Telangana Police SI Mock Test - 3 - Question 1
Save

If x + 1/x = 25, find the value of x – 1/x.

Detailed Solution: Question 1

Given:

x + 1/x = 25

Concept Used:

If x + 1/x = p then, x – 1/x = √(p2 – 4)

Calculation:

It is given that x + 1/x = 25

We know that if x + 1/x = p then, x – 1/x = √(p2 – 4)

⇒ x – 1/x = √(252 – 4)

⇒ x – 1/x = √(625 – 4)

⇒ x – 1/x = √621

∴ value of x – 1/x is √621.

Directions: Each of the following consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.

There are six friends namely K, L, M, N, O and P. Who is the shortest among all?
Statement I: M is shorter than only P. K is taller than both L and N.
Statement II: M is shorter than P and L. K is shorter than P but taller than L. O is shorter than K but not taller than M. P is not tallest.

Detailed Solution: Question 8

From Statement I:
M is shorter than only P. K is taller than L and N.
Case1: P > M > K > N > L
Case2: P > M > K > L > N
Here, we cannot determine who is the shortest, either L or N is the shortest person. Also, we don’t know the position of O here.
From Statement II:
We have, M is shorter than both P and L. K is shorter than P but taller than L. O is shorter than both K and M. P is not tallest.
N > P > K > L > M > O
Here, O is the shortest person.
Hence option B is correct.

A kite is flying at a tallness of 75 m from the level of ground, joined to a string slanted at 60° to the level. The string's length is:

Detailed Solution: Question 12


Let AB be the kite and AC be the level ground
So that BC - AC.
At that point, ∠BAC = 60°and BC = 75m. Let AB = x meters.
Presently AB/BC = coses60° = 2/ √3
=> x/75 = 2/√3 => x = 150/√3 = 150 * √3/3 = 50 √3m.
∴ Length of the string = 50 √3m.

Q. Who is sitting between C and D, when counted from the left of C?

Detailed Solution: Question 13

From the common explanation, we get E is sitting between C and D.
Hence, Option C is correct.
Final Arrangement:

Common explanation:
References:
Six person A, B, C, D, E and F sit around a triangular table.
One person sits at each corner of the table facing away from the centre while one person sits at the middle of each edge facing toward the centre.
Inferences:
So, we need to arrange as follows to accommodate the information as stated in the question,

References:
Three persons sit between C and D, who is not facing the centre.
Inferences:
From the above reference, we get two different cases:
Case 1:

Case 2:

References:
F sits third to the left of C.
A sits second to the left of E.
A is not an immediate neighbour of D.
Inferences:
So, from this case 2 will be eliminated as A is not an immediate neighbour of D.
Case 1:

Case 2: (Eliminated)

Hence, Case 1 is the final arrangement.

Pipe A can fill a tank of 1000 liters in 150 minutes. In how many minutes can it fill a tub of 60 liters while working with 5% of its efficiency?

Detailed Solution: Question 15

First, find the normal rate of Pipe A:

  • Pipe A fills 1000 liters in 150 minutes.
  • Hence, its normal rate = 1000 / 150 = 6.6667 liters per minute.

Next, if it works at only 5% efficiency, its rate becomes:

  • 5% of 6.6667 = 0.05 × 6.6667 = 0.3333 liters per minute (approximately).

Finally, to fill 60 liters at this reduced rate:

  • Time required = 60 / 0.3333 ≈ 180 minutes.

Answer: 180 minutes (Option c).

Hence, Option C is correct.

Distance between S and P = √(PQ2 + QS2)
SP = √(62 + 82)
SP = √(36 + 64)
SP = √100
SP = 10 km
Hence, S is 10 km in South-East with respect to P.

Two trains running at speeds of 36 kmph and 54 kmph, respectively cross each other in 10 sec, if they run in opposite directions. When they run in the same direction, a person sitting in the faster train observes that he crossed the other train in 20 seconds. Find the lengths of the two trains.

Detailed Solution: Question 25

Let length of slower train-1 be L1 and length of faster train-2 be L2.
Relative speed when trains run in opposite directions = (54 + 36) × 5/18 = 25 m/s
So, 10 = (L1 + L2)/25
L1 + L2 = 250 ........(1)
Relative speed when trains run in the same direction = (54 - 36) × 5/18 = 5 m/s
Now,
20 = L1/5
L1 = 100 m ..........(2)
Put (2) in (1),
L2 = 150 m
