  1. AOption (a)

    312

  2. BOption (b)

    324

  3. COption (c)

    210

  4. DOption (d)

    102

View answer & explanation

Correct answer

Answer: (d)D.

102

Why this answer is correct

1st Equation:

4 * 7 * 2 = 361

(4 - 1) = 3

(7 - 1) = 6

(2 - 1) = 1

When concatenating these results (3, 6,1) gives 361.

2nd Equation:

5 * 9 * 1 = 480

(5 - 1) = 4

(9 - 1) = 8

(1 - 1) = 0

When concatenating these results (4, 8, 0) gives 480.

Similarly, 2 * 1 * 3 = ?

(2 - 1) = 1

(1 - 1) = 0

(3 - 1) = 2

So, when concatenating these results (1, 0, 2) gives 102.

Hence, 102 is the correct answer.

Question 6

    3

  4. DOption (d)

    2

View answer & explanation

Correct answer

Answer: (b)B.

1

Why this answer is correct

From dice 1 and 3 (from left to right) we conclude that 1, 6, 5 and 4 lie adjacent to 3. Therefore, 2 must lie opposite 3.

From positions 2 and 3 (from left to right) we conclude that 1, 3, 2 and 5 lie adjacent to 4. Therefore, 6 must lie opposite 4.

So face which will be opposite to face ‘5’ is ‘1’.

Hence, the answer is ‘1’.

Why this answer is correct

  1. Logic → Biological → can be formed.

  2. Globe → Biological → cannot be formed as there is no letter ‘e’.

  3. Bail → Biological → can be formed.

  4. Bill → Biological → can be formed.

Hence, word ‘Globe’ cannot be formed.

Question 8

In the following question, select the related letters from the given alternatives.

KLMN : IJKL : : TUVW : ?

  1. AOption (a)

    RSUT

  2. BOption (b)

  4. DOption (d)

    RSTU

View answer & explanation

Correct answer

Answer: (d)D.

RSTU

Why this answer is correct

Logic:

K - 2 = I, L - 2 = J, M - 2 = K, N - 2 = L

Similarly;

T - 2 = R, U - 2 = S, V - 2 = T, W - 2 = U

Hence, RSTU is the correct answer.

Question 9

In the given figure, how many are musical toys?

  1. AOption (a)

    53

  2. BOption (b)

    61

    15 S 28 Q 4 P 2 = 27

View answer & explanation

Correct answer

Answer: (b)B.

15 S 16 Q 2 P 4 = 47

Why this answer is correct

Let us check all equation;

SymbolsPQRS
Meaning×÷-+
<br>
  1. 18 R 60 Q 15 S 2 = 8

On changing symbols

→ 18 - 60 ÷ 15 + 2 = 8

→ 18 - 4 + 2

12 ≠ 8

  1. 15 S 16 Q 2 P 4 = 47

On changing symbols

→ 15 + 16 ÷ 2 × 4 = 47

→ 15 + 8 × 4

→ 15 + 32

→ 47 = 47

  1. 3 P 5 R 18 Q 3 = 6

On changing symbols

→ 3 × 5 - 18 ÷ 3 = 6

→ 15 - 6 = 6

9 ≠ 6

  1. 15 S 28 Q 4 P 2 = 27

On changing symbols

→ 15 + 28 ÷ 4 × 2 = 27

→ 15 + 14 = 27

29 ≠ 27

Hence, ‘15 S 16 Q 2 P 4 = 47’ is the correct equation.

Question 14

The ratio of present ages of P and Q is 5 : 8. Three years later their ages will be in ratio 8 : 11. What is the present age (in years) of Q?

  1. AOption (a)

  2. BOption (b)

    11

  3. COption (c)

    14

  4. DOption (d)

    8

View answer & explanation

Correct answer

Answer: (d)D.

8

Why this answer is correct

Let present ages of P and Q be 5k and 8k respectively.

Three years later their ages will be in ration 8 : 11

Then;

(5k + 3)/(8k + 3) = 8/11

→ (5k + 3) × 11 = (8k + 3) × 8

→ 55k + 33 = 64k + 24

→ 64k - 55k = 33 - 24

9k = 9

k = 1

Present age of Q is 8 × 1 = 8 years

Hence, the correct answer is 8.

