The pattern followed here is :

• First number → Reverse of first number = Second number

​So,

• 9783 : 3879

​⇒9783 → Reverse order = 3879

Similarly,

• 1958 : ?

​⇒1958 → Reverse order = 8591

Hence, "8591" is the correct answer.

The figure that will replace the question mark (?) in the following figure series is shown below:

⇒Logic : The number of triangles in the box are increasing in an odd number series.

So,

As, the number of triangles in the box are increasing in an odd number series, therefore ;

• First box - 1 triangle
• Second box - 3 triangles
• Third box - 5 triangles
• Fourth box - 7 triangles ​

Thus, the only box which has 7 triangles is option- (2).

Hence, "Option - (2)" is the correct answer.

The least possible Venn diagram for the given statements is as shown below :

Conclusions:

I. Some actors are directors → Does not follow (As some actors are choreographers, all choreographers are producers and no producer is a director. So, some actors are directors is possible but not definitely true)

II. Not a single actor is a director → Does not follow (As some actors are choreographers, all choreographers are producers and no producer is a director. So, some actors are directors is possible but not definitely true)

∴ Here,

1. Elements i.e actors and director are same in both the conclusions.
2. Both the conclusions are individually does not follow(possible but not definitely true).
3. Conclusion I and II are complementary pair i.e Some and No

Hence, the correct answer is "Either conclusion I or II follows".

Additional InformationConditions of either or case

1. The elements should be same in both the conclusions
2. Both conclusions should possible but not definitely true.
3. One of the conclusion should be negative and one of the conclusion should be positive i.e complimentary pair.
4. Complimentary pairs :

• ​some + no and all + some not
• Some + Some not and All + no are not Complimentary pair.

The pattern followed here is : A certain code is assigned to each letter without any specific pattern.

So,

• ORGAN is coded as :

​

• OPERATE is coded as :

​

Similarly,

• GENERATOR is coded as :

​

As, from the given codes the common letters have same code, therefore each letter is given a certain code accordingly.

Hence, "DXCXWLSQW" is the correct answer.

Given : The sum of five consecutive multiples of 7 is 455.

Explanation :

Let the five consecutive multiple of 7 be = 7X, (7X + 7), (7X + 14), (7X + 21) and (7X + 28)

Where, X is a natural number.

So, according to the question :-

 7X + (7X + 7) + (7X + 14) + (7X + 21) + (7X + 28) = 455

35X + 70 = 455

35X = 455 - 70

35X = 385

X=11

Therefore, by the putting the value of 'X' the five consecutive multiples of 7 will be :-

• 7X → (7 x 11) = 77
• (7X + 7) → [(7 x 11)] + 7 = 84
• (7X + 14) → [(7 x 11)] + 14 = 91
• (7X + 21) → [(7 x 11)] + 21 = 98
• (7X + 28) → [(7 x 11)] + 28 = 105​

​Thus, 105 is the largest number in the series.

Hence, "105" is the correct answer.

Logic : Position value of each letter is written, then reversed.

So,

• SAVE is coded as :

​

Similarly,

• WEAK is coded as :

Hence, "111523" is the correct answer.

Logic : Sum of the position value of each letter is equal to 26.

So,

1) ATH

⇒ A(1) + T(20) + H(8) = 29

2. RFB

⇒ R(18) + F(6) + B(2) = 26

3. DMI

⇒ D(4) + M(13) + I(9) = 26

4. CGP

⇒ C(3) + G(7) + P(16) = 26

Thus, the sum of position value of each letter of ATH is 29, rest of them has sum value as 26.

Hence, "ATH" is the correct answer.

According to given figure:

The figure will appear when it is opened as follows:

Hence, "Option - (3)" is the correct answer.

The pattern followed here is : There are two patterns ;

• Consecutive even number is added in the position of value alternately starting with the first letter of each word.
• (3) is subtracted from the position of value alternately starting with the second letter of each word.

