My pick is also D......but OA is E...........this is from NOVA.........

APOCRYPHAL : CORROBORATION :: (A) didactic : instruction (B) fraudulent : forgery © tyrannical : poise (D) esoteric : commonality (E) sacrilegious : piety

u can select the univ and the department from the pop down menu.......all u need to know the district in which univ is situated and exact name of univ(u can see some univ with same name but location different in same district).....

There wont be anything on screen except questions, timer and some control buttons......u'll be given paper and pencil for rough works........... suggest u to take a powerprep before starting practise.......the real test is exact replica of this........

Let the 5 digit no: be ABCDE this can be written as A*10000+B*1000+c*100+D*10+E the reflection of original no: is EDCBA this can be written as E*10000+D*1000+c*100+B*10+A so difference ==>ABCDE - EDCBA = (A*10000+B*1000+c*100+D*10+E) - (E*10000+D*1000+c*100+B*10+A) = A*9999+B*990+C*0-D*990-E*9999 so each term in difference is divisible by 9. Square both colums A: 79*80*81*82 B:80*80*80*80 so by comaping we can easily say A>B HTH

An+1 = (An - 3)^2 A1=4 A2=1 A3=4 A4=1 A5=4 so this series is having odd no: = 4 and even no:=1 So ans 4

mean hrs= 140/7 = 20 h,h,h,h,2h,2h,2h so h is the median also h+h+h+h+2h+2h+2h=140 ==> h=14 so difference=6 HTH

Cant tell.........just depends on ur luck.........i got all my words from Barrons HF only.......... many of my friends got out of barrons.......

1.IMO B no integers' square end in 2. 5. 22/7 is pi =3.14 or can be taken as 21/7(app) and 7/22=1/3 (app) 3.14 - .33= 2.81 (app) so ans D

The purpose of giving food is to make them friendly not to make them hostile.....i think u missed the key word "less"

S=n/2[2 + n-1]=n(n+1)/2 ------> sum of n terms of AP with a1=1 and d=1 S1=n/2[4 + (n-1)*2]= n(n+1) = 2S ------->sum of n terms of AP with a1=2 and d=2 HTH

with ur reasoning........D also fits ur bridge........enlist is voluntary while conscript is forced........

IMO C Y is the payment(money paid) for X

Ten fold change means for every 10 degree change in magnitude the intensity multiplies by 10. ie from 125 to 165, increase in magnitude is 40 so for total 4 ten degree change in magnitude corresponding change in intensity is 10*10*10*10
