And,

Mercury is planet.

The correct Venn diagram is,

Hence, option 4 is the correct answer.

By interchanging the given numbers and using BODMAS rule,

Option 1 → 1 and 9

5 × 2 + 8 ÷ 2 – 9 = 1 – 6 ÷ 3 + 6 × 3

5 × 2 + 4 – 9 = 1 – 2 + 6 × 3

10 + 4 – 9 = 1 – 2 + 18

14 – 9 = 19 – 2

5 ≠ 17

Option 2 → 5 and 9

9 × 2 + 8 ÷ 2 – 1 = 5 – 6 ÷ 3 + 6 × 3

9 × 2 + 4 – 1 = 5 – 2 + 6 × 3

18 + 4 – 1 = 5 – 2 + 18

22 – 1 = 23 – 2

21 = 21

Option 3 → 8 and 9

5 × 2 + 9 ÷ 2 – 1 = 8 – 6 ÷ 3 + 6 × 3

5 × 2 + 4.5 – 1 = 8 – 2 + 6 × 3

10 + 4.5 – 1 = 8 – 2 + 18

14.5 – 1 = 26 – 2

13.5 ≠ 24

Option 4→ 2 and 6

15 × 6 + 8 ÷ 6 – 1 = 9 – 2 ÷ 3 + 2 × 3

5 × 6 + 1.3 – 1 = 9 – 0.6 + 2 × 3

30 + 1.3 – 1 = 9 – 0.6 + 6

31.3 – 1 = 15 – 0.6

30.3 ≠ 14.4

Hence, option 2 is the correct answer.

The mirror image when mirror is placed on the line AB is,

In mirror the left side of object becomes the right side, similar phenomenon can be seen in the above image.

The figure which is embedded in the given figure is,

Hence, option 1 is the correct answer.

By decoding given information:

After decoding,

13 × 3 – 15 ÷ 3 + 5

= 13 × 3 – 5 + 5

= 39 – 5 + 5

= 44 – 5

= 39

Hence, “39” is the correct answer.

Conclusion 1: Government understands that the condition of poor farmers’ needs immediate attention → follows, as it is mentioned that annual pension will be given to farmers.

Conclusion 2: No benefits are announced for other sections of society → not follow, as no such information is given in the statement.

Only conclusion 1 follows.

Hence, option 1 is the correct answer.

In the given series, the arm with flag symbol is changing its position in anti-clockwise with one gap and then 2 gaps alternatively.

Therefore, the complete pattern will be,

Hence, option 4 is the correct answer.

The pattern followed here is,

First number

Second number = first number + 5

Third number = first number + 20

Like

73

73 + 5 = 78

73 + 20 = 93 → (73, 78, 93)

Similarly,

Option 1 → (67, 72, 82)

67

67 + 5 = 72 = 72

67 + 20 = 87 ≠ 82

Option 2 → (23, 33, 38)

23

23 + 5 = 28 ≠ 33

23 + 20 = 53 ≠ 38

Option 3 → (29, 34, 39)

29

29 + 5 = 34 = 34

29 + 20 = 49 ≠ 39

Option 4 → (145, 150, 165)

145

145 + 5 = 150 = 150

145 + 20 = 165 = 165

Hence, option 4 is the correct answer.

The mirror image when mirror is placed on the line AB is,

Hence, option 1 is the correct answer.

First comes Meter.

Meter is followed by Method.

Method is followed by Meticulous.

Meticulous is followed by Metric.

Metric is followed by Mettle.

The correct dictionary order is,

5. Meter → 3) Method → 1) Meticulous → 2) Metric → 4) Mettle

Hence, option 2 is the correct answer.

The pattern followed here is,

102 = (9 + 1)²+ 2 = (10)²+ 2 = 100 + 2 = 102

146 = (11 + 1)² + 2 = (12)²+ 2 = 144 + 2 = 146

Similarly,

? = (13 + 1)² + 2 = (14)²+ 2 = 196 + 2 = 198

Hence, ‘198’ is the correct answer.