So,

• TUNER : VRRBX

​

Similarly,

• CLOCK : ?

​

Hence, "EISZQ" is the correct answer.

The logic followed here is : Each number is divided by (2).

Hence, "35" is the correct answer.

Refer to the diagram as shown below:

Here, the shaded area represents lemon fruits that are sour but NOT sweet.

Hence, 'option(1) - 45' is the correct answer.

The logic followed here is :-

From the given two different cubes the adjacent sides are as shown below :

⇒As 'e' is common on both the dice, it is clear that b, f, d and a are adjacent to it.

⇒Keeping 'e' constant and then rotating it in the clockwise direction, we get the faces opposite to each other.

Opposite pairs:

So, the opposite side of "a" will be side "f".

Hence, the correct answer is "f".

According to BODMAS rule:

*Given equation : 7 * 8 * 6 * 130 * 2 3

Now by the putting the signs:-

• Option - (1) : +, ÷, –, =, ×

​7 + 8 ÷ 6 - 130 = 2 × 3

7 + 1.33 - 130 = 2 × 3

7 + 1.33 - 130 = 6

8.33 - 130 = 6

-121.76 ≠ 6 (LHS ≠ RHS)

• Option - (2) : =, ×, +, ÷, –

​7 = 8 × 6 + 130 ÷ 2 - 3

7 = 8 × 6 + 65 - 3

7 = 48 + 65 - 3

7 = 113 - 3

7 ≠ 110 (LHS ≠ RHS)

• Option - (3) : ÷, ×, =, +, –

​7 ÷ 8 × 6 = 130 + 2 - 3

0.875 × 6 = 130 + 2 - 3

5.25 = 130 + 2 - 3

5.25 = 132 - 3

5.25 ≠ 129 (LHS ≠ RHS)

• Option - (4) : ×, +, =, ÷, –

​7 × 8 + 6 = 130 ÷ 2 - 3

7 × 8 + 6 = 65 - 3

56 + 6 = 62

62 = 62 (LHS = RHS)

Hence, "Option - (4)" is the correct answer.

The correct mirror image of the given combination when mirror is placed at PQ is as shown below:

Detailed Explanation:

• The line PQ is the mirror
• The word "FD8PCQ" the last letter is "F". So, the mirror image should be "

" ⇒ Option 1 is eliminated.

• The word "FD8PCQ" the last letter is "F". So, the mirror image should be "

" ⇒ Option 2 is eliminated..

• The word "FD8PCQ" the first letter is "Q". So, the mirror image should be "

" ⇒ Option 3 is eliminated.

Hence, the correct answer is "Option - (4)".

According to given conditions,

1) Jiva is the daughter of Kamal - Kamal is the parent of Jiva, so kamal can be either father or mother of Jiva.

2) Kamal has two sons - Kamal has two sons whose names are not known yet. So Kamal has three children.

3) Adah is the daughter of Manvita, who is the wife of Kamal’s son - As kamal has two sons, so Manvita is the wife of one of the son whose name is not knwon yet.

4) Prem is the brother of Ashok, who is the father of Adah - As Adah is the daughter of Manvita, therefore Ashok is the husband of Manvita. So, Ashok and Prem will be the first son and second son respectivelt as Prem is the brother of Ashok.

5) Veenu is Prem’s mother - As Veenu is the mother of Prem, therefore Kamal is the husband of Veenu.

Thus, according to the final family tree Veenu is the paternal grandmother of Adah, therefore Adah is the granddaughter of Veenu.

Hence, "Granddaughter" is the correct answer.

Logic : 

• (+1) is added to the position value of each first letter.
• (+2) is added to the position value of each second letter.
• (+3) is added to the position value of each third letter.

So,

Hence, "OUO" is the correct answer.

Given : Six friends, Neha, Kavya, Gita, Varun, Pooja and Kapil, have different ages.

