Subsequently, the dimensions of the carpet were altered such that its length and breadth were in the ratio 7 : 3 but were was no change in its parameter. Find the ratio of the areas of the carpets in both the cases.

(a) 4 : 3

(b) 8 : 7

(c) 4 : 1

(d) 6 : 5

Ans: (b) 8 : 7

Sol: Let the length and breadth of the carpet in the first case be 3x units and 2x units respectively.

Let the dimensions of the carpet in the second case be 7y, 3y units respectively.

From the data,.

2(3x + 2x) = 2(7y + 3y)

=> 5x = 10y

=> x = 2y

Required ratio of the areas of the carpet in both the cases

= 3x * 2x : 7y : 3y

= 6×2 : 21y2

= 6 * (2y)2 : 21y2

= 6 * 4y2 : 21y2

= 8 : 7 - The sector of a circle has radius of 21 cm and central angle 135o. Find its perimeter?

(a) 91.5 cm

(b) 93.5 cm

(c) 94.5 cm

(d) 92.5 cm

Ans: 91.5 cm

Sol: Perimeter of the sector = length of the arc + 2(radius)

= (135/360 * 2 * 22/7 * 21) + 2(21)

= 49.5 + 42 = 91.5 cm - The length of a rectangle is two – fifths of the radius of a circle. The radius of the circle is equal to the side of the square, whose area is 1225 sq.units. What is the area (in sq.units) of the rectangle if the rectangle if the breadth is 10 units?

(a) 140

(b) 156

(c) 175

(d) 214

Ans: 140 sq.units

Given that the area of the square = 1225 sq.units

=> Side of square = √1225 = 35 units

The radius of the circle = side of the square = 35 units Length of the rectangle = 2/5 * 35 = 14 units

Given that breadth = 10 units

Area of the rectangle = lb = 14 * 10 = 140 sq.units - The ratio of the volumes of two cubes is 729 : 1331. What is the ratio of their total surface areas?

(a) 81 : 121

(b) 9 : 11

(c) 729 : 1331

(d) 27 : 12

Ans: (a) 81 : 121

Sol: Ratio of the sides = ³√729 : ³√1331 = 9 : 11

Ratio of surface areas = 92 : 112 = 81 : 121 - The volumes of two cones are in the ratio 1 : 10 and the radii of the cones are in the ratio of 1 : 2. What is the length of the wire?

(a) 2 : 5

(b) 1 : 5

(c) 3 : 5

(d) 4 : 5

Ans: 2 : 5

Sol: The volume of the cone = (1/3)πr2h

Only radius (r) and height (h) are varying.

Hence, (1/3)π may be ignored.

V1/V2 = r12h1/r22h2 => 1/10 = (1)2h1/(2)2h2

=> h1/h2 = 2/5

i.e. h1 : h2 = 2 : 5 - The radius of a wheel is 22.4 cm. What is the distance covered by the wheel in making 500 resolutions.

(a) 252 m

(b) 704 m

(c) 352 m

(d) 808 m

Ans: (b) 704 m

Sol: In one resolution, the distance covered by the wheel is its own circumference. Distance covered in 500 resolutions.

= 500 * 2 * 22/7 * 22.4 = 70400 cm = 704 m - The dimensions of a room are 25 feet * 15 feet * 12 feet. What is the cost of white washing the four walls of the room at Rs. 5 per square feet if there is one door of dimensions 6 feet * 3 feet and three windows of dimensions 4 feet * 3 feet each?

(a) Rs. 4800

(b) Rs. 3600

(c) Rs. 3560

(d) Rs. 4530

Ans: (d) Rs. 4530

Sol: Area of the four walls = 2h(l + (b)

Since there are doors and windows, area of the walls = 2 * 12 (15 + 25) – (6 * 3) – 3(4 * 3) = 906 sq.ft.

Total cost = 906 * 5 = Rs. 4530 - A cube of side one meter length is cut into small cubes of side 10 cm each. How many such small cubes can be obtained?

(a) 10

(b) 100

(c) 1000

(d) 10000

Ans: (c) 1000

Sol: Along one edge, the number of small cubes that can be cut

= 100/10 = 10

Along each edge 10 cubes can be cut. (Along length, breadth and height). Total number of small cubes that can be cut = 10 * 10 * 10 = 1000 - The length of a rectangular floor is more than its breadth by 200%. If Rs. 324 is required to paint the floor at the rate of Rs. 3 per sq m, then what would be the length of the floor?

(a) 27 m

(b) 24 m

(c) 18 m

(d) 21 m

Ans: (c) 18 m

Sol: Let the length and the breadth of the floor be l m and b m respectively.

l = b + 200% of b = l + 2b = 3b

Area of the floor = 324/3 = 108 sq m

l b = 108 i.e., l * l/3 = 108

l2 = 324 => l = 18. - The ratio of the length and the breadth of a rectangle is 4 : 3 and the area of the rectangle is 6912 sq cm. Find the ratio of the breadth and the area of the rectangle?

(a) 1 : 96

(b) 1 : 48

(c) 1 : 84

(d) 1 : 68

Ans: (a) 1 : 96

Sol: Let the length and the breadth of the rectangle be 4x cm and 3x respectively.

(4x)(3x) = 6912

12×2 = 6912

x2 = 576 = 4 * 144 = 22 * 122 (x > 0)

=> x = 2 * 12 = 24

Ratio of the breadth and the areas = 3x : 12×2 = 1 : 4x = 1: 96. - What is a Kerr black hole?
