__Part-A__
1. 1) Find the area of the shaded
region in the given fig.

Solution:

Radius
of the circle = 2cm

Sides of the square =2√2

Area of the shaded region=(Area of the circle-Area of the square)/4

= (πr

^{2 }- a^{2})/4
= (4π - 8)/4

=
π-2

2. 2) The angles
of a
right angle triangular garden are in arithmetic progression. The smallest
side of the garden is 10m. Then Howmany
meters is needed to fence the garden ?

1) 10 2) 47 3) 60 4)

- From the following semicircle, AQ=2AP then
which of the following is correct?

1)
∟AQP=2∟APB

2)
∟AQB=∟APB

3)
∟AQB > ∟APB

4)
∟AQB < 2∟APB

- Two types
of rabbit community are A&B. Type A’s population is increasing 25% per
year. Type B’s population is increasing 50% per year. In the present year
both are equal. Then after two years
ratio of the population of B and A is ,

1)
1

2)
1.72

3)
1.94

4)
1.47

- From the
fig which of the following is correct?

1)
a + ab + ab

^{2 }+………..= a/(1-b), │b│<1
2)
a > b then a

^{3 }> b^{3}
3)
(a+b)

^{2 }= a^{2}+ 2ab + b^{2 }
4)
a > b then -a < -b
