Correct answer

Answer: (a)A.

518

Why this answer is correct

Given: 1008 : 8 :: ? : 6 :: 220 : 4

The logic followed here is:

1008 : 8 → (8 + 2)3 + 8 = 103 + 8 = 1000 + 8 = 1008

220 : 4 → (4 + 2)3 + 4 = 63 + 4 = 216 + 4 = 220

Similarly,

? : 6 → (6 + 2)3 + 6 = 83 + 6 = 512 + 6 = 518

Hence, 518 is the correct answer.

View answer & explanation

Correct answer

Answer: (b)B.

(697, 13, 866)

Why this answer is correct

Given: (541, 14, 737)

The logic followed here is:

(541, 14, 737) → 737 - 541 = 196 → 196=14 \sqrt{196} = 14

Now, by checking options:

(1) (832, 8, 895) → 895 - 832 = 63 → 63≠8\sqrt{63} \neq 8

(2) (697, 13, 866) → 866 - 697 = 169 → 169=13\sqrt{169} = 13

(3) (635, 18, 924) → 924 - 635 = 289 → 289=17≠18\sqrt{289} = 17 \neq 18

(4) (432, 25, 1108) → 1108 - 432 = 676 → 676=26≠25\sqrt{676} = 26 \neq 25

Hence, (697, 13, 866) is the correct answer.

View answer & explanation

Correct answer

Answer: (d)D.

÷, +, −, ×, =

Why this answer is correct

Given: 1496 * 8 * 13 * 40 * 5 * 0

By substituting the signs option wise:

(1) ÷, −, +, ×, = 

→ 1496 ÷ 8 - 13 + 40 × 5 = 0

LHS = 1496 ÷ 8 - 13 + 40 × 5

= 187 - 13 + 40 × 5

= 187 - 13 + 200

= 387 - 13 

= 374 ≠ 0

LHS ≠ RHS

(2) ÷, +, =, −, × 

→ 1496 ÷ 8 + 13 = 40 - 5 × 0

LHS = 1496 ÷ 8 + 13

= 187 + 13 

= 200

RHS = 40 - 5 × 0

= 40 - 0

= 40

LHS ≠ RHS

(3) ÷, ×, =, +, − 

→ 1496 ÷ 8 × 13 = 40 + 5 - 0

LHS = 1496 ÷ 8 × 13

= 187 × 13

= 2431

RHS = 40 + 5 - 0

= 45 - 0

= 40

LHS ≠ RHS

(4) ÷, +, −, ×, = 

→ 1496 ÷ 8 + 13 - 40 × 5 = 0

LHS = 1496 ÷ 8 + 13 - 40 × 5

= 187 + 13 - 40 × 5

= 187 + 13 - 200

= 200 - 200

= 0

LHS = RHS

Hence, ÷, +, −, ×, = is the correct answer.

₹40

Why this answer is correct

Given: Rajesh purchased 6 mangoes, 3 bananas and 10 guavas in ₹136. If the ratio of the cost (per piece) of mangoes, bananas and guavas is 3 : 2 : 1.

Let:

The cost (per piece) of mangoes be 3x,

The cost (per piece) of bananas be 2x,

The cost (per piece) of guavas be x,

Then, according to the question,

6 (3x) + 3 (2x) + 10 (x)  = 136

18x + 6x + 10x = 136

34x = 136

x = 4

Then, the cost (per piece) of mangoes, banana, and guava is ₹12, ₹8, and ₹4 respectively.

Therefore, the cost of 1 mango, 2 bananas and 3 guavas = 12 × 1 + 8 × 2 + 4 × 3

= 12 + 16 + 12 

= ₹40

Hence, ₹40 is the correct answer.

  4. DOption (d)

    9024

View answer & explanation

Correct answer

Answer: (d)D.

9024

Why this answer is correct

Given:

The total sum of money = Rs. 31866

Ratio of A and B = 9 : 8

Ratio of A and C = 4 : 5

Calculation:

Let the total sum be x

Simplifying the ratios to get the same unit by cross multiplication

Ratio of A and B = (9 : 8) × 4

⇒ 36 : 32

Ratio of A and C = (4 : 5) × 9

⇒ 36 : 45

Ratio of A, B and C = 36 : 32 : 45

Total sum = Rs. (36x + 32x + 45x)

⇒ 113x = 31866

⇒ x = 282

The share of B = 32x = (32 × 282)

⇒ 9024

∴ The share of B is 9024

  4. DOption (d)

    80

View answer & explanation

Correct answer

Answer: (d)D.