  4. DOption (d)

    2000

View answer & explanation

Correct answer

Answer: (c)C.

2400

Why this answer is correct

Given:

A can do a work in 8 days.

B can do the same work in 10 days.

C can do the same work in 12 days.

All three of them do the same work together and they are paid Rs. 7400.

Formula used:

W = E × T     Where, W = Work, E = Efficiency, and T = Time

Calculation:

Let the total work be a units

Work done by A in 1 day = a/8

Work done by B in 1 day = a/10

Work done by C in 1 day = a/12

Ratio of work done by A, B and C:

⇒ A : B : C = 1/8 : 1/10 : 1/12

⇒ A : B : C = 15 : 12 : 10

Total amount paid to them = Rs. 7400

Share of B = Rs. 7400 × (12)/(15 + 12 + 10)

Share of B = Rs. 7400 × (12)/(37)

Share of B = Rs. 2400

∴ The share (in Rs.) of B is 2400.

  4. DOption (d)

    3985/9

View answer & explanation

Correct answer

Answer: (a)A.

2431/7

Why this answer is correct

Given: x + 1/x = 17

We know that: (x + 1/x)3 = x3 + (1/x)3 + 3(x)(1/x) (x + 1/x)

⇒ x3 + (1/x)3 = (x + 1/x)3 – 3(x + 1/x)

⇒ x3 + (1/x)3 = 173 – 3(17)

⇒ x3 + (1/x)3 = 4862

To find: [x4 + (1/x2)]/x2 - 3x + 1

Taking x common from both numerator and denominator, we get

⇒ x [x3 + (1/x)3]/x[x + 1/x – 3]

Substituting values

⇒ 4862/(17 – 3)

⇒ 4862/14 = 2431/7

∴ the correct option is 1)

View answer & explanation

Correct answer

Answer: (b)B.

32

Why this answer is correct

Total runs conceded by bowler in 5 matches = 5 × 45 = 225

⇒ Total runs conceded by bowler in other 4 matches = 4 × 15.75 = 63

⇒ Total runs conceded by bowler in 9 matches = 225 + 63 = 288

⇒ Average runs conceded by the bowler in 9 matches = 288/9 = 32

∴ The average runs conceded by the bowler in 9 matches is 32

Since all the ratios have the values: 1, 2, 3, 4, 5

⇒ LCM of 1, 2, 3, 4 and 5 = 1 × 2 × 2 × 3 × 5 = 60

Taking B as 60, we get

So, A : B : C : D = 24 : 60 : 45 : 22.1

Hence, A : C : D = 24 : 45 : 22.1

Dividing by 1.5

⇒ A : C : D = 16 : 30 : 15

∴ the correct option is 4)

    14

View answer & explanation

Correct answer

Answer: (d)D.

14

Why this answer is correct

Here, we have 3 right angled triangles

⇒ ∆BAC, ∆CDA and ∆BDA

So, applying Pythagoras theorem in all 3 triangles, we get

⇒ AB2 + AC2 = BC2………..(i)

⇒ AD2 + CD2 = AC2………..(ii)

⇒ AD2 + BD2 = AB2………(iii)

Here (ii) + (iii) = (i)

⇒ 2AD2 + CD2 + BD2 = BC2

Putting the values of BD = 7 cm, CD = 28 cm and BC = 35 cm

⇒ 2AD2 = 352 – 282 – 72

⇒ 2AD2 = 392

⇒ AD2 = 196

⇒ AD = 14

∴ the correct option is 4)

  4. DOption (d)

    42.84°

View answer & explanation

Correct answer

Answer: (b)B.

32.4°

Why this answer is correct

Since, 15% of total time is spent on quality check.

Percentage of time taken for quality check from all other processes

= 15/6 = 2.5%

⇒ Percent of time taken by seats = 6 - 2.5 = 3.5%

⇒ Percent of time taken by glass = 8 - 2.5 = 5.5%

⇒ Percent of time taken by both seats and glass = 3.5 + 5.5 = 9%

Required sectorial angle = (9/100) × (360) = 32.4°

∴ the correct option is 2.

