-3n^3 = (3n)^3 or, -3n^3= 27n^3 or, 30n^3=0 or, n^3 =0 so, n= 0. if u put n=-1 both side......... L.H.S -3(-1)^3 =3 R.H.S (-3)^3 =-27 so......n=-1 is not a solution

1. Median can be 5 .........consider...... x=4, y=3, z=21 here........average=8, median =5 so, condition 1 need not to be true always. 2. as average....8......and as the 2 given number is less than 8 so one of the x,y,z must be greater than 9. 3. as average 8 and minimum number atmost 5, so again the range must be greater than 2, so condition 3 also holds.

1. let w=1, x=2, y=3,z=4 reminder 1 w=x=y=z=1 reminder 0 2.31= 30+1 17= 15+2 -11=-5+(-6) -13=-10+(-3) -21= ? +? so, answer D 3. Total number =50 perfect square =16,25,36,49 perfect cube = 27 so probability = (4+1)/50 = 0.1

Ans: DEA

sfhad........plzz dont mind.....i think u should not seek answer from any particular person in public forum like that.....if u wanted the answer just from me, u should have asked me privately..... My answer: First prize can be given to 5 persons, second prize to 4 persons and third one to 3 persons. so the answer should be= 5*4*3=60 Sorry.....sfhad........if my remarks r little harsh.

U have calculated probablity.......... ColA asked for the number of ways we can choose. So ColA 5c1*4c1*2c1= 40 Ans: A

awesome man.........ur explanation is so lucid....Thanks.....

1. I m getting 26. first........3 Same digit....... 2c1*1=2 (here 2c1 .....coz we can choose 3 same digit from either 4 or 2 and 1 for as we can arrange them in 3!/3! way) second........2 same and 1 different..............................3c1*2c1*(3!/2!)= 18 last......all r different................................3c3*3!= 6 so......total ways................(2+18+6)=26

Jose......i agree with u for the rest 2.

let minimum num a, then median (a+50), maximum number (a+56) to satisfy the above conditions we need to take x median and x maximum number then we get, (a+(a+50)*x+(a+56)*x)/(2x+1) > (a+50) or, a+ 6x> a+50 or, 6x>50 so, x should be 9 so, total members = 9*2+1=19

Col A the total interest earned on d dollars invested for 3 months at 11 percent simple annual interest. Col B 11/3(d/100)dollars Ans: ColB 2. If 2/3 of the number of women attending a certain dance is equal to 1/2 of the number of men attending,what fraction of those attending are women? a. 2/5 b. 3/7 c. 5/7 d. 3/4 e. 5/6 Ans:3/7 3) Col A. The area of a triangular region with perimeter of 50 Col B The area of a rectangular region with perimeter of 50 Ans: D 4)rack A has 80 pairs of slacks with their price ranging from 12-15 rps per pair and rack B has 60 pairs of slacks with their price ranging from 13-18 rps per pair. By how much maximum value the amount obtained by selling all slacks in rack A is greater than that obtained by selling all slacks in rack B a)300 b)412 c)430 d)520 e)580 Ans: b 79*15 + 12 - 18- 59*13 =412 5). [x] represents the greates integer less than or equal to x and {x} represents the least integer greater than or equal to x. A. ([x] + {x}) / 2 B. 1.4 Ans: D

Here, 13^2 > 5^2+ 11^2 so, x is obtuse angle. so it should be greater than 90.

May be u r right......But its still a cylinder......... What kind of cylinder has volume =K*radius*height ???? if u consider k constant......then infact u r considering pi*r constant. but we can c radius is changing........

Welcome dude. Btw........ur explanation technique is great........ Its great help for us..........keep it up.

Daniel.......2 n 3 r right i guess. btw in the 4th one u have considered 0 as a positive multiple of 3 and 4. Is it right??? I guess its wrong........

[1] A guy throws a pair of dice. If the sum of the numbers on the dice is even, then the person tosses a coin. What is the probability of him getting a head? I guess the answer will be: 1/2*1/2 =1/4 Daniel........i guess u considered seven not even.

I thought u would understand............ Any way for u .....i m elaborating again....though i m not good at it. there r 52 cards. First select a card randomly.........it could be heart, Diamond, Spade or the other one(i forgot the name).At this moment u dont have to think abt probability.Coz the probability to choose any card is 1. Now......let u have chosen a card.... which could be from any of the 4 suits. Ur target will be to get the remaining 3 cards from the same suit, from which the first one has been chosen. so the probability will be.......... (12/51). (11/50) . (10/49) i hope u get it this time..........Its actually same the way others do it.....

I guess....Priyanka n h3qwerty........r right....... I didnt consider atleast first time...... btw whts the answer??

1. 9C6*6C1 2. 6*3*4= 72

Sorry......sfahad_yunas....i didn't find any tricky part in it........... May be they r wrong.

Is the answer 2?? 67= 20+30+25-8-1*2+x x= 2 not sure though.The ques seems confusing..... whts the answer??

I agree with Top_Gun and Denizen. look at the ques.....carefully...... The number of arrangements that can be made from the word MISSISSIPI so that all the S’s come together and the I’s don’t come together is ? the term "all" i guess for both S and I. So we should consider all I's together. 2 or 3 I's are allowed in this case.

sorry......for making complexity. Was it that tough....?? Hope someone will be helped by the explanation........
