1.there are 4 exactly Sunday and 4 Thursday in the month of 31
days.so find the 1st day of tht month.
2.sum of 2 no is 50 and sum of there reciprocal is 1/12. So find
these number.
3 there was 1 Q based on critical reasoning.
4. I had 6 -7 Q on time and work,time and distance, probability,
ages. But don’t remember it nw.
5. I don’t remember the exact value. But the Q was-
Wht should be added in 6440 that is when divided by
460 gives reminder 35.
7.Arun was all bent on building a new house. He carefully got the
blue print of his house designed buy his friend Ashwin, a civil engineer. He
wanted to build a room of dimension 27 by 48 ft and lay tiles in this room.
Each tile was of dimension 2 by 3 ft. How many tiles should Arun buy?

8.Father is aged three times more than his son Ronit. After 8
years, he would be two and a half times of Ronit’s age. After further 8 years,
how many times would he be of Ronit’s age? a.2 b.5/2 c.3/2 d.1
Ans A)2 times.
Given F=3S+S=4S —-(1)
F+8=5/2(S+8)—-(2)
By Substituting F=4S in (2) We get S=8
Therefore F=32.
Since After 16 years,F=48,S=24
So Father’s age after 16 years is 2 times of Son’s age.
9.Roy is now 4 year older than Erik and half of that amount than
Lewis.If in two years Roy will be twice as old as Erick,then in two year what
would be Roy age multiplied by Lewis age??
ans is 48
firstly two equation from 1st sentence ..
suppose roy=x, erik=y, lewis=z
so x=y+4….(1)
2nd is x=z+2…(2) (Roy is now 4 year older than Erik and half of
that amount than Lewis so 4/2=2)
also after 2 years erik and roy relation wil b
x+2=2(y+2).. (3)
so put this into 1st equ. u will get y=2..
and then x=6,z=4(by substituting other)
nw asking multiplication after two years of roy n lewis is
(6+2)*(4+2)=48..
10.If there are maximum acute angles then how many convex
hectagons are there?
11.if a divided by 5,3,2 respectively give the remainder
1,2,0.what is the no when is divided by 2 3, 5
number
12.How many polygon function of degree less than equal to 1
satisfy f(x)^2={f(n)^2={f{f(x))
13.The number of bacteria was growing in a city exponentially.at 4
pm yesterday , the number of bacteria was 400 and at 6 pm yesterday it was
3600.How many bacteria were there at 7pm yesterday?
10800
14.maximun number of identical pieces(of same size) of a cake by
making only 3 cuts? -6
15.Find the area (in square units) of the triangle formed by
2x+3y=5, y=x and X-Axis.
the points of intersection for lines:
2x+3y=5 and x=y => 5x=5 => x=1 and y=1 =>(1,1)
x=y and y=0(x-axis) => x=0 and y=0 =>(0,0)
2x+3y=5 and y=0(x-axis) => 2x=5 => x=5/2 and y=0
=>(5/2,0)
area of triangle with vertices (x1,y1),(x2,y2),(x3,y3) is
|x1(y2-y3)+x2(y3-y1)+x3(y1-y2)|/2
=|1(0-0)+0(0-1)+5/2(1-0)|/2
=|1+5/2|/2
=7/4 sq units…
16.The ratio of perimeter of an equilateral triangle having an
altitude equal to the radius of the circle, to the perimeter of an equilateral
triangle inscribed in that circle is ?
17.35674 term in 1 ,2,3,4,5,6,7,8,9,10,11,12,13….
35674
