60/1200*900 = 45

90/1000*900 =81

so, 45+81/2 = 126/2 = 61 ans.

Hi All,

Correct me if m wrong !

(a,b,c,d) would represent a cyclic rectangle so a+c = b+d = 180

tan A = tan(180-C) = -tan C

similarly tan B = tan(180-D) = -tan D

hence tan A + tan B + tan C = 5

-tan C -tan D + tan C = 5
tan D = -5

Rajend

solution:-
A+C=180 and B+D=180
so tan(A+C)=tan180
  it means tanA+tanC=0
similarly tanB+tanD=0

so tanA+tanB+tanC+tanD=0
5+tanD=0
tanD=-5

am i wrong???if i am...then please correct me....

Hi

Here is this week's CAT Prep question. This is a data sufficiency question in Geometry. Tests your basic understanding of Circles.

Question

Does the circle A with radius ‘a’ touch circle B with radius ‘b’ internally?

A. The two circles touch each other at only 1 point
B. The distance between centers of A and B is a-b

Correct answer and explanation @ http://iim-cat- forum.2iim. com/about98. html

well it is being partly constant so suppose that

x is varying and y is constant

so the eqn will be

60x+y=1200*60

90x+y=1000*90

solve it

u will get answer

rem the constant part cant be changed

x+y/60=1200
x+y/90=1000

solving these two equations,y= 36000 ==>x=600
using this value,600+36000/ n=900
n=120.

Let me know if this is correct.

           In the above problem for an increment of 30 people there is an decrase
in amount of 200 rupees.So for an decrement of 100 rupees we've to have an
increment of 15 people.Dat makes the total as 15+90=105.

Hi,
the answer to the asked question would be -5,
bcoz the quad. is a cyclic one and so the sum of opposite angles would be 180
deg. tan(A+C)=(tan A + tan C)/(1- tanA.tanC).suppose  A and C are the opposite
angles. Therefore ,tan A +tan C=0.
After manipulating in the given eqn.  we would get the ans. of
tan D =-5

So total 40 number will be eliminated from sequence and 1041 is the 1000th term.

You are absolutely right. 64 is both square and cube hence 1 will be excluded
from list (of vinayak's 41).

apparently the 1000th term becomes 1040. But since 1024 is a square and it ll
not be a part of series, the final 1000th term becomes 1041.

So D is correct!

The Answer should be 1038 , because there are 30 squares ( from 2 to 31) and 9 cubes(from 2 to 10 ) and two are eliminated( 64 and 729) .So in total there are 37( 30+9 -2) nos including cubes and squares .

And the series is starting from 2 , therefore 1000th term is 1000 + 37 + 1 = 1038

Hi, The answer is D, Because there are 31 square numbers(1 4 9 16 25 36 49 64 81 100 121 144 169 196 225 256 289 324 361 400 441 484 529 576 625 676 729 784 841 900 961) & 9 Cube numbers(8 27 64 125 216 343 512 729 1000). So total 40 number will be eliminated from sequence and 1041 is the 1000th term.

A number subtracted by sum of its digits will always be a multiple of 9. For example take 3 digits - x, y, z.

The number is 100x + 10y + z

Number subtracted by sum of digits = (100x + 10y + z) - (x+y+z) = 99x+9y (always a multiple of 9)

The sum of digits available is 46. For the number to be divisble by 9, the sum of digits has to be divisble by 9. Hence 8 is the missing digit.

The answer is 6.

Explaination - Take 2 adjacent exterior circles & the inner circle. Join their centres. You will get an equilateral triangle of each edge 2r. Angle created by 2 circles is 60 so 6 such circles are possible.
