#5041
The Chief Justice of Supreme Court of Pakistan is appointed by the: (CSS-2024)
(a) President
(b) Prime Minister
(c) Majority vote in the Parliament
(d) None of these
Explanation: The President appoints the Chief Justice, per Pakistan’s Constitution (Article 175A). Mathematics (Q110–Q128)
#5042
What are their present ages? (CSS-2024)
(a) 8 and 40
(b) 7 and 35
(c) 6 and 30
(d) None of these
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.
#5043
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
Explanation: Solve: -7 < 4n ≤ 8. Divide by 4: -1.75 < n ≤ 2. Integers: -1, 0, 1, 2.
#5044
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
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,
#5045
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
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.
#5046
Name the regular polygon that has an exterior angle of 36. (CSS-2024)
(a) Pentagon
(b) Hexagon
(c) Decagon
(d) None of these
Explanation: Exterior angle = 360/n. Then 360/n = 36, n = 10 (decagon).
#5047
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
Explanation: Perimeter = πr + 2r = 700π + 1400 ≈ 2200 + 1400 = 3600 m = 3.6 km. Option C (2.9 km) seems incorrect; likely a typo.
#5048
Given: PQS, QRT, RSU, STV ... What should follow? (CSS-2024)
(a) TUW
(b) SUV
(c) STU
(d) None of these
Explanation: Pattern: First letter increases by 1 (P, Q, R, S, T), second by 1 (Q, R, S, T, U), third by 2 (S, T, U, V, W). Next: TUW.
#5049
What is the next term in the series? 11, 20, 35, 56, 83 (CSS-2024)
(a) 108
(b) 122
(c) None of these
Explanation: Differences: 9, 15, 21, 27 (+6 each). Next: 27 + 6 = 33. 83 + 33 = 116. Option B (122) likely a typo.
#5050

(a) The output voltage is greater than the input voltage
(b) The output voltage is equal to the input voltage
(c) The output voltage is less than the input voltage
(d) None of these
Explanation: Duplicate of Q1. A step-up transformer increases voltage due to more secondary coil turns (Halliday & Resnick).
