There are two circles of different radii. The area of a square is 196 sq.cm, whose side is half the radius of the larger circle. The radius of the smaller circle is three-seventh that of the larger circle. What is the circumference of the smaller circle?
A. 12π cm
B. 16π cm
C. 24π cm
D. 32π cm
Answer: C. 24π cm
Sol: Side of the square = √196 = 14 cm
Radius of the larger circle = 2 * 14 = 28 cm
Radius of the smaller circle = (3/7) * 28 = 12 cm
Circumference of the smaller circle = 2π * 12 = 24π cm
The perimeter of a square is equal to the perimeter of a rectangle of length 16 cm and breadth 14 cm. Find the circumference of a semicircle whose diameter is equal to the side of the square. (Round off your answer to two decimal places).
A. 23.57 cm
B. 47.14 cm
C. 84.92 cm
D. 94.94 cm
Answer: A. 23.57 cm
Solution:
Perimeter of the rectangle = 2(16 + 14) = 60 cm
Perimeter of the square = 60 cm
Side of the square = 60 / 4 = 15 cm
Diameter of the semicircle = 15 cm
Circumference of the semicircle = (1/2)π * 15 + 15 = (1/2)(22/7) * 15 = 23.57 cm
A 25 cm wide path is to be made around a circular garden having a diameter of 4 meters. Approximate area of the path in square meters is:
A. 3.34
B. 2
C. 4.5
D. 5.5
Answer: A. 3.34
Solution:
Radius of the inner circle = 4/2 = 2 meters
Radius of the outer circle = 2 + 0.25 = 2.25 meters
Area of the path = π(2.25² – 2²) = π(5.0625 – 4) = π(1.0625) = 3.34 sq meters
A cuboidal block of 6 cm X 9 cm X 12 cm is cut up into an exact number of equal cubes. The least possible number of cubes will be:
A. 6
B. 9
C. 24
D. 30
Answer: C. 24
Solution:
Volume of the block = 6 * 9 * 12 = 648 cm³
Side of the largest cube = H.C.F. of 6, 9, and 12 = 3 cm
Volume of one cube = 3³ = 27 cm³
Number of cubes = 648 / 27 = 24
I. 9a2 + 18a + 5 = 0,
II. 2b2 + 13b + 20 = 0 to solve both the equations to find the values of a and b?
A. If a > b
B. If a ≥ b
C. If a < b
D. If a ≤ b
Ans: A. If a > b
Explanation:
I. 9a2 + 3a + 15a + 5 = 0
=>(3a + 5)(3a + 1) = 0 => a = -5/3, -1/3
II. 2b2 + 8b + 5b + 20 = 0
=>(2b + 5)(b + 4) = 0 => b = -5/2, -4
a is always more than b.
a > b.
I. x2 + 9x + 20 = 0,
II. y2 + 5y + 6 = 0 to solve both the equations to find the values of x and y?
A. If x < y
B. If x > y
C. If x ≤ y
D. If x ≥ y
Ans: A. If x < y
I. x2 + 4x + 5x + 20 = 0
=>(x + 4)(x + 5) = 0 => x = -4, -5
II. y2 + 3y + 2y + 6 = 0
=>(y + 3)(y + 2) = 0 => y = -3, -2
= x < y.
9000 + 16 2/3 % of ? = 10500
A. 1500
B. 1750
C. 9000
D. 7500
Ans: C. 9000
Explanation:
9000 + 16 2/3 % of ? = 10500 => 9000 + 50/3 % of ? = 10500
50/(3 * 100) of ? = 1500 => ? = 1500 * 6
? = 9000
Two pipes A and B can fill a cistern in 37 1/2 minutes and 45 minutes respectively. Both pipes are opened. The cistern will be filled in just half an hour, if the pipe B is turned off after?
A. 5 min
B. 9 min
C. 10 min
D. 15 min
Ans: B. 9 min
Explanation:
Let B be turned off after x minutes. Then, part filled by (A + B) in x min + part filled by A in (30 – x) min = 1.
x(2/75 + 1/45) + (30- x) 2/75 = 1
11x + 180 – 6x = 225 => x = 9
Two pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 3 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. The capacity of the tank is?
A. 60 gallons
B. 100 gallons
C. 120 gallons
D. 180 gallons
Ans: C. 120 gallons
Explanation:
Work done by the waste pipe in 1 minute = 1/15 – (1/20 + 1/24) = – 1/40
Volume of 1/40 part = 3 gallons\
Volume of whole = 3 * 40 = 120 gallons.
I. a3 – 988 = 343,

D. If a ≤ b
Ans: B. If a ≥ b
Explanation:
a3 = 1331 => a = 11
b2 = 121 => b = ± 11
a ≥ b
