a) 13 hrs
b) 14 hrs
c) 12 hrs
d) 15 hrs
b) 14 hrs Explanation: The time taken by train = Covered distance/ Average Speed; = 1050/75 = 14 hrs.
2. G is the centroid of ∆ABC. The medians AD and BE intersect at right angles. If the lengths of AD and BE are 9 cm and 12 cm respectively; then the length of AB (in cm) is?
a) 10
b) 10.5
c) 9.5
d) 11
a) 10
3. The minimum value of 2sin2θ + 3cos2θ is
a) 1
b) 3
c) 2
d) 4
c) 2 Explanation: 2sin2θ + 3cos2θ = 2*(sin2θ + cos2θ) + cos2θ = 2 + 0 =2;
4. If number of Vertices: edges and faces of a rectangular parallelopied are denoted by v, e and f respectively, the value of (v – e + f) is
a) 4
b) 2
c) 1
d) 0
b) 2 Explanation: The rectangular parallelepiped has 8 vertices, 12 edges, and 6 faces. Hence, v – e + f = 8 – 12 + 6 = 2;
5. 5 persons will live in a tent. If each person requires 16m2 floor area and 100m3 space for air then the height of the cone of smallest size to accommodate these persons would be?
a) 18.75 m
b) 16m
c) 10.25 m
d) 20 m
a) 18.75 m Explanation: The required area = 16 sq. m.; Suppose the radius of tent = r meter; => pi*r2 = 5*16; => r = 5.04 meter. (given) The volume of air = 5*100 m3; 1/3 * pi * r2 * h = 500; => h= 18.75 cms
6. If the altitude of an equilateral triangle is 12√3 cm, then its area would be:
a) 12 sq. cms.
b) 72 sq. cms.
c) 36√3 sq. cms.
d) 144√3 sq. cms.
d) 144√3 sq. cms. Explanation: The altitude of the equilateral triangle = (√3* side)/2; => Side = 24 cms. The required area = (√3* side * side)/4 = (√3* 24 * 24)/4 =144√3 sq. cms.
7. The difference between successive discounts of 40% followed by 30% and 45% followed by 20% on the marked price of an article is Rs. 12. The marked price of the article is:
a) Rs. 400
b) Rs. 200
c) Rs. 800
d) Rs. 600
d) Rs. 600 Explanation: Suppose, the marked price of the article= Rs. x; The price after 40% and 30% successive discounts = x*0.60*0.70 = 0.42x; The price after 45% and 20% successive discounts = x*0.55*0.80 = 0.44x; (Given), 0.02x = 12; => x = Rs. 600;
8. The area of the triangle formed by the graphs of the equation x=0, 2x + 3y=6 and x + y = 3 is:
a) 1 sq. unit
b) 1.5 sq. unit
c) 1 sq. unit
d) 4.5 sq. unit
b) 1.5 sq. unit
9. Among the equations x + 2y + 9 = 0; 5x – 4 = 0; 2y – 13 = 0; 2x – 3y = 0, the equation of the straight line passing through origin is-
a) 2x – 3y = 0
b) 5x – 4 = 0
c) x + 2y + 9 = 0
d) 2y – 13 = 0
a) 2x – 3y = 0 Explanation: x + 2y + 9 =0; (this line will intersect both the axes) 5x – 4 =0; (This line will be parallel to Y-axis) 2y – 13 =0; (This line will be parallel to X-axis) 2x – 3y =0; (This line will pass through the origin)
10. The HCF of x8 – 1 and x4 + 2×3 – 2x – 1 is:
a) x2 + 1
b) x + 1
c) x2 – 1
d) x – 1
c) x2 – 1 Explanation: x2 -1 =(x +1)*(x-1); => x = -1, 1; Both the values of x will satisfy the other equation; Hence, (x2 -1) will be the appropriate answer.