80

Why this answer is correct

Given:

Time taken by A = 8 hours more than B

Distance = 160 km

A doubles the speed, he takes 3 hours more than B

Formula used:

Speed = Distance/Time

Calculation:

Let the speed be SA and SB

According to the question

⇒ 160/SA – 160/SB = 8......(1)

⇒ 160/2SA – 160/SB = 3 

⇒ 80/SA – 160/SB = 3 ....(2)

Multiplying equation (1) by 1/2 we get,

⇒ 80/SA – 80/SB = 4 .....(3)

Now,

Substituting equation (2) and (3) we get,

⇒ 80/SA – 160/SB = 3 and 80/SA – 80/SB = 4

⇒ 160/SB – 80/SB = 4 – 3

⇒  80/SB = 1

⇒ SB = 80 km/h

∴ The speed of B is 80 km/h

Question 53

    cosec2 θ

View answer & explanation

Correct answer

Answer: (c)C.

sec2 θ

Why this answer is correct

Given:

(√sec⁡2θ+ cosec2θ)(sin⁡θ(1+cos⁡θ)1+cos⁡θ−sin⁡2θ)(√{\sec^2 θ + \ cosec^2 θ)} \left( \frac{\sin θ ( 1+ \cos θ)}{1 + \cos θ - \sin^2 θ} \right)

Formula used:

Sec2θ = 1/cos2θ 

Cosec2θ = 1/sin2θ 

Sin2θ = 1 - cos2θ 

Calculation:

(√sec⁡2θ+ cosec2θ)(sin⁡θ(1+cos⁡θ)1+cos⁡θ−sin⁡2θ)(√{\sec^2 θ + \ cosec^2 θ)} \left( \frac{\sin θ ( 1+ \cos θ)}{1 + \cos θ - \sin^2 θ} \right)

⇒ (√1/cos2θ + 1/sin2θ) [sinθ(1 + cosθ)/(1 + cosθ – 1 + cos2θ)]

⇒ (√sin2θ + cos2θ)/cos2θ. sin2θ) [sinθ(1 + cosθ)/(cosθ(1 + cosθ)]

⇒ (1/sinθ. cosθ)/(sinθ/cosθ)

⇒ 1/cosθ × 1/cosθ 

⇒ 1/cos2θ 

⇒ sec2θ 

∴ The required value is sec2θ

Question 54

By selling an article for Rs. 640, a person loses 15% of its selling price. At what price (in Rs.) should he sell it to gain 15% on its cost price?

  1. AOption (a)

  2. BOption (b)

    836.60

  3. COption (c)

    832

  4. DOption (d)

    835

View answer & explanation

Correct answer

Answer: (a)A.

846.40

Why this answer is correct

Given:

The selling price of an article = Rs. 640

Loss = 15% of SP

Gain = 15% of CP

Formula used:

Gain% = (SP – CP)/CP × 100

Loss% = (CP – SP)/CP × 100

Calculation:

The SP of an article is Rs. 640

According to the question

CP = 640 × 15/100 + 640 = Rs. 736

Gain% = 15% = (SP – 736)/736

⇒ 736 + 0.15 × 736

⇒ 736 + 110.4

⇒ 846.40

∴ New selling price of an article is Rs. 846.40

  4. DOption (d)

    2425.5

View answer & explanation

Correct answer

Answer: (d)D.

2425.5

Why this answer is correct

Given:

The curved surface area of cylinder = 462 cm2

Base area of cylinder = 346.5 cm2

Formula used:

Base area of cylinder = πr2

Curved surface area of cylinder = 2πrh

Volume of cylinder = πr2h

Calculation:

Base area of cylinder = πr2

⇒ πr2 = 346.5 cm2

⇒ 22/7 × r2 = 346.5 cm2

⇒ r2 = 110.25 cm2

⇒ r = 10.5 cm

Now,

Curved surface area of cylinder = 2πrh

⇒ 2πrh = 462 cm2

⇒ 2 × 22/7 × 10.5 × h = 462 cm2

⇒ 462h/7 = 462 

⇒ h = 7 cm

Now,

Volume of cylinder = πr2h

⇒ 22/7 × 10.5 × 10.5 × 7 cm3

⇒ 16978.5/7 cm3

⇒ 2425.5 cm3

∴ Volume of cylinder is 2425.5

Formula used:

Cot 30° = √3

Cos 30° = √3/2

Cosec 60° = 2/√3

Tan 60° = √3

Calculation:

 34cot⁡230∘+cos⁡230∘−3cosec260∘+tan⁡260∘\frac{3}{4} \cot^2 30 ^\circ + \cos^2 30 ^\circ - 3 cosec^2 60^\circ + \tan^2 60^\circ 

⇒ 3/4 × (√3)2 + (√3/2)2 – 3 × (2/√3)2 + (√3)2

⇒ 3/4 × 3 + 3/4 – 3 × 4/3 + 3

⇒ 9/4 + 3/4 – 4 + 3

⇒ 12/4 – 4 + 3

⇒ 3 – 4 + 3

4

Why this answer is correct

Given:

x + y + z = 7

x2 + y2 + z2 = 85

x3 + y3 + z3 = 913

Formula used:

x3 + y3 + z3 – 3xyz = (x + y + z) (x2 + y2 + z2 – (xy + yz + zx)) .....(1)

(x + y + z)2 = x2 + y2 + z2 + 2(xy + yz + zx) ....(2)

Calculation:

⇒ 72 = 85 + 2(xy + yz + zx)

⇒ 49 – 85 =  2(xy + yz + zx)

⇒ -36 =  2(xy + yz + zx)

⇒ (xy + yz + zx) = -36/2

⇒ (xy + yz + zx) =-18

⇒ 913 – 3xyz = 7(85 + 18)

⇒ 913 – 7 × 103 = 3xyz

⇒ 913 – 721 = 3xyz

⇒ 192 = 3xyz

⇒ 64 = xyz

⇒ (4)3 = xyz3\rm \sqrt[3]{xyz}

∴ The value of xyz3\rm \sqrt[3]{xyz} is 4

View answer & explanation

Correct answer

Answer: (d)D.

9

Why this answer is correct

Given:

AB = 5 cm

BC = 6 cm

CA = 7 cm

Calculation:

Let R is the point where BC touches the circle.

BP = BR (lengths of tangents drawn from an external point to a circle are equal)

Similarly,

CR = CQ

AP = AQ

Now,

⇒ 2AQ = AP + AQ

⇒ 2AQ = AB + BP + AC + CQ = AB + AC + (BP + CQ)

⇒ 2AQ = AB + BP + AC + CQ = AB + AC + (BR + CR)

⇒ 2AQ = (5 + 6 + 7) = 18

⇒ AQ = 9 cm

Alternate Method

Formula used:

AQ = 1/2(Perimeter of ΔABC)

Calculation:

According to the question

AQ = 1/2(Perimeter of ΔABC)

⇒ AQ = 1/2 × (5 + 6 + 7)

⇒ 1/2 × 18 cm

⇒ 9 cm

∴ The length of AQ is 9 cm

Correct answer

Answer: (c)C.

25

Why this answer is correct

Given:

BE = 4 cm

EF = 6 cm

Calculation:

In ΔBED and ΔBFA

BE/BF = ED/FA = BD/BA

In ΔBFD and ΔBCA

BF/BC = FD/CA = BD/BA

Now,

BE/BF = BF/BC 

⇒ BF2 = BE × BC

⇒ (BE + EF)2 = BE × BC

⇒ (4 + 6)2 = 4 × BC

⇒ (10)2 = 4BC

⇒ 100 = 4BC

⇒ BC = 25 cm

∴ The value of BC is 25

Why this answer is correct

Calculation:

The total number of students enrolled for VC in institutes A, C and E in 2015 = (150 + 220 + 200)

⇒ 570

The total number of students enrolled foe VC in institutes B and D in 2017 = (200 + 180)

⇒ 380

Required ratio = (570 : 380)

  4. DOption (d)

    64

View answer & explanation

Correct answer

Answer: (b)B.

115.2

Why this answer is correct

Shortcut Trick

Since DE ∥ BC, ΔADE is similar to ΔABC.

Ratio of areas = (Ratio of corresponding sides)2

Area(ΔADE) : Area(ΔABC) = (DE)2 : (BC)2 = 52 : 82 = 25 : 64

25 units = 45 cm2 ⇒ 1 unit = 1.8 cm2

64 units = 64 × 1.8 = 115.2 cm2

∴ The correct answer is 115.2 cm2.

