Try these sample questions to review concepts for the Military Institute Entrance (Tajikistan) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 40+ question experience with AI tutoring.
1Solve 4x + 15 = 39.
A.x = 13.5
B.x = 6
C.x = 24
D.x = 9.75
Explanation: Subtracting 15 gives 4x = 24. Dividing by 4 gives x = 6, and substituting it into the original equation gives 39.
2A rectangular ground measures 150 m by 80 m. What is its perimeter?
A.460 m
B.310 m
C.12,000 m
D.230 m
Explanation: A rectangle has two sides of each length. Its perimeter is 2(150 + 80) = 460 m.
3A vehicle covers 240 km at a constant speed of 60 km/h. How long does the journey take?
A.4 h
B.3 h
C.5 h
D.0.25 h
Explanation: Travel time is distance divided by speed. The journey takes 240/60 = 4 h.
4Evaluate sin²(30°) + cos²(30°).
A.0.5
B.2
C.1
D.0.25
Explanation: The identity sin² θ + cos² θ = 1 applies to the same angle θ. Here the terms are 1/4 and 3/4, whose sum is 1.
5What is the hypotenuse of a right triangle with perpendicular legs 9 cm and 12 cm?
A.21 cm
B.15 cm
C.108 cm
D.225 cm
Explanation: Pythagoras' theorem gives c² = 9² + 12² = 225. Taking the positive square root gives c = 15 cm.
6For a ≠ 0, simplify (a³ × a⁵)/a².
A.a¹⁵
B.a⁸
C.a¹⁰
D.a⁶
Explanation: Multiplication adds exponents and division subtracts them when the base is the same. The resulting exponent is 3 + 5 - 2 = 6.
7Find both roots of 7x² - 23x + 6 = 0.
A.3 and 2/7
B.-3 and -2/7
C.2 and 3/7
D.3 and 7/2
Explanation: The polynomial factors as (7x - 2)(x - 3). The zero-product property gives x = 2/7 or x = 3.
8For u = (3, 4) and v = (5, -2), what is the dot product u · v?
A.23
B.-7
C.7
D.15
Explanation: Multiply matching components and add: u · v = 3 × 5 + 4 × (-2). This gives 15 - 8 = 7.
9Solve 2x + 3y = 19 and 3x - y = 1 simultaneously.
A.x = 5, y = 3
B.x = 3, y = 4
C.x = 4, y = 2
D.x = 2, y = 5
Explanation: The second equation gives y = 3x - 1. Substituting into the first gives 11x = 22, so x = 2 and y = 5.
10An arithmetic progression starts at 5 and has common difference 4. What is its tenth term?
A.45
B.41
C.40
D.36
Explanation: The nth term is a₁ + (n - 1)d. There are nine increments before the tenth term, giving 5 + 9 × 4 = 41.
