here is my take on in.
Basically SP-CP=Profit
case1: 20% profit
96-x=x/5
6x/5=96
x=80
20%(80)=16$ profit
case2:20% losss
Cp-SP=loss
x-96=x/5
4x/5=96
x=120
20%(120)=24$ loss
Case2-case1=24-16=8$ loss
What are the answer choices?

Frank says i took his cookies, btu i didn't take them. --> right

pretty simple man... 1/5=0.2
option 3 is median and what they gave is mean.. so mean <> median.
2(a+b+c+d+e) and moving decimal place by 1 is nothing but 1/5=0.2
Hope you got it.
So answer is C.

okay here you go:
The only number which satisfies the given condition is : 101
and a(n)=a(1)+(n-1)d
199=100+(n-1)d
==> n=100 terms
Probability of selecting 1 number out of 100 numbers is 1/100 hence D

must remeber the following, very easy if you follow the rythm that's going on.
E(+-)E = E
E(+-)O= O
O(+-)O = E
O-E = O
ExE = E
Ex O= E
OxO = O

lets say H-->x and O--y
H/0=2/16=1/8==> y=8x
x+y=144
9x=144
x=144/9=16
==> H=16grams and O=8x=8(16)=128
==>0=128
What are the answer choices?
