Hi puys,

Two circles C(O,r) and C(O',r') intersect at two points A and B. A tangent CD is drawn to the circle C(O',r') at A. then

1) /_OAC=/_OAB 2) /_OAB=/_AO'O
3) /_AO'B=/_AOB 3) /_OAC=/_OAB

the question is from LOD2(Geometry) Arun Sharma Qno. 21.

bro ,now i will solve ur problem.......................

the question is that--->
in 1995,5% population increases..............
in 1996,5% population increases..............
in 1997,5% population increases..............
in 1998,5% population increases..............
but in in 1999,20% population decreases..............
and in 2000,10% increases ......................

suppose population is x in 2001..................so ,in 2000 it will be 10x/11(due to 10% increase )
now in 1999,it will be (10x/11)*(5/4)
now,prior year it was 5% increment...............so ,from 1999 to 1995 ............there was only 4 years
so.........it will be.................
original population in 1995,
---->(10x/11)*(5/4)*((20^4)/(21^4))

calculate u will get option B............

Actually when i read the question i feel that its not clearly mentioned dat the %change in yrs 96 - 98 is 5%.

"the growth rate of the population was 10% last year and 5 % the year prior to it, the only exception being 1999 "

Can you help me understand if i m wrong.
(it wud not have been confusing for me if:
"the growth rate of the population was 10% last year and 5 % the years prior to it, the only exception being 1999 "
).

The population of Mangalore was 1283575 on 1st jan 2001 and the growth rate of the population was 10% last year and 5 % the year prior to it, the only exception being 1999 when because of the huge exodus there was a decline of 20% in population. what was the population on 1st jan 1995?
a) 1000,000
b) 1200,000
c) 1250,000
d) 1500,000
e) None of these

One more in which i hv a dbt(wat will be the population growth rates for the yrs 98,97,96)? (my initial attempt i thought it to be a increasing AP that is : 0.625%,1.25% and 2.5 % for 96,97 and 98

Mr. X a very industrious person, wants to establish his own unit. For this he needs an instant loan of Rs. 500,000 and, every 5 yrs he requires an additional loan of Rs. 100,000. If he had to clear all his outstandings in 20yrs, and he repays the principal of the first loan equally over 20 yrs, find what amount he would have to pay as interest on his initial borrowing if the rate of interest is 10% p.a SI.
a) 560,000 b) 540,000
c) 525,000 d) 500,000
e) None of these

puys please help me solving this qstn.(the dbt i have here is how do we need to consider the additional 100000 that he takes every 5 yrs)

###### CATQuant by Arun Sharma
Simple Interest=original amount*rate*time/100
CI=original amount*(1+rate/100)^time

is correct answer for 2nd is -----a)20 ??

For the second 1 if u take the principal as 100 and interest rateas 10 . u can see that u will have CI = 10 + 11 for 2 yrs.(which is wat given in the question)

while SI on a principal of 100 for 10% interest for 2 yrs will be 10 + 10 = 20.
Also difference between SI and CI for 2 yrs is p*(r/100)^2

1. If the timing and reasoning behind Sothebys decision to go ahead are obvious, the reasons Mr.
Hirst wants to risk his reputation for a one-off fire sale are more subtle.
B. Although he has benefited from the contacts and clout that his dealers provide, he is irked by their
habit of making potential new buyers prove themselves by waiting before they are allowed to
purchase a work of art.
C Anyone with enough money can buy what they want immediately.
D. Much of it has to do with his natural impatience, his wish to break rules and break down boundaries.
E. Dealers are gatekeepers who permit artists access to serious collectors, explains Mr. Thompson.
Auction rooms, by contrast, are more democratic.

a.BDEC b.BDCE c.DEBC d.DBEC

My take is also D.

My take is 3.
the opinion of scientists is already mentioned in the passage. So the logical link is the conclusion that they are trying to derive.

One from my side:

Q. Which of the following best completes the passage below?
the most serious flaw in televisions coverage of election campaigns is its tendency to focus on the horse-race side of politicsthat is, to concentrate on the question Whos winning? at the expense of substantive coverage of the issues and the candidates positions on them. The endless interviews with campaign managers, discussions of campaign strategies, and, especially, the obsession with opinion polls have surrounded elections with the atmosphere of a football game or a prizefight. To reform this situation, a first step might well be______
(A) a shortening of the length of election campaigns to a period of six weeks
(B) a stringent limit on campaign spending
(C) a reduction in the television coverage of opinion polls during election campaigns
(D) the publication and distribution of voter-education literature to inform the public about each candidates position on the major issues.

My take on it will be D. The underlined portion is a link for it.