Explanation : 

⇒As there are six friends so six positions have been arranged numbered from 1 to 6 from bottom to top as from youngest to the eldest. 

1) Three friends are older than Gita.

2) Pooja is older than only one friend.

3) Gita is older than Pooja but younger than Varun. 

4) The age of Kapil is between the ages of Varun and Kavya - After positioning Kapil and Kavya only one position is left which will be occupied by the only person left i.e Neha.

Thus, according to the final arrangement the order from youngest to the eldest will be ⇒ Neha, Pooja, Gita, Varun, Kapil and Kavya. Therefore Neha is the youngest one among them.

Hence, "Neha" is the correct answer.

According to the sequence in the dictionary:

2. Subscribe

• They all are facing towards the center.

Explanation :

1)F is sitting to the immediate left of A.

2) C is sitting between D and F.

3) B is sitting between A and E. 

Thus, according to the final arrangement D is sitting immediate right of E.

Hence, "D" is the correct answer.

Logic : The pattern followed here is column wise.

(Cube of first number) + (Cube of second number) = Third number

So,

• First column :

⇒$(7)^3$ + $(4)^3$ = 407

⇒343 + 64 = 407

⇒407 = 407 (LHS = RHS)

• Second column :

⇒$(8)^3$ + $(2)^3$ = 520

⇒512 + 8 = 520

⇒520 = 520 (LHS = RHS)

Similarly,

• Third row :

⇒$(9)^3$ + $(?)^3$ = 756

⇒729 + $(?)^3$ = 756

⇒$(?)^3$ = 756 - 729

⇒$(?)^3$ = 27

⇒? = 3

Hence, "3" is the correct answer.

Logic : (6) is added and subtracted alternately from the position value of each letter, starting with adding (+6) to the last letter of the word. Then reversed.

So,

• REFINE is coded as :

• Subtract Depreciation: NNP at MP = GNP at MP – Dep
• Subtract Net Indirect Taxes: NNP at FC = NNP at MP – NIT
• Measurement of National Income – Expenditure Method
• The expenditure method to measure national income can be understood by the equation given below: 
• Y = C + I + G + (X-M),
• where Y = GDP at MP, C = Private Sector’s Expenditure on final consumer goods, G = Govt’s expenditure on final consumer goods, I = Investment or Capital Formation, X = Exports, I = Imports, X-M = Net Exports

Given:

MP = Rs. 15000

Discount given = 18%

Desired final price = Rs. 10947 

Concept used:

SP = MP - MP × Discount%

Calculation:

Price after 1st discount = 15000 - 15000 × 18%

⇒ Rs. 12300

Addition discount = $\frac{12300-10947}{12300}$ × 100% = 11%

∴ An additional discount of 11% must be given to bring the net selling price to ₹10947.

Given:

A cylindrical pillar is 85 cm in diameter and 7 m in height.

Concept used:

Curved surface area of cylinder = 2πrh

Where, r = radius, h = height

Calculation:

Curved surface area of the cylindrical pillar

⇒ 2 × (22/7) × (85/200) × 7    [1 m = 100 cm]

⇒ 18.7 m²

Required cost = 18.7 × 20 = ₹374

∴ The cost of painting the curved surface of the pillar at the rate of ₹20 per m2 is ₹374.

Shortcut Trick

According to the question,

10% of MP = ₹1000

⇒ Purchased Price = 80% of MP = ₹8000

Alternate Method

Given:

Actual discount = 20%

Concept used:

Purchased Price = MP × (100 - discount)%

Calculation:

Let the marked price of the sofa be 100x

Actual purchase price = 100x × (100 - 20)% = 80x

Purchase price at 30% discount = 100x × (100 - 30)% = 70x

According to the question,

80x - 70x = 1000

⇒ 10x = 1000

⇒ x = 100

So, actual purchase price of the sofa = 80 × 100 = 8000

∴ She paid ₹8,000 for the sofa.

