- 2m + n = 10, n = 5what is m
- if x, y positives and x/y < 1 then

hat he has given some questions. u can do it. But come from last question. Not from the first one՚s. They r very tough and r nothing but profit and loss, and averge, pecentge and so on. In analytical reasoning Two passages r given in that I can provide onlyone

Anlytic Ability of GRE BARRONS BOOK Of 13^{th} editon. The

English: COMMON TYPE OF ENGLISH CONTAINING ANALOGY, FINDING SOME WORDS FROM GOVEN TEXT ETC.

Logical reasoning

ALL FROM THE BOOK OF BARONS & Examrace Placement Series

Comparisons

10 power 11 − 10power 10 and 10 power 10

He ahs given a strigth line with points x z y on that such that compare xz and xy here we wiil think that xy is greater

He has given a triangle such that AB = BC = CA and he has drawn a straight line from A a⧵such that the line be AD now we have to compare BD and CD here we have say information is not sufficient since here he didn՚t give any information regarding that line. So we cant say whether it dives the segment BC into two equal halves

⚹ ⚹ ⚹ + + + This type of questions

Some squareroot problems he has given can՚t remember here the questions r very easy but see that they should be answered very carefully I think u got this. He hs given 20 questions ans u have to answer it in 5min # given circimference of a circle is 4pie and for other circle ihe has given the diameter. He asked to compare the radius of both circles.
