What is the perimeter of a semi-circle lake having a radius of 700m? (CSS-2024)
A. 127.4 km
B. 3.6 km
C. 2.9 km
D. None of these
Discuss
Save
Correct Option
Explanation
Perimeter = πr + 2r = 700π + 1400 ≈ 2200 + 1400 = 3600 m = 3.6 km. Option C (2.9 km) seems incorrect; likely a typo.
63
Name the regular polygon that has an exterior angle of 36. (CSS-2024)
A. Pentagon
B. Hexagon
C. Decagon
D. None of these
Discuss
Save
Correct Option
Explanation
Exterior angle = 360/n. Then 360/n = 36, n = 10 (decagon).
64
Find the value of a, when A = (2x + y)x^2, where A = 36 and y = 2.77. (CSS-2024)
A. 3
B. 4
C. 2
D. None of these
Discuss
Save
Correct Option
Explanation
A = x^2(2x + 2.77) = 36. Let z = x^2. Then z(2√z + 2.77) = 36. Solve numerically or test options; x = 2 fits approximately.
65
Find the value of a^3 + 2b^2, when a + b = 5 and ab = 6. (CSS-2024)
A. 37
B. a = 3, b = 2 (or vice versa). Then a^3 + 2b^2 = 27 + 2×4 = 35. Option A (37) seems incorrect;
C. 13
D. None of these
Discuss
Save
Correct Option
Explanation
a + b = 5, ab = 6. Then a^2 + b^2 = (a + b)^2 - 2ab = 25 - 12 = 13. a^3 = a(a^2 + b^2 - b^2) = a(13 - b^2). Use (a - b)^2 = (a + b)^2 - 4ab = 25 - 24 = 1, so a - b = ±1. Solve for a,
66
What integer values can n have, given the inequality, -7 < 4n ≤ 8? (CSS-2024)
A. -1, 0, 1, 2
B. -2, -1, 0, 1, 2
C. -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8
D. None of these
Discuss
Save
Correct Option
Explanation
Solve: -7 < 4n ≤ 8. Divide by 4: -1.75 < n ≤ 2. Integers: -1, 0, 1, 2.
67
What are their present ages? (CSS-2024)
A. 8 and 40
B. 7 and 35
C. 6 and 30
D. None of these
Discuss
Save
Correct Option
Explanation
Let son’s age = x, man’s = 5x. Four years ago: (x - 4)(5x - 4) = 52. Solve: 5x^2 - 24x + 16 = 52, 5x^2 - 24x - 36 = 0. Discriminant: 576 + 720 = 1296, x = [24 ± 36]/10 = 6 or -1.2. x = 6 gives ages 6, 30, but check fails: (6-4)(30-4) = 2×26 = 52. Correct, but not in options; likely error.
