A tank is filled 10% in 1hour and 8% of the water is emptied in the next hour. If it is repeated again, find the percentage of tank filled with water

Answer» The TANK will be FILLED 10% in the FIRST hour. In next hour 8 % of it = 10 * 8/100 = 8 % of the tank is emptied. Remaining water after the second hour is 9.2%. Again in the THIRD hour, 10% tank is filled, it BECOMES 19.2%. Again, 8% of it i.e. 19.2 * *8/100 = 1.536 % is emptied in the fourth hour , So remaining water is 19.2 – 1.536 = 17.66 %

As usual, draw a diagram.
Your will see that the distances to top and BOTTOM of TOWER are 

top/55 = tan 60° 
bottom/55 = tan 45° 

Now just EVALUATE top and bottom, and you can SUBTRACT to get the height of the tower. 

You should get 55(√3 - 1)

Let Akbar and Birbal together have 'n' marbles, n>o.Akbar says to Birbal,"If I give you some marbles then you will have twice as many marbles as I will have."Birbal says to Akbar,"If I give you some marbles then you will have thrice as many marbles as I will have."What is the minimum possible value for 'n' for which the above statements are true?

Answer»

Final Answer:12

Step 1 :
Let Akbar and Birbal have 'a' and 'b' no. of Marbles.
Then,
according to the Question,
a + b = n ------------(1)

Step2:
Now,
Akbar gave 'x'(say) marbles to Birbal.
Then,
2(a-x) =(b+x)
=> 2a-b=3x ---------(2)

Step3:
Then,
Birbal gave 'y'(say) marbles to Akbar.
(a+y) = 3(b-y)
=>3b-a=4y------(3)

We have,
EQ. (2) and(3) ,
Finding a and b from both these EQUATIONS in terms of x and y.
we get,
a= (9x+4y)/5
b= (3x+8y)/5 .

Substituting value of a and b in equation 1.

a+b= n
=> n = 12(x+y)/5.

For 'n'to be the SMALLEST natural number.
x+y=5:
=> n = 12
----------------------------
Therefore, smallest value of n is 12.

The perimeter of a rectangle is 100 cm and its length is 30 cm . what is the breadth of the rectangle ? what is the area of the rectangle?

Answer»

Perimeter of rectangle = 2(length + BREADTH)
----------------------------------

100= 2(30+ breadth)

100/2 = 30+ breadth

50=30 + breadth

50-30= breadth

20cm = breadth


-----------------------------------

Then,

Area of rectangle =length×breadth

Area of rectangle = 30×20

Area of rectangle = 600 cm²

Solution for q5. ans is [(x-3)^2 - 1]

Answer»

The answer is given below :

Given that,

f(X + 3) = x² - 1

To FIND f(x), we replace x by (x - 3).

Then, we get

f(x - 3 + 3) = (x - 3)² - 1

⇒ f(x) = x² - 6x + 9 - 1,
using the identity (a - B)² = a² - 2ab + b²

⇒ f(x) = x² - 6x + 8

Thus, f(x) = x² - 6x + 8

Thank you for your question.
