A. 42%
B. 62%
C. 82%
D. none of these

If the ratio of the areas of two squares is 9:1 ratio of their perimeters is_________?
A. 9:1
B. 3:1
C. 3:4
D. 1:3
The area of a rectangle is thrice that of a square. The length of the rectangle is 40 cm and the breadth of the rectangle is (3/2) times of the square. The side of the square in cm is__________?
The area of a rectangle is thrice that of a square. The length of the rectangle is 40 cm and the breadth of the rectangle is (3/2) times of the square. The side of the square in cm is__________?
A. 15
B. 20
C. 30
D. 60
The length of a hall is (4/3) times its breadth. If the area of the hall be 300 square meters the difference between the length and breadth is__________?
The length of a hall is (4/3) times its breadth. If the area of the hall be 300 square meters the difference between the length and breadth is__________?
A. 15m
B. 4m
C. 3m
D. None of these
Explanation:
Breadth = x meters
Length = ( 4/3 x) m
X × 4/3 x = 300 or x2 = 300 × 3/4 = 225 or x =15
Hence, [(Length) – (breadth)] = ( 4/3 x-x) = 1/3
x => ( 1/3×15) m = 5 m
If the side of a square is increased by 25 % then how much percent does it’s area get increased:
If the side of a square is increased by 25 % then how much percent does it’s area get increased:
A. 125
B. 156.25
C. 50
D. 56.25
The ratio between the length and breadth of a rectangular field is 5:4. If the breadth is 20 meters less than the length. The perimeter of the field is_________?
The ratio between the length and breadth of a rectangular field is 5:4. If the breadth is 20 meters less than the length. The perimeter of the field is_________?
A. 260m
B. 280m
C. 360m
D. None of these
Explanation:
5x – 4x = 20 or x = 20
Length = (5 x 20) m = 100 m
Breadth = (4 x 20) = 80 m
Perimeter = 2(100+80) = 360 m
The length and breadth of a rectangular piece of land are in the ratio of 5:3. The owner spent Rs 3000 for surroundings it from are the sides at Rs 7.50 per meter. The difference between is length and breadth is_________?
The length and breadth of a rectangular piece of land are in the ratio of 5:3. The owner spent Rs 3000 for surroundings it from are the sides at Rs 7.50 per meter. The difference between is length and breadth is_________?
A. 50m
B. 100m
C. 150m
D. 200m
Explanation:
Let length = 5x meters and breadth = 3x meters
Perimeter = 2 x (5x + 3x) m = 16x metres.
Perimeter = Total cost/Rate = (3000/7.50) m = 400 m.
16x = 400 or x = 25
(Length) – (breadth) = (5 x 25 – 3 x 25)m
= (2 x 25) = 50 m
The length and breadth of play ground are 36 m and 21 m respectively. Flag staffs are required to be fixed on all along the boundary at a distance of 3 m part. The number of flag staffs will be___________?
The length and breadth of play ground are 36 m and 21 m respectively. Flag staffs are required to be fixed on all along the boundary at a distance of 3 m part. The number of flag staffs will be___________?
A. 37
B. 38
C. 39
D. 40
Explanation:
Perimeter = 2×(36+21) m = 114 m
Number of flag staffs = (114/3) = 38