Alternate Method

Given: BC = 8 cm, DE = 5 cm, Area of ΔADE = 45 cm2

Formula: For similar triangles, Area1 / Area2 = (Side1 / Side2)2

⇒ In ΔABC, DE ∥ BC, ∴ ΔADE ∼ ΔABC (by AA similarity)

⇒ Area(ΔADE) / Area(ΔABC) = (DE / BC)2

⇒ 45 / Area(ΔABC) = (5 / 8)2

⇒ 45 / Area(ΔABC) = 25 / 64

⇒ Area(ΔABC) = (45 × 64) / 25

⇒ Area(ΔABC) = (9 × 64) / 5

⇒ Area(ΔABC) = 576 / 5 = 115.2 cm2

∴ The correct answer is 115.2 cm2.

Additional Information

Similar Triangles Property

The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides, altitudes, medians, or perimeters.

Basic Proportionality Theorem (BPT)

If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio (AD/DB = AE/EC).

AA Similarity Criterion

If two angles of one triangle are equal to two angles of another triangle, then the two triangles are similar.

Number less than between 250 and 200 = (26 – 12)

⇒ 14

Again,

Number less than 250 = 26

Number less than 300 = 34

Number less than between 300 and 250 = (34 – 26)

⇒ 8

Persons earn Rs. 200 or more but less than Rs. 300 = (14 + 8)

⇒ 22

∴ Required persons is 22

View answer & explanation

Correct answer

Answer: (a)A.

31

Why this answer is correct

Given:

The average of 8 consecutive even numbers in ascending order = 17

Formula used:

Sum of the observations/Number of observations

Calculation:

Let the 8 consecutive even numbers be (2a – 6), (2a – 4), (2a – 2), 2a, (2a +2), (2a + 4), (2a + 6) and (2a + 8)

Sum of 8 consecutive even numbers = (2a – 6) + (2a – 4) + (2a – 2) + 2a, (2a +2) + (2a + 4) + (2a + 6) + (2a + 8)

⇒ 16a + (-12 +20)

⇒ 16a + 8

Average sum of 8 consecutive even numbers = (16a + 8)/8 = 17

⇒ 8(2a + 1)/8 = 17

⇒ 2a + 1 = 17

⇒ 2a = (17 – 1)

⇒ 2a = 16

Now, putting the value in last three three numbers

⇒ (2a + 4) = (16 + 4) = 20

⇒ (2a + 6) = (16 + 6) = 22

⇒ (2a + 8) = (16 + 8) = 24

Again,

Sum of last three numbers, 36 and 53 = (20 + 22 + 24 + 36 + 53)

⇒ 155

Average of sum of last three numbers, 36 and 53 = (155/5)

⇒ 31

∴ The average of the last three numbers, 36 and 53 is 31

Shortcut Trick

Concept Used:

Average consecutive even,

If the number of terms is Odd then,

Average will be the middle term of it.

If the number of terms is Even then, 

Average will be the average of the middle pair.

Calculation:

According to the question, 

There are 8 consecutive even numbers, which have 17 as average. 

Hence the average of the middle pair is 17, 

Sum of middle pair = 17 × 2 = 34

Now the pair will be, 

16 + 18 = 34 (consecutive pair)

As there are 8 numbers and we have middle pair, 

Then all 8 numbers will be, 

10, 12, 14, 16, 18, 20, 22, 24, 

Average of last 3 and 36 & 53

⇒ (20 + 22 + 24 + 36 + 53)/5 = 155/5 = 31 

∴ The average of the last three numbers, 36 and 53 is 31

Correct answer

Answer: (c)C.

-36

Why this answer is correct

Given:

(54√2 x3 + 24√3 y3) ÷ (√18 x + √12 y) = Ax2 + By2 + Cxy

Formula used:

a3 + b3 = (a + b)(a2 + b2 – ab)

Calculation:

(54√2 x3 + 24√3 y3)/(√18 x + √12 y)

⇒ (54√2 x3 + 24√3 y3)/(3√2x + 2√3y)

⇒ 18x2 + 12y2 – 6√6 = Ax2 + By2 + Cxy

where A = (18), B = (12) and C = (-6√6)

Now,

The value of  A2 – (B2 + C2) = (18)2 – (12)2 + (6√6)2

⇒ 324 – (144 + 216)

⇒ 324 – 360

⇒ -36

∴ Required value is -36

    229

  4. DOption (d)

    319

View answer & explanation

Correct answer

Answer: (a)A.

