    SC:E

    -the Democrat implied no inferred from something

    -it = “not care about the plight of the poor”

    PS:D

    1st year: 12000 * 1.1 = 13200

    paid 7000 => pay for 2nd year: 6200 + its interest = 6200 * 1.1 = 6820

  3. From the lesson GMAT:Punch Of the Week (31-May-09)

    Sun, 07 Jun 2009 11:07:58 -0000

    CR: C (because the question ask for the strategy of the advertisement)

    PS: A – 52

    case 1: 23x => we have 10 x case 2: 2×3 => we have 10 x

    case 3: x23 => we have 9 x

    we can switch position of 2&3 => so we have (9 + 10 + 10)*2 = 58

    but 6 duplicate entries found here

    for example 23x and 2×3 both can have 233

    the final result is: 58 – 6 = 52

  4. From the unknown The Ashoka kingdom of India reached far eastern countries of Asia around the third century B.C. , bringing the Buddhist Religion with it from which was derived both the main religions of Myanmar and Japan.

    I can not believe that the answer of this question is “with it the Buddhist Religion, from which derive both the main religions of Myanmar and” The main clause is in simple past, “derive” is in simple present.

    a2+2b=7,b2+4c=-7,c2+6a=-14.

    SUM all: a2+6a+b2+2b+c2+4c=-14

    <=>a2+6a+9-9+b2+2b+1-1+c2+4c+4-4=-14

    <=>(a+3)2+(b+1)2+(c+2)2-14=-14

    <=>(a+3)2+(b+1)2+(c+2)2=0

    =>a=-3,b=-1,c=-2

    =>a2+b2+c2=14

    Sat, 29 Nov 2008 03:52:46 -0000

    _|_F|M|Sum_| A _|_30%X|40%X|70%X_| K|_|_|36__| Sum|_|_100%X|

    => 36 = 30%X => X = 120 Hope it is clear to you

    I got another answer: (1000)2 -> ends by 0, -2×1000x998 -> ends by 0, 9982 -> ends by 6 => the answers will end by 0 – 0 -6 = 4
