Awesome score :) Congrats !!!!!

Congrats :)

Congrats Dr.Nishi :) You mentioned that there are only around 20 -25 error types.....Do you have a list of them by any chance. If you do please mail it to me at nyssa21@gmail.com

The Units digit of 7 are cyclic - (7,9,3,1 ) 7^12x => Units digit is always 1 for all positive integers of x. 7^(12x + 3) => Units didgit will be 3. 3+3 = 6 6/5 => Rem is 1.

Congratulations !!!

Answer is B. I did using a different method . But i liked tarkumar's method. I never new about the formula relative distance = relative velocity * time

bh cant be 10. As there are two sides with areas as bh and since sum of areas of any two of the faces of the solid is 50, (bh + bh = 20) is not correct. Hence it should be 25.

I agree with shooter. The answer is C

Statement 1: Sufficient The range will not change if the set has only positive numbers. Ex: S = {1,2,3,4 } Here Range is 3. Adding this number to the set will not change it. Statement 2: Insufficient T = {-1, 0, 1, 2, 3, 4} Here range is 5. Adding this to the set will change the range to 6. Mean of this new set is 15/6 which is less than the range (6) Hence the Answer should be A What is the OA ?

Answer is A

Answer is A

Answer is correct. The OA is B. Thanks :)

Kirri, It says they are not affected by diseases and not free of diseases.

Tom is arranging his marble collection in a collector’s case. He has five identical cat-eyes, five identical sulphides, and three identical agates. If he can fit exactly five marbles into the case and must at least have one of each type, how many different ways can he arrange the case? A. 120 B. 150 C. 480 D. 1260 E. 2520 Please explain how you got the solution. will post the OA soon.

I assumed we are throwing both the die at once. then (3,6) and (6,3) are the same right ?

My guess is C. What is the OA ?

IMO E. What is OA?

CONGRATS :) Awesome score !!!

I agree with Annihilation. Answer is E After reading ramzrambo's explanation i change my opinion.

For Q.12, Please let me know if it is [ sqrt(3) * sqrt (.0.000064) ] or [sqrt(cuberoot(0.000064))]

6. (E) $27,360 16. (E) 9y 12. © 0.02 6. (E) 68 13. (B) Four

IMO B Statement 1 : Doesn't say anything about the integer j. Statement 2 : 4 + j = 3h => j = 3h - 4 => for all values of h, j will not be a multiple of 9.

ANSWER : B 120 = 120 * 2 ^ (-a * 10) + 60 2 ^ (-a * 10) = 2 ^ (-1) 10a = 1 a = 1/10 F = 120 * 2 ^ (-30/10) +60 F = 75

I agree with 12rk34.

IMO 21/19 What is the OA?
