QUESTION: 16

Find the missing character.

Solution:
The lower number is obtained by adding the squares of the upper two numbers. Thus,

In fig. (A), 2^{2}+4^{2}=20.

In fig. (B), 3^{2}+9^{2}=90.

$\xe2\u02c6\xb4$In fig. (C), missing number = 1^{2}+5^{2}=26.

In fig. (A), 2

In fig. (B), 3

$\xe2\u02c6\xb4$In fig. (C), missing number = 1

QUESTION: 17

Solution:

QUESTION: 18

Find the missing character.

Solution:
Clearly, (1st cell of 1st column)^{2}+(2nd cell of 1st column)^{2}+(3rd cell of 1st column)^{2}=4th cell of 1st column.

Thus, in the first column, ${4}^{2}+{2}^{2}+{1}^{2}=21.$

In the second column, ${5}^{2}+{3}^{2}+{8}^{2}=98.$

$\xe2\u02c6\xb4$In the third column, missing number = ${6}^{2}+{7}^{2}+{3}^{2}=36+49+9=94.$

Thus, in the first column, ${4}^{2}+{2}^{2}+{1}^{2}=21.$

In the second column, ${5}^{2}+{3}^{2}+{8}^{2}=98.$

$\xe2\u02c6\xb4$In the third column, missing number = ${6}^{2}+{7}^{2}+{3}^{2}=36+49+9=94.$

QUESTION: 19

Find the missing character.

Solution:
Suppose X denotes the numbers in the first row and Y denotes the numbers in the second row.

Then, the pattern is X^{2} - X = Y.

3^{2} - 3 = 9 - 3 = 6; 8^{2} - 8 = 64 - 8 = 56; 10^{2} - 10 = 100 - 10 = 90;

2^{2} - 2 = 4 - 2 = 2; 1^{2} - 1 = 1 - 1 = 0.

Similarly, 5^{2} - 5 = 20.

So, the missing number is 5.

Then, the pattern is X

3

2

Similarly, 5

So, the missing number is 5.

Solution:
Clearly, 4 corresponds to C and a corresponds to 4. So, a corresponds to C.

1 corresponds to D and b corresponds to 1. So, b corresponds to D.

thus, CDCD corresponds to a, b, a, b.

1 corresponds to D and b corresponds to 1. So, b corresponds to D.

thus, CDCD corresponds to a, b, a, b.

A certain number of tennis balls were purchased for Rs 450.Five more balls could have been purchased for the same amounts if each ball was cheaper by Rs 15.Find the number of balls purchased.

Solution:

Let the number of balls purchased be x

Then, 450 x - 450 x + 5 = 15

⇒ 1 x - 1 x + 5 = 15 450

⇒ x + 5 - x x(x + 5) = 1 30

⇒ x^{2} + 5x - 150 = 0

⇒ (x + 15) (x - 10) = 0

x = 10

A park is in form of a rectangle 120 m x 100m. At the centre of the park is a circular lawn. The area of the park excluding the lawn is 10614 m^{2}. The cost of grass carpeting the lawn @ Rs. 27/m^{2} is

Solution:

Area of the park = 100 x 120

= 12000 m^{2}

Area of the park excluding the lawn = 10614 m^{2}

∴ The Area of the lawn = 12000 - 10614 = 1386 m^{2}

The Cost of fencing the lawn = Rs. (27 x 1386) = Rs. 37422.00

QUESTION: 106

A rectangular park is 200 by 150m. Two cross paths are to be made one parallel to the length and the other parallel to the breadth. The longer path is to be 3 m wide and the shorter is to be 2 m wide. The cost of grassing the remaining part of the park @ Rs. 1000 per ha is

Solution:

Area of the park minus the paths

= (200 - 3) (150 - 2)

= 197 x 147 sq. m

= 29156 sq. m

The cost of grashing the remaming part of the park = Rs 29156 10000 x 1000

= Rs 2915.6

The height of a wall is six times its width and the length of the wall is seven times its height. If volume of the wall be 16128 cu. m, its width is :

Solution:

Let us take width as x m

volume = 16128 cu m

⇒ (x) (6x) (42x) = 16128

x^{3} = 16128/ 42 x 6

x^{3} = 64

x = 4 m

QUESTION: 141

A solid metallic spherical ball of diameter 6 cm is melted and recast into a cone with diameter of the base as 12 cm. The height of the cone is :

Solution:

Diameter of the spherical ball, d = 6 cm

radius of the spherical ball, r = d 2 = 6 2 = 3 cm

Now, diameter of base of cone, D = 12 cm

Now, radius of base of cone, R = D 2 = 12 2 = 6 cm

Let the height of the cone = H

Now, spherical ball is melted and recast into the cone,

So, volume of cone = volume of spherical ball

⇒ 1 3 πR^{2}H = 4 3 πr^{3}

⇒ 1 /3 x 6 x 6 x H = 4 /3 x 3 x 3 x 3

⇒ 12H = 36

⇒ H = 3

So, height of the cone = 3 cm
