col b:(5^10)*(8^2)
Ans- B

2) Given that x*=(x-1)/x condition is x<0 x="x*..." x=" 9000/600" 99 =" 3^99" 33 =" 9^33" y="-5" y="5" 2y="5" 3y="-15" cube="X" cube="Xroot2" surface="Xroot2*X=" 2="main"> 0 & X>Y
Col A -------------------XZ
Col B-------------------YZ.
Sol: Case I: X=3, Y=2, Z=1 then col A is Greater.
Case II: X=5, Y= -2, Z= -3 then Col B is Greater
Therefore the answer is D

15). the mean of the three numbers 2X, 7X, X^2 (X square) is 12 what is the range of the given data (X<0). 3 =" 12" 2="36" 36="0" x=" -12" range =" Highest" commodity =" 144-" 3y="4" 4 =" 1" 3 =" 1" circle =" Pi" circle =" Pi" probability ="number" chance =" (X^2)">--------------------Number of people use only pagers
Col B ------------------------------------------------------- X – 12
Sol: Draw a Venn diagram Total number of people who watch television = 84.
No of people who watch TV and use pager = 84-X
Number of people who use only pager = 72- (84 – X) = 72- 84 + X = X- 12 Therefore C is the answer.

20). Find the Y – intercept of the equation 3X-2Y=5
Sol: X/ (5/3) + Y/ (-5/2) = 1,
Therefore the Y intercept is: -5/2

21). The amount of Rs.600/- is given at a rate of X% per annum , If he receives additional Rs.90/- after an year then what is the rate of interest ( i.e.- X )
Sol: For 600 rupees ------------------------90 rupees interest For 100 rupees-------------------------X X= 9000/600 = 15 rupees for 100 , which means 15%

options were...1) 3/8 2) 5/8 3)1/2
ans is 1/2

2) The average length of 5 frogs is 4.7m. another 5 frogs length are ( given some 5 no.'s here) like 4.5,5....( this questions is repeating many times rite from sep 3rd..So practice well)
cola....standard deviation of the lengths of 1st 5 frog’s
colb.....standard deviation of next 5 frogs.....

3) The near value of 10000 + sqrt (568.01+ 623.01)

Ans d

4) xyz=0 && x>y
col a.....xz
colb..... yz
and ans is D.
since if u take z=0 den ans is c and if u take y=0 (becoz x can’t be 0 as x>y) and x=1 and z=2..den ans is a..So dats y d final ans is d

5. The mean of the three numbers 2X, 7X, X^2 (X square) is 12 what is the range of the given data (X<0).>
Sol: (2X+7X+X^2)/3 = 129
X+X^2=36X^2+9X-36=0
By solving the roots are 3 and –12, but it is given that X<0 x=" -12">
Range = Highest commodity – lowest commodity= 144- (-84)= 228

6.) 2X+3Y=4 what is the X- intercept of the line
Sol: 2X/4 + 3Y/4 = 1
X/2 + Y/4/3 = 1
X- intercept is 2

7 .The Three vertices of a parallelogram is given as (0, 0) (1, 2) (3, 3) and asked to find out the fourth vertices. Sol: The answer is (2, 1), Figure is given and by that it is very easy to answer that question

8)There was a sum based on co-ordinate geometry-a parallelogram was given with one vertices at 0 and two more in +ve xy plane-we were asked to find the 4 the co-ordinate geometry was sort of vague
(5x+6/5x-6) =col a

9 A circle is drawn inside an other circle, the center of both circles are the same, the radius of the first circle is X and the radius of the second circle is X+Y, we are asked to find out the probability that if a point is taken from the circle the point should lie in the smaller circle of radius X.
Sol: Area of smaller circle = Pi (X^2)
Area of larger circle = Pi (X+Y) ^2
the probability = Number of favorable chance / Total number of chance= (X^2) / (X+Y) ^ 2

10. There are 84 people who watch television and 72 members use pagers and X members watch only Television.
Col A--------------------- Number of people uses only pagers
Col B----------------------X – 12
Sol: Draw a Venn diagram Total number of ppl who watch television = 84.
No of ppl who watch TV and use pager = 84-X
Number of ppl who use only pager = 72- (84 – X) = 72- 84 + X= X- 12
Therefore C is the answer.