View answer & explanation

Correct answer

Answer: (d)D.

4

Why this answer is correct

Initial Principal = Rs.400, Initial Amount = Rs. 448

Time period = 2 years

⇒ Amount = P + (P × R × T)/100

⇒ 448 = 400 + (400 × R × 2)/100

⇒ 448 – 400 = 8R

⇒ 48 = 8R

⇒ R = 48/8 = 6%

New Principal = Rs. 550, New Amount = Rs. 682

⇒ Amount = P + (P × R × T)/100

⇒ 682 = 550 + (550 × 6 × T)/100

⇒ 132 = 33 T

⇒ T = 4

∴ the correct option is 4)

2

Why this answer is correct

Given: √[(1 + x)/x] - √[x/(1 + x)] = 1/√6

Squaring both sides

⇒ [(1 + x)/x] + [x/(1 + x)] – 2 = 1/6

⇒ [(1 + x)2 + x2]/[(x + 1)x] – 2 = 1/6

⇒ [1 + 2x2 + 2x – 2x2 – 2x]/[(x + 1)x] = 1/6

⇒ 6 = x2 + x

⇒ x2 + x – 6

⇒ x2 + 3x – 2x – 6 = 0

Correct answer

Answer: (b)B.

14

Why this answer is correct

Let the cost price be a

⇒ The marked price of article = a + (20/100)a = 1.2a

⇒ Discount on marked price = 5%

⇒ Selling price = 1.2a – (5/100)1.2a

⇒ Selling price = 1.2a – 0.06a

⇒ Selling price = 1.14a

So, profit percent = [(1.14a – a)/a] × 100

⇒ 14%

∴ the correct option is 2)

Question 69

In the given figure, ABC is a triangle in which, AB = 10 cm, Ac = 6 cm and altitude AE = 4 cm. If AD is the diameter of the circumcircle, then what is the length (in cm) of circumradius?

  1. AOption (a)

    3

  2. BOption (b)

    7.5

  3. COption (c)

    12

  4. DOption (d)

    15

View answer & explanation

Correct answer

Answer: (b)B.

7.5

Why this answer is correct

Circumradius = (AB × BC × AC)/ 4 × (1/2) × BC × AE

⇒ Circumradius = (a × 10 × 6)/4 × (1/2) × a × 4

⇒ Circumradius = 15/ 2

⇒ Circumradius = 7.5 cm

∴ Answer is 7.5 cm

ALTERNATE METHOD:

Join BD

⇒ ∠ADB = ∠ΔACB,    (Angles made by the same chord AB)

Also, ∠DBA = ∠CEA = 90°

So, ΔABD = ΔAEC are similar triangles

⇒ AD/AB = AC/AE

⇒ AD/10 = 6/4

⇒ AD = 15 cm

Since, AD = 2 × circumradius

⇒ Circumradius = 15/2 = 7.5 cm

∴ the correct option is 2)

Question 70

  4. DOption (d)

    10

View answer & explanation

Correct answer

Answer: (c)C.

8

Why this answer is correct

Given: initial speed (a) = 21 km/hr

⇒ Increase in speed every hour (d) = 3 km/hr

This is an A.P. with initial number (a) = 21 and difference (d) = 3

Also, the sum of AP = n/2[2a + (n – 1)d]

⇒ 252 = n/2[2 × 21 + (n – 1)3]

⇒ 3n2 + 39n - 504 = 0

⇒ n = 8, -21

Since, number of hours can’t be negative

∴ the correct option is 3)

Question 71

If tanA = 1/2 and tanB = 1/3, then what is the value of tan(2A + B)?

  4. DOption (d)

    9

View answer & explanation

Correct answer

Answer: (b)B.