Shortcut Trick

According to the question,

5% of CP = ₹80

⇒ CP = 100% = ₹1600

∴ The cost price of the chair is ₹1600.

Alternate Method

Given:

Profit % = 10

Concept used:

SP = CP × (100 + Profit)%

Calculation:

Let the CP of the chair be 100x

Actual SP = 100x × (100 + 10)% = 110x

SP at 15% profit = 100x × (100 + 15)% = 115x

According to the question,

115x - 110x = 80

⇒ 5x = 80

⇒ x = 16

CP = 100 × 16 = 1600

∴ The cost price of the chair is ₹1600.

Given:

A train going at 1/2 of its usual speed takes 60 minutes more to reach its destination.

Concept used:

Speed is inversely proportional to time.

Calculation:

Let the speed of the train be 2x

⇒ Reduced speed = 2x × 1/2 = x

Ratio of speed of the train before and after = 2x : x

Time ratio of the train before and after = x : 2x

According to the question,

2x – x = 60 min

⇒ x = 60 min or 1hr

So, its usual time = 1 hour

∴ Its usual time to cover the same distance is 1 hour.

Given:

60% of the students are boys and the rest are girls.

40% of the boys and 70% of the girls pass a test

The number of girls who failed is 42

Calculation:

Let the total number of students be 100x

⇒ Boys = 100x × 60% = 60x

Girls = 100x - 60x = 40x

According to the question,

40x × 30% = 42

⇒ 12x = 42

⇒ x = 3.5

Number of boys = 60 × 3.5 = 210

Number of boys who failed = 210 × 60% = 126

∴ The number of boys who failed is 126.

Shortcut Trick

We can calculate CI by the tree method

CI = (3 × 7280) + (3 × 728) + 72.8 = 24096.80

∴ The required compound interest is ₹ 24096.80.

Alternate Method

Given:

Principal amount (P) = ₹72,800

Number of years (T) = 3

Rate of interest (R) = 10%

Formula used:

Total amount (A) = P × (1 + (R/100))^T

C.I = Total amount – Principal amount

Calculation:

A = 72800(1 + 10/100)³

⇒ A = 72800(1 + 1/10)3

⇒ A = 72800(11/10)3

⇒ A = 72800 × 1331/1000

⇒ A = 96896.8

C.I = 96896.8 – 72800 = 24096.80

∴ The required compound interest is ₹ 24096.80.

Given:

A man distributed ₹45,000 and ₹18,000 among his sons A, B, and C.

The first amount was distributed in the ratio 3 : 7 : 5

The second amount was distributed in the ration 4 : 2 : 3

Calculation:

In ₹45,000:

Share of A = 45000 × 3/15 = 9000

Share of C = 45000 × 5/15 = 15000

In ₹18,000:

Share of A = 18000 × 4/9 = 8000

Share of C = 18000 × 3/9 = 6000

Total amount received by A = 9000 + 8000 = 17000

Total amount received by C = 15000 + 6000 = 21000

Difference = 21000 - 17000 = 4000

∴ The difference between the shares of A and C is ₹4,000.

Given:

One side of a right-angled triangle is thrice the other.

The hypotenuse is 8 cm

Concept used:

Area of a right angle triangle = (1/2) × p × b

Where, p = perpendicular, b = base

Calculation:

Let the sides be 3x cm and x cm

⇒ 3x² + x² = 8²

⇒ 9x2 + x2 = 64

⇒ 10x2 = 64

⇒ x2 = 64/10

Area of the triangle = (1/2) × 3x × x

⇒ (1/2) × 3x²

⇒ (1/2) × 3 × 64/10

⇒ 96/10 = 9.6 cm²

∴ The area of the triangle is 9.6 cm2.

Given:

A, B, and C contested an election and received 1800, 3300, and 3900 votes respectively

Required % = (3300/9000) × 100

⇒ 36.66 ≈ 36.67%

∴ B got 36.67% of the total votes.

