...

It's C. Here's a quick-and-dirty way of doing this:
Assume x=50. Now her trip is 50% @ 40 mph and 50% @ 60 mph, so the average speed is midway at 50 mph. See which option gives you 50 mph if x=50. C works, so C it is.

D, without a doubt.
Remember that the word 'for' is a synonym for 'because'. Now the sentence reads, "... because a sacred truce was proclaimed...", establishing how the Olympic Games helped in keeping peace.

Absolute values are positive. The only way two positive numbers can equal 0 is if they are both 0. Neither statement alone is sufficient to establish this, so both are needed.