3

Why this answer is correct

We know that

tan(A + B) = [(tanA + tanB)/1 - tanAtanB]

So, tan(2A + B) = [(tan2A +tanB)/1 - tan2AtanB]

Also, tan2A = 2tanA/(1 – tan2A)

⇒ tan2A = 2(1/2)/(1 – (1/2)2)

⇒ tan2A = 4/3

⇒ tan(2A + B) = [(4/3 + 1/3)/1 - (4/3)(1/3)]

⇒ tan(2A + B) = (5/3)/(5/9) = 3

⇒ tan(2A + B) = 3

∴ the correct option is 2)

Question 72

  3. COption (c)

    40

  4. DOption (d)

    35

View answer & explanation

Correct answer

Answer: (d)D.

35

Why this answer is correct

Percent of total hours taken by engine and tyres = 40 + 11 = 51%

⇒ 51% of total hours = 127.5 hours

⇒ Total hours = (127.5 × 100)/51

⇒ Total hours = 250 hours

Difference in time taken by frame and glass = 250(22 – 8)/100 = 250 × 14/100 = 35

∴ the correct option is 4)

Question 73

Correct answer

Answer: (a)A.

-1 or 2

Why this answer is correct

Given: 2[x2 + (1/x2)] – 2[x – (1/x)] – 8 = 0

⇒ 2{[x – (1/x)]2 + 2} – 2[x – (1/x)] – 8 = 0

Let x – (1/x) be a

⇒ 2{a2 + 2} – 2a – 8 = 0

⇒ 2a2 – 2a – 4 = 0

⇒ a2 – a – 2 = 0

⇒ a = -1, 2

∴ the correct option is 1)

  4. DOption (d)

    46

View answer & explanation

Correct answer

Answer: (a)A.

36

Why this answer is correct

Given:

Radius of cylinder is increased by 25%

Let the initial radius be r, initial height be h and final height be H

Then, the new radius becomes = 1.25r

Since, previous volume = present volume

⇒ πr2h = π(1.25r)2H

⇒ h = (1.25)2H

⇒ h = 1.5625H

⇒ H = h/1.5625

⇒ H = 0.64h

 % decrease in height = (h – 0.64h) x 100/ h

= 0.36 x 100

= 36.

View answer & explanation

Correct answer

Answer: (b)B.

17

Why this answer is correct

Let radius of the smaller circle be r

Here, ∠RPQ = ∠SPO, ∠PSO = ∠PRQ

If we join SO and QR then,

So, ΔPSO and ΔPRQ are similar triangles

⇒ PO/PS = PQ/PR

⇒ 2r/PS = 4r/34

⇒ PS = 17 cm

∴ the correct option is 2)

  4. DOption (d)

    No improvement

View answer & explanation

Correct answer

Answer: (d)D.

No improvement

Why this answer is correct

The correct answer is "No improvement". 

Key Points

  • The given sentence implies that the artist is so familiar with the painting that he doesn't need to see it to recreate it.
  • The phrase "with his eyes closed" is a figure of speech that suggests he could do it easily without actively looking, based on his experience and expertise.
  • Taking a look at the proposed alternatives:
  • "With his arms full" would imply physical constraint or challenge which doesn't seem to match the context here.
  • "With his eyes opened" is the normal state for painting and doesn't convey the idea of effortlessness or mastery.
  • "With his mind blank" might suggest the ability to perform tasks from muscle memory, but it lacks the connotation of mastery conveyed by "eyes closed".
  • So after analyzing all the options, it can be concluded that no improvement is needed in the phrase "with his eyes closed" as it accurately communicates the intended meaning.
  • Hence, the correct answer is "Option 4".

View answer & explanation

Correct answer

Answer: (b)B.

let you have

Why this answer is correct

The correct answer is ‘let you have’.

The phrase ‘allow you’ does not fit in with the sentence and must be changed.

Option 2, ‘let you have’ indicates that following the conditional, she will probably permit taking the notes.

Option 3 is incorrect because of the use of ‘to’, which makes the sentence grammatically incorrect.

Hence, the correct sentence is:

‘If you talk to her nicely, she will probably let you have her notes’.

Correct answer

Answer: (c)C.

QSPR

Why this answer is correct

The correct answer is QSPR.

Q will be the first part, followed by S as the two sentences talk about the law of nature and its context.

Followed by S will be P, since R has to come last.

R must come at the end because it uses ‘this’, in reference to something, which can only be P.

Thus, the correct combination is QSPR, as seen in Option 3.
