hi corey, i wud also be delighted to join ur session.PLZ add me [sanin_shining@yahoo.com]

1. modulus(n)=61 modulus(n-1)=62 col A: n col B: 61 ans is B:mad:....anyone has any idea?

for 2nd prob.....point x's absolute value is less than point y's absolute value

1. how 2 solve dis series quickly: 1-(1/2)+(1/3)-(1/4)+(1/5)-(1/6)+(1/7)-(1/8)+(1/9) 2.quantitative comparison: A:100,021*90,120 B:100,120*90,021 how 2 solve dis multiplications quickly?

jess can u plz elaborate how u did it?

jess which values did u choose?

jess can u plz elaborate it :rolleyes: i.e. how u did it.....same for no. 4...thnx

btw does Q like 1 appear on da test?

thnx jesss.......nice method!:tup:

is it D coz x or y intercept could be +ve or -ve? can u elaborate with an example....

for Q1 i think the ans shud be D....since there is no limits for A & B... case1: m=9,n=200 case 2: m=155,n=10 am i right? anyone.....

me too... 1.D 2.A

i'm kind'a flubbergusted :crazy:with these probs....some of them seem easy & doable.....but still confusing....plz enlighten :idea:on how 2 solve these... 1.Col A: The standard deviation of 10, 20, 50, 80, 90. Col B: The standard deviation of 11, 30, 50, 70, 90. any quick method 2 solve sd probs? 2.If [z] represents greatest value less than or equal to z and x & y are positive, then Col A: [x]+[y] Col B: [x+y] i'm always getting c..which is wrong..ans is d...how? 3.If two numbers when divided by 38 leave equal remainders. When divided by 19 the remainders are r and s. Col A: r Col B: s 4. If a number is divisible by 5 the remainder is 3 and when the same number is divided by 7 the remainder is 4. What is the least possible number? 5. Find the probability to get a four digited number with replacement allowed? 6.Given that, if a person has 5 pair of socks of different colors and if 2 are chosen at random then what is the probability that both of them are of same color? ans is 1/9...how? 7.How many different 5 digit numbers can formed, such that 1st and last place should be filled up with odd number. 8.Given that (x^2) + y Col A: (x^2)* y Col B: x* (y^2) 9.Given two sides of a triangle as 10 and 10 & the area of the triangle as 36. Find the height of the triangle? 10.If the average of 'x' spaces of some numbers is 56 and the average of 'y' spaces of some numbers is 56, if 't' lies in the percentile of 60% to 65% of x spaces and 's' lies in the percentile of 70% to 75% of y spaces. Col A : t Col B: s 11.Given that lines 'm' and 'n' are parallel to each other and a line 'k' intersects it. How many points are there in the same plane which have equal distances from all these lines? 12.. When a number is divided by 12, the remainder is 5. What is the remainder when the square of that number is divided by 8? 13.There are 33 balls and 7 boxes. Balls are filled in boxes such that no box is empty and no ball is left. which of the following is necessarily true? (i) there are 5 balls in atleast 1 box (ii) there are atleast 4 balls in every box (iii) there is atleast 1 box with the same number of balls A. Only i B. Only ii C. Only iii D. Both i and ii E. Both i and iii 14.Certain number of balls are kept in 'x' boxes such that each box contains equal number of balls and no box is empty. If there are 3 fewer boxes then 12 balls are kept in each box and 5 balls are left unpacked. What is the value of 'x'? 15.Given P and N are positive integers such that both are not divisible by 4. Col A: The remainder when P+N is divided by 4 Col B: 1 16.A 6 bicylists has to be chosen from 4 adult and 4 children Col A: How many 3 adult and 4 children teams can be formed Col B: How many 2 adult and 2 children teams can be formed

i agree with eghos...

E! can u plz elaborate it step by step plz......i really can't get it:crazy:.....i'm kinda hard-headed for this kind of probs...specially the technics and formula u used kin'da abstruse 2 me....thnx...
