Is it not the same. What is the answer?

"multiple of 2 and 8 " so the number should be divisible by both 2 and 8. If the number is multiple of 8 it surely will be multiple of 2 so we only need to find the numbers multiple of 8. Now how frequently multiple of 8 occur. 1, 2, 3, 4, 5, 6, 7,8, 9, 10, 11, 12, 13, 14, 15, 16 it occur every eight number so the probability that it is a multiple of 8 is 1/8

No repetation. 6! is the ans when u arrenge six nubers in six place, we have a extra fixed position so i get confused and thought the ans shold be different. Now its clear :)

Dear Farzana from which test did u got this ques? (I don't even understand the ques) (I mean Test 1 or 2?)

got u now. thanks.

Thanks Zephyr your explanation is nice, ans is 720 Can u explain why u do this rohitanna?

a. A prime (Let p is a prime, so it has divisors 1, p ... number of different divisors greater than 1 is one namely p) b. An even integer (say 8, it has divisors 1, 2, 4, 8 ... number of different divisors greater than 1 is 3) c. A multiple of 3 (say 3, it has divisors 1, 3 ... number of different divisors greater than 1 is 1) d. the square of a prime(say p is a prime so p^2 has divisors 1, p, p^2 ... number of different divisors greater than 1 is two p and p^2 ) e. the square of an odd integer ( say 15^2, it has divisors 1, 3, 5, 9, 15, 25 ...and more way more than two different divisors greater than 1) Attachment ans.

7 possitions. sorry i forget to give that. ans choise are: 1. ? 2. ? 3. 120 4. 340/360/382 (i cann't remember exactly lets say 3?) 5. 720

3. A positive integer with exactly 2 different divisors greater tahn 1 must be (ref: test -10 ques: 29 page:401) a. A prime b. An even integer c. A multiple of 3 d. the square of a prime e. the square of an odd integer ans. e. the square of a prime has three divisors(1,p,p^2) ques says greater than 1 so p and p^2

I didn't get the question?

how many numbers are there if keep 4 in 4'th position 1, 2, 3, 4, 5, 6, 7 ?

but your count do not consider when one of them is blue.

My ans is 27/28 which is not on the list !!!!!!!

like this sol. time saving.

well, pp gre/toefl has a ques bank inside. so if u give the exams more than two time u will see new ques with couple of old one. as this test is adaptive, u may not see all the ques no matter how many times u give the test. in pp toefl there are Listening test 1 210 ques test 2 206 ques Reading(25 rc for each test) test 1 275 ques test 2 275 ques Structure test 1 143 ques test 2 143 ques Yea, you can straight away use Powerprep which is easily available but u may not see all ques pp got. i ask, if somebody have all/ almost all the ques please share. thank u.

3. S= {1,2,3 .. 48} 48/2 = 24 number each odd/even group v = { 2, 4, 6, ..., 48} D = { 1, 3, 5, ..., 47} ----------------------- .... 1 + 1 + 1+...+1 =24 As you see V = D + 24 4. The boundery is 100 m long so for circle its the circumference and for square its the perimeter. col A --------------- 2*pi*r = 100 r = 50/pi Area of circle = pi * (50/pi)^2 = (50 * 50)/pi = 25 * 25 * 4/pi col B --------------- 4x = 100 x = 25 Area of square = 25 * 25 Clearly 4/pi is greater than 1 so Col A greater

1. Let they will meet after x hour train T left the station. by that time train T pass 60x miles and train S pass 75(x-2) mile. s0, 60x = 75(x-2) 60x = 75x - 150 15x = 150 x =10 Add 9:00 am + 10 hour = 7:00 pm 2. A = 7% of sol - I = 7% of 3 = 0.21 A = 14.5% of sol - II = 14.5% of 2 = 0.29 A = (0.21+0.29)/5 * 100% = 0.5/5 * 100% = 10%

Same as above, but .. 2^n * K = 12^10 .........= (3 * 4)^ 10 .........= (3 * 2^2)^10 .........= (3^10 * 2^20) 2^n is factor of 12^10, so the highest possible value for n is 20.

yep. missed this line "if the sequence was a ap/gp then". thanks.

5.) Column A : sqrt(79x80x81x82) Column B :6400 col B: sqrt(80 x 80 x 80 x 80) consider for smaller case: 2 x 3 x 4 x 5 = 120 3 x 3 x 3 x 3 = 81 so, col A is greater. please search previous posts for ques 1-4.

thanks. i took 3.5, 3.5, 4 and 4, 4, 3 missed 3 3 4

from first post 2) cp,cq,cr,cs,ct,cu is also anAP...provided c>=1 from second post 3)cp,cq,cr,cs,ct is a gp.. no matter whether c1 my ques is when c>1 is it AP or GP ?

thanks. wait. (0, 2x) was a typing error. i mean (0, x), as u asumed. how do say both intercept has the same sign. it just say double. can u please clarify that?
