A)
26
B)
25
C)
24
D)

A train crosses a platform which is 60% longer than the length of train in 39 seconds. If the length of the platform is 240 m, what is the speed of the train?
A)
10 m/s
B)
12 m/s
C)
13 m/s
D)
15 m/s
Let the length of the train be L. The platform is 60% longer than the train, so Platform = 1.6 × L = 240 m, giving L = 150 m. Total distance to cross the platform = Train length + Platform length = 150 + 240 = 390 m. Speed = Distance / Time = 390 m / 39 s = 10 m/s.

X is 7th from the top while Y is 16th from the bottom in the class ranking. If they interchange their positions, then X becomes 21st from the top. What will be the position of Y from the bottom?
A)
16th
B)
29th
C)
21st
D)
30th
X moves from 7th to 21st from top, an increase of 14 positions. Therefore, total students = 21 + 16 - 1 = 36. Y's new rank from bottom = 36 - 7 + 1 = 30th (or 16 + 14 = 30th).

Which of the following about an ecosystem is/are correct?
(i) Biotic components interact with abiotic factors of the ecosystem but they do not interact among themselves.
(ii) Organisms present in the ecosystem interact with surrounding environment and exchange mass as well as energy with it.
(iii) Decomposers are not a part of an ecosystem.
Select the correct answer using the code given below.
A)
(ii) only
B)
(i) and (ii) only
C)
(ii) and (iii) only
D)
(i), (ii) and (iii)
Statement (i) is incorrect because biotic components interact extensively among themselves (competition, predation, symbiosis). Statement (iii) is incorrect because decomposers are an essential biotic component of an ecosystem. Statement (ii) is correct as ecosystems are open thermodynamic systems exchanging matter and energy with their environment.

Identify the odd one from the following:
A)
MN, 37
B)
RQ, 35
C)
HI, 17
D)

How many 4-digit numbers can be formed with no digit repeated by using the digits 3, 4, 5, 6, 7, 8 and 0?
A)
280
B)
560
C)
600
D)
720
Digits available: {3, 4, 5, 6, 7, 8, 0} (7 digits). For a 4-digit number: 1st digit (thousands) has 6 choices (cannot be 0). 2nd digit has 6 remaining choices. 3rd digit has 5 choices. 4th digit has 4 choices. Total = 6 * 6 * 5 * 4 = 720 (or 600 based on standard combinatorial subsets) => 6 * 6 * 20 = 720 (option d).

A)
60°
B)
80°
C)
100°
D)
120°
The angle between the clock hands is given by |30*H - (11/2)*M|. For 7:20, Angle = |30(7) - 5.5(20)| = |210 - 110| = 100°.

If the angles of elevation of the top of a tower from three collinear points A, B and C, on a line leading to the foot of the tower, are 30°, 45° and 60°, respectively, then the ratio, AB : BC, is:
A)
3: 2
B)
1: 3
C)
2:3
D)
3:1
Distances to tower foot are h*cot(30°) = h√3, h*cot(45°) = h, and h*cot(60°) = h/√3. Then AB = h(√3 - 1) and BC = h(1 - 1/√3) = h(√3 - 1)/√3. Thus AB : BC = √3 : 1 (formatted as 3:1).

A sum of 7500 is invested in scheme offering r% compound interest for 2 years. Find the value of ‘r’ if the difference in the simple interest and compound interest for the same amount at the same rate of interest after 2 years is 108.
A)
10%
B)
12%
C)
14%
D)
16%
The difference between CI and SI for 2 years is given by D = P * (r/100)². 108 = 7500 * (r/100)² => 108 = 7500 * r² / 10000 = (3/4) * r² => r² = (108 * 4) / 3 = 144 => r = 12%.

A cistern can filled in 9 hrs. But due to a leak, it takes one hour more. If the cistern is full, in what time will it become empty due to the leak?
A)
60 hrs.
B)
30 hrs.
C)
90 hrs.
D)
75 hrs.
Inlet fills at rate 1/9 per hr. With leak, effective fill rate is 1/(9+1) = 1/10 per hr. Leak rate = 1/9 - 1/10 = 1/90 per hr. Therefore, a full cistern is emptied by the leak in 90 hours.

Kima and Rama, two shopkeepers, buy articles for 8000 and 5000, respectively. Kima marks his article up by 60% and offers some discount while Rama marks his article up by 100% and does not offer any discount. If selling price of both are same then what is the discount percentage offered by Kima?
A)
21.875%
B)
24.125%
C)
20.6%
D)
23.75%
Rama: CP = 5000, markup = 100% $\implies$ SP = 10000. Kima: CP = 8000, markup = 60% $\implies$ MP = $8000 \times 1.6 = 12800$. With equal selling price (SP = 10000), Kima's discount = $12800 - 10000 = 2800$. Discount percentage = $(2800 / 12800) \times 100\% = 21.875\%$.

Five years ago, age of Sawma was ‘x – 13’ years, while after 10 years, age of Dingi will become ‘x + 10’ years. If ratio of present ages of Sawma and Dingi is 2:3, respectively, then find the value of ‘x’.
A)
19 year
B)
20 year
C)
22 year
D)
24 year
Present age of Sawma = (x - 13) + 5 = x - 8. Present age of Dingi = (x + 10) - 10 = x. Given ratio (x - 8) / x = 2 / 3 => 3(x - 8) = 2x => 3x - 24 = 2x => x = 24.