209

Why this answer is correct

Given:

The marked price of an article = Rs. 1500

Discount = 20%

CP = Rs. 991

Formula used:

SP = MP × (100 – discount%)/100

Profit = SP – CP

Calculation:

According to the question

SP = 1500 – (100 – 20)/100

⇒ (1500 – 80/100)

⇒ SP = Rs. 1200

Now,

Profit = 1200 – 991

⇒ 209

∴ His profit is 209

View answer & explanation

Correct answer

Answer: (a)A.

-7

Why this answer is correct

Given:

 a2 + c2 + 17 = 2(a - 8b - 2b2) 

calculation:

 a2 + c2 + 17 = 2(a - 8b - 2b2) 

⇒ a2 + c2 + 17 = 2a – 16b – 4b2

⇒ a2 + 4b2 + c2 + 17 = 2(a – 8b)

⇒ a2 – 2a + 1 + 4b2 + 16b + 16 + c2 = 0

⇒ (a – 1)2 + (2b + 4)2 + c2 = 0

⇒ a = 1, b = -2 and c = 0

Now,

(a3 + b3 + c3) = (1)3 + (-2)3 + (0)3

⇒ 1 – 8 + 0

⇒ -7

∴ The required value is -7

Question 70

  3. COption (c)

    45°

  4. DOption (d)

    30°

View answer & explanation

Correct answer

Answer: (c)C.

45°

Why this answer is correct

Given:

Cos(A – B) = 32\frac{\sqrt 3}{2}

Cot(A + B) = 13\frac{1}{\sqrt 3}

Formula used:

Cos 30° = 32\frac{\sqrt 3}{2}

Cot 60° = 13\frac{1}{\sqrt 3}

Calculation:

According to the question

Cos(A – B) = 32\frac{\sqrt 3}{2}

⇒ (A – B) = 30° ......(1)

Cot(A + B) = 13\frac{1}{\sqrt 3}

⇒ (A + B) = 60° .....(2)

Now, adding both the equations we get,

⇒ (A – B) = 30° + (A + B) = 60° 

⇒ 2A = 90° 

⇒ A = 45°

Putting the value of A in equation (2)

⇒ 45° + B = 60° 

⇒ B = (60° – 45°)

⇒ B = 15° 

Now,

⇒ (2A – 3B) = (2 × 45° – 3 × 15°)

⇒ (90° – 45°)

⇒ 45° 

So, the value of (2A - 3B) is 45°

Question 71

  3. COption (c)

    8.3%

  4. DOption (d)

    10%

View answer & explanation

Correct answer

Answer: (a)A.

5.7%

Why this answer is correct

Given:

Students failed in school X = 20%

Number of students in school Y = 130% more than the number of students in school X

Students passed in both school = 90%

Calculation:

Let the number of students in school X be 100x

Number of failed students in school X = 20% of 100x

⇒ 20x

Number of passed students in school Y = (100x – 20x) = 80x

Number of students in school Y = 100x + 130% of 100x

⇒ 100x + (130/100 × 100x)

⇒ 100x + 130x

⇒ 230x

Total number of students in school X and school Y = (100x + 230x)

⇒ 330x

Number of passes students in both school = 90% of 330x

⇒ (90/100 × 330)

⇒ 297x

So, number of passed students in school Y = (297x – 80x)

⇒ 217x

Number of failed students in school Y = (230x – 217x)

⇒ 13x

Percentage of failed students in school Y = (13x/230x) × 100

⇒ (1300x/230x)

⇒ 5.65% ~ 5.7%

∴  The percentage of students who failed from school Y is 5.7%

  4. DOption (d)

    22

View answer & explanation

Correct answer

Answer: (d)D.

22

Why this answer is correct

Given:

2 men and 7 women can complete a work = 28 days

6 men and 16 women can complete a work = 11 days

Formula used:

Work = Efficiency × Time

Calculation:

According to the question

⇒ (2m + 7w) × 28 = (6m + 16w) × 11

⇒ 56m + 196w = 66m + 176w

⇒ 10m = 20w

⇒ m/w = 2/1

Total work = (2 × 2 + 7 × 1) × 28

⇒ (4 + 7) × 28

⇒ 11 × 28

⇒ 308

Time taken by 7 men to complete the work = (308/7 × 2)

⇒ (308/14)

⇒ 22 days

∴ Required days is 22.