Given:

John can complete the work in 6 days working 8 hours each day

Manu can complete the work in 3 days working 4 hours each day

Concept used:

Total Work = Efficiency × Time

Calculation:

Let the efficiency of John be x units/hour

⇒ Total work = 6 × 8x = 48x

Efficiency of Manu = 48x/(3 × 4) = 4x

Effective efficiency = x + 4x  = 5x

Time = ($\rm \frac{48x}{\frac{48}{5}×5x}$) = $\frac{48x}{48x}$ = 1 day

∴ The required time is 1 day.

Given:

Numbers = 415, 688, 825

Remainders = 7, 8 and 9

Concept used:

Required Number = HCF of the divisible numbers

Calculation:

Numbers which are fully divisible

⇒ 415 - 7 = 408

⇒ 668 - 8 = 680

⇒ 825 - 9 = 816

Calculating HCF

408 = 2³ × 3 × 17

680 = 2³ × 5 × 17

816 = 2⁴ × 3 × 17

⇒ HCF = 2³ × 17 = 8 × 17 = 136

∴ The required answer is 136.

Given:

The ratio of monthly income to the expenditure is 14 : 11

Shortcut Trick

Applying successive formula

A × $\frac{125}{100}$ × $\frac{120}{100}$ × $\frac{55}{100}$ = 330

⇒ A = 400

⇒ CP for B = 400 × $\frac{125}{100}$ = ₹500

∴ B bought the article for ₹500.

Alternate Method

Given:

A sold an article to B at 25% profit

B sold it to C at 20% profit

C sold is to D at 45 % loss

Concept used:

1. SP = CP × (100 + Profit)%

2. SP = CP × (100 - Loss)%

Calculation:

Let the cost price of the article to A be 100x

SP of A = 100x × (100 + 25)%

⇒ 100x × 125% = 125x

CP of B = 125x

⇒ SP of B = 125x × (100 + 20)% = 150x

CP of C = 150x

SP of C = 150x × (100 - 45)% = 82.5x

CP of D = 82.5x

⇒ 82.5x = 330

⇒ x = 330/82.5 = 4

CP of B = 125 × 4 = 500

∴ B bought the article for ₹500.

Calculation:

Sum of age of five person = 28 × 5 = 140 

Sum of age of four numbers = 26 × 4 = 104 

Age of excluded person = 140 – 104 = 36 

∴ The age of the excluded person is 36 years.

Additional Information

After excluding a value, if the average increases

Excluded = Old Avg + (Increase in Avg) × New no. of terms

Given:

A box contains 25p and 10p in the ratio 6 : 5

Total amount = ₹226

Calculation:

Let the number of 25p and 10p coins be 6x and 5x

⇒ 25 × 6x + 10 × 5x = 226 × 100     [As ₹1 = 100p]

⇒ 150x + 50x = 22600

⇒ 200x = 22600

⇒ x = 113

Number of 10p coins = 113 × 5 = 565

∴ The number of 10p coins is 565.

Given:

A train covers a distance of 325 km in $2\frac{1}{2}$ hours with a uniform speed.

Concept used:

Speed = Distance/Time

Calculation:

Speed = $\frac{325}{\frac{5}{2}}$      ($2\frac{1}{2}$ = $\frac{5}{2}$ hours)

⇒ Speed = 65 × 2 = 130 km/h

Required time = 650/130 = 5 hours

∴ The time taken to cover a distance of 650 km at the same speed is 5 hours.

Given:

The ratio of four positive numbers is 5 : 8 : 12 : 18

LCM of the numbers is 2880

Calculation:

Let the numbers be 5x, 8x, 12x and 18x

LCM of 5x, 8x, 12x and 18x = 360x

According to the question,

360x = 2880

⇒ x = 2880/360 = 8

Difference between the greatest and the smallest number

⇒ (18 × 8) - (5 × 8)

⇒ 8 (18 - 5) = 104

∴ The difference between the greater and the small number is 104.
