Given rope of period = 40m (radius) 

Area of semi circle =(pi*r^2)/2 = (1600 * pi)/2 = 800*pi ---(1)

Area of sector circle = (1/2 * 800 * pi) = 400*pi ----- (2)

Area of area is = r*r*(pi/2)/2 = 25*pi ----- (3)

By including above eq. (1) (2) & (three)

Total area = 1225*pi

As per quesiton there are 2 goats

so area = 1225*pi*2 = 2450pi

Question thirteen. A Person Travels In A Car With Uniform Speed. He Observes The Milestone,which Has 2 Digits. After One Hour He Observes Another Milestone With Same Digits Reversed. After Another Hour He Observes Another Milestone With Same 2 Digits Separated By zero. Find The Speed Of The Car ?

Answer :

Let 10'splace digit is x and unit's region digit y

First milestone : 10x+y

Second milestone : 10y+x

Third milestone: 100x+y

Since the speed is uniform so

Distance covered in first Hr = Distance covered in Second Hr

(10y+x)-(10x+y) = (100x+y)-(10y+x)

By fixing,

y=6x 

however on account that x and y are digits so best feasible combination is x=1 and y=6,

So average velocity = forty five Kmph

Question 17. A Cylinder Is 6 Cms In Diameter And 6 Cms In Height. If Spheres Of The Same Size Are Made From The Material Obtained, What Is The Diameter Of Each Sphere ?

Answer :

The extent of the cylinder is Pi x r^2 x h = Pi x 3^2 x 6 = 54Pi 

Volume of a cylinder is 4/three x Pi x r^three 

Now 54Pi = 12 x 4/three x Pi x r^3 

54 = sixteen x r^3 

r^three = 54/16 = 27/eight 

r = three/2 

Therefore diameter is 3 cms

so total humans talk each = 4/5 + 4/7 - 9/10 = 33/70

persons talk any = 1 - 33/70 - 1/10 = three/7

% = 300/7% = forty two.86%

Question 21. Below Is A Pseudo Code Read X While(x < 60) Write X X = X*3

Answer :

The last number in the sequence is 54, what has the user entered as the initial value of x

Given Last value int seq. = 54.

And in every Loop result multiplied By 3.

So, The Starting Value Is 2

Question 22. If M^2+m^-2=23;then What Is The Value Of M^3+m^-three ?

Answer :

m^2+m^-2=23

=> (m + m^-1)^2 - 2 = 23

=> (m + m^-1) = 5

m^3+m^-3 = (m + m^-1)^3 - 3(m + m^-1) = 5^three - 3*five = a hundred and ten

Question 23. If M=2- _/3 Find The Value Of:

Answer :

(m^6+m^5+m^four+1)/m^three

m = (2 - ?3)

=> 1/m = (2 + ?3)

(m^6+m^five+m^4+1)/m^3

= m^three + m^2 + m + 1/m^3

= (m + 1/m)^three - three(m +1/m) + m(m+1)

= 4^three - three*4 + (2-?Three)(3-?Three)

= 64 - 12 + nine - 5?Three

= (61 - five?3)