    35

View answer & explanation

Correct answer

Answer: (b)B.

37

Why this answer is correct

Given:

Seven-digit number = 94x29y6

To be divided by 72

Concept used:

Divisibility rule of 8 = If the last three digits of a number are divisible by 8, then the number is completely divisible by 8

Divisibility rule of 9 = if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9

Calculation:

Now, putting the value of y = 1, 2, 4, 5, 6, 8 and 9, we can't divide the last 3 digit of seven-digit number by 8.

Only value of y will be 3 and 7

Now, if we take value of y as 3. Total sum of numbers should be divided by 9.

So, 9 + 4 + x + 2 + 9 + 3 + 6 = 33 + x

For sum to be divided by 9, the sum should be 36. So, value of x = 3

Now, value of both x and y = 3 which should not be the condition

So, value of y should be 7

Now, 9 + 4 + x + 2 + 9 + 7 + 6 = 37 + x

For sum to be divided by 9, the sum should be 45. So, value of x = 8

Now, Value of (2x + 3y) = (2 × 8 + 3 × 7)

⇒ 16 + 21 = 37

∴ The required value is 37

Question 74

A certain sum becomes Rs. 13650 at 15% p.a. simple interest after 2 years. What will be the amount (in Rs.) of the same sum after 1 year at the same rate of interest, if the interest is compounded half yearly? (nearest to a Rs.)

  1. AOption (a)

    10500

  2. BOption (b)

    11000

  3. COption (c)

    13625

  4. DOption (d)

    12134

View answer & explanation

Correct answer

Answer: (d)D.

12134

Why this answer is correct

Given:

Amount = Rs. 13650

Rate of Interest = 15%

Time = 2 Years

Formula used:

S.I = PRT/100

Amount = Principal + S.I

Calculation:

Let the Principal be Rs. x

S.I = Rs. (13650 – x)

According to the question,

⇒ (x × 15 × 2)/100 = 13650 – x

⇒ 3x/10 = 13650 – x

⇒ 3x = 136500 – 10x

⇒ 13x = 136500

⇒ x = 10500

Now, if rate of interest is compounded half yearly, the interest becomes half and Time becomes twice

So, Rate of interest = 15% ÷ 2 = 7.5%

Time period = 1 × 2 = 2 years

Now, amount after 1 year = Rs. 10500 × (107.5/100)2

⇒ Rs. 12134.0625 ≈ Rs. 12134

∴ Amount becomes Rs. 12134 after 1 year if compounded half yearly

    59°

  4. DOption (d)

    31°

View answer & explanation

Correct answer

Answer: (b)B.

49°

Why this answer is correct

Given:

∠QAX = 59° 

∠QBY = 72° 

Calculation:

<br>

 

 

∠OAX = 90°

⇒ ∠OAQ = 90° – (59°)

⇒ ∠OAQ =  31° 

Now, ∠OBY = 90°

⇒ ∠OBQ = 90° – (72°)

⇒ ∠OBQ = 18° 

 

Since, OB = OQ = OA

⇒ ∠OBQ = ∠OQB  = 18° (radius)

⇒ ∠OAQ = ∠OQA  = 31° (radius)

∠AQB = ∠OBQ  + ∠OAQ

⇒ ∠AQB = (31° + 18°)

⇒ ∠AQB = 49° 

∴ The measure of ∠AQB is 49°

Answer: (b)B.

A parrot that spoke five languages was bought by the man.

Why this answer is correct

The correct answer is 'A parrot that spoke five languages was bought by the man'.

Key Points

  • The given sentence is in the passive voice.
  • The sentence is very tricky we need to understand this from the basics. Here, in the sentence, "A parrot that could speak" is an ability of a parrot which was in the past tense.  These are skills or talents a person once had. In the past tense, English speakers almost always use “could.”
  • Example: In high school, she could beat anyone in a running race.
  • Again, we are talking about general skills or talents – not about a specific occasion. In this case, we don't have to use could instead we can use was/were/ or the past tense.
  • Example:- We were able to get a really good price on the car.
  • Now, coming back to the question the parrot had the ability in the past hence, we can represent it with the past tense as well.
  • In the given sentence, the main clause 'bought' will change into 'was bought'. The rest of the rules will remain the same in the question.

Correct Sentence: A parrot that spoke five languages was bought by the man
