  1. Thanks a lot for your prompt reply, kindly please send me the file to ajai.teralab@gmail.com Thanks.
  2. Congrats dude......well done ! Could you please post us the URL that has all the sets discussion.
  3. Awesome score dude ! Bob800 might provide the insight...........
  4. 1) is definitely E and (2) is incomplete
  5. I am not aware of the perfect procedure but I would pick my answer as (5). I assume 'm' is the total value of the expression. Here is my reasoning : The first term 4^(1/2) = 2 and the last term 4^(1/4) = sqrt(2)= 1.414 then the middle term 4^(1/3) definitely must be something less that the first term. So I will put this as around 1.5 => 2+1.4+1.5 => something around 5 but definitely greater that 4. Could you please post the OA?
  6. IMO :B "residents of" not "residents from". A and C are out. Jobs not job ( He cant offer single job to all the residents), hence D and E are out. I also vaguely remembers the idiom as "so moved......as to"
  7. A tricky question, one might guess that answer is B thinking that set is of infinite multiples of 4 and hence superset is also an infinite set with multiples of 3. So the answer will be NO, it is not a superset. But we should remember that multiples of 4 might be of only even numbers with no odd things (i.e) { 4,8,.......} Good going Jay.
  8. Wow ! Amazing score buddy ! Congrats ! Waiting for ur debrief !!
  9. Quite overloaded with work since 3 days......not even getting a chance to take a look at this forum. will give a test and decide in this long weekend. How abt u ?
  10. I remember it as a(1-r^n)/1-r. U miscalculated it Jay. 2 + 2(1 -2^(8+1)/1-2 ==> 2+2-2.2^9 = 2^10
  11. AK, Yup you are right we can do that. You have a great insight buddy. [clap] But we are not bothered abt the other side, we need the height. I did it as follow : Angle BCE = 135 Extend the line BC towards the other side of B and draw a straight line from E to touch the extended line,let this be point "X" now this(EX) will the height of BCE. We know EC=1, Angle ECX = 45 (180-135) so EX = > sin45=EX/1(opp side/hypotenuse) => EX =1/root2 Hence the area = 1/2*1*1/root2.
  12. Hi AK, I am confused with this problem, could you please post the solution how you are able to solve this using trig ? Thanks dude.
  13. Its simple : 1/5^m = 5^-m 1/4^18= 1/((2)^2)^18=2^-36 1/2(10)^35=1/2(2*5)^35=>1/2*2^35*2^35=>2^-1*2^-35*5^-35=>2^-36*5^-35 => 2^-36*5^-m = 2^-36*5^-35 Hence m=35 HTH
  14. Total outcomes = 5! = 120. P(no couple sit together)=1-P( atleast one couple sits together) P(atleast one couple sits together)= consider for first couple sitting together : Bind them in to single entity. so now we have only 4 persons (husband and wife are one) and 4 chairs (one chair less as as we are considering husband and wife as 1). 4 people can be selected in to 4 chairs as 4! and husband and wife can be bundled in as 2! ways Hence = 4!*2! = 48 Same as the case for second couple Hence = 4!*2! = 48 So total = 48+48. But we have counted the couples sitting together once in first couple and also in the second couple calculation. Hence remove it one time. For that we need to calculate both couples sitting together count. Now bundle a couple in to a single entity and another couple in to a single entity . Now we have 3 people with 3 chairs. Hence 3! ways and the couples can be rearranged them selves in 2! ways. For both couples it is 2!*2! = > 2!*2!*3!= 24 So now our possible outcomes are 48+48-24 = 72 => 1-72/120 = 2/5 HTH
  15. Yes buddy, If you can express a number as 2^x*5^x then those numbers will have the finite decimals. I think answer might be C. A) insuff as we dont know the denominator B) Yes, for every value other than P=8. If P=8 then it is "1". If we take A+B) then P=8 is ruled out, correct me if I am wrong.
  16. How abt 6+16+16+16+16+16+16 = 102 ??? satisfies : 7+ve numbers and range =10
  17. Let I be the children with inflamation(few may have fever also) Let F be the children with fever (few may have inflamation also) Let x have both We need (I-x) From A) 1000-880 = 120 = I+F-x ( as x is the number affected by both) insuff From B) F-20 insuff A+B) I+F-x=120 => (I-x)+F =120 => I-x+20=120 =>I-x =100 Hence answer is C HTH By the way, Jay did you take full prep test > how much did you get ?
  18. I will go with D. X is primarily planters(vegetation) fishing and hunting (non-vegetation) we need contrast word here with simple past as the tense of the sentence is in past. A, E -- presentence B -- past perfect ( There are no two time frames here to use a simple past and a pastperfect) c -- second phrase shouldnt be independent, it should depend on first Wat is the OA ?
  19. Yup, my bad. Thanks a lot Valentino. D seems more illogical to me now, stating "community posseses 50% of the income". ;-(
  20. Thankont, You have left incomplete, this might confuse others : After x=2, y=3 for ii) let x=2, y= -3 then |2|-|-3| = -1 and |2-(-3)| = 5 , now also inequality holds good. Hence x=2 and y=3 (both x and y are positive) (ii) holds good but xy x=2 and y=-3 ( x is +ve and y is -ve) (ii) holds good but xy Hence conflict and we cant decide. Remember if you can say NO to xy I guess I make sense.
  21. It's simple. Let the total number of motorists =100 the number who exceeded the limit = x 10% exceeded and got ticket => 10% of 100 = 10. 20% of motorists who exceeded didnt get ticket => 20% of x (who exceeded) Now x = 10 (got ticket) + 20% of x (not got ticket) x=10+0.2x 0.8x = 10 x = 12.5 that is 12.5 % of 100(total motarists) and hence the answer is 12 1/2 % HTH
  22. I go with 1)D 2)D 1) A) No parllelism, "langurs" is plural, we need singular because in the last part of the sentence "its" has been used. B) Fails for the same reason c) Fails for the same reason D) singular langur + parllelism (answer) E)fails parllelism. 2) A) to reffer community we dont use "where" rather "which" is used and hence this fails. In addition it says "house hold income of 50%" not "50% of house hold income". B) same reason (where) C) same reason (where) D) where+ 50% of household income (answer) E) Wordy + them has no antecedent.
  23. Its simple : 3T = 1t 4t = 1/4 c => c = 16t 3/8 c = (?)T =>3/8 (16t) => 6 t => 6 (3T) => 18 T HTH