The figure which is embedded in the given figure is,

Pianists are 2, 7, 4 and 5

Guitarists are 1, 1, 5, 7 and 20

Drummers are 1, 1, 4, 8 and 7

So, the answer will be common in singers, pianists, and guitarists but it should not be a drummer which is 5.

Hence, 5 is the correct answer.

The pattern followed here is,

Hence, M is the correct answer.

When the given cube is folded,

Hence, option 2 is the correct answer.

The figure obtained after paper is unfolded is,

Hence, option 4 is the correct answer.

Option 1 (17 and 3, – and ÷)

Given equation: 17 × 15 + 3 – 11 ÷ 3 = 45

After interchanging:3 × 15 + 17 ÷ 11 – 3 = 45

Solving using BODMAS

3 × 15 + 1.54 – 3

45 + 1.54 – 3

46.54 – 3

 43.54 ≠ 45

Option 2 (15 and 11, + and –)

Given equation: 17 × 15 + 3 – 11 ÷ 3 = 45

After interchanging: 17 × 11 – 3 + 15 ÷ 3 = 45

Solving using BODMAS

17 × 11 – 3 + 5

187 – 3 + 5

192 – 3

189 ≠ 45

Option 3 (15 and 11, – and ×)

Given equation: 17 × 15 + 3 – 11 ÷ 3 = 45

After interchanging: 17 – 11 + 3 × 15 ÷ 3 = 45

17 – 11 + 3 × 5

17 – 11 + 15

32 – 11

21 ≠ 45

Option 4 (15 and 11, + and ×)

Given equation: 17 × 15 + 3 – 11 ÷ 3 = 45

After interchanging: 17 + 11 × 3 – 15 ÷ 3 = 45

17 + 11 × 3 – 15 ÷ 3

17 + 11 × 3 – 5

17 + 33 – 5

50 – 5

45 = 45

Hence, option 4 is the correct answer.

103, 113, 107 are prime number that is they are divisible 1 and the number themselves except 117.

Hence, “117” is the odd one out.

The pattern followed here is,

In 2^nd step only middle element gent inverted all other are same. 

In 3^rd step all corner images are rotating in anticlockwise direction and middle element is same. 

Again in 4^th step only middle element get inverted others are same.

So,

In 5^th step which is missing all corner element get rotated in anticlockwise direction and middle element is same.  

Therefore, the pattern the next figure in the series is,

The complete series is as follows,

Hence, option 1 is the correct answer.

The pattern followed here is that oval shape is rotating in clock wise direction and in second figure and other corresponding figures new element replaces the existing ones.

Like in second figure ‘oval with dot’ replaces ‘oval’.

In third ‘rectangle’ is replaced by ‘+’ symbol.

In fourth ‘triangle’ is replaced by ‘S’.

The only figure with correct position of oval with dot is 3^rd and 4^th.

The replacement in figures is also in pattern if we number all figures in first figure of series as

1 → ‘oval’

2 → ‘rectangle’

3 → ‘triangle’

4 → ‘×’

1, 2 and 3 are replaced already, the left one to be replaced is ‘×’.

In fifth the turn to replace is of ‘×’.

But 3^rd figure consist of ‘×’, so 4^th figure is the next figure in the series.

The figure next in the series will be,

The complete series will be this,

Hence, option 4 is the correct answer.

The pattern followed here is,

Square root of 1^st term + square root of 2^nd term = third term

√81 + √9 = 9 + 3 = 12 ≠ 19

√64 + √100 = 8 + 10 = 18 = 18

√25 + √36 = 5 + 6 = 11 = 11

√16 + √64 = 4 + 8 = 12 = 12

Hence, “81 : 9 : 19” is the odd one out.

The number of triangles in the given figure are,

Hence, “33 ” is the correct answer.

Drawing diagram according to the following information,

Distance between break down location and location at the beginning = AB = √3² + 4² = √9 + 16

= √25 = 5

Hence, “5 km” is the correct answer.

The pattern followed here is,

Hence, 155 is the correct answer.

A is the starting point and B is the end point.

AB = 70m – 30m

AB = 40m

So stayen is 40m away from his starting point in North direction.

Hence, option 2 is the correct answer.

The pattern followed here is,

Second number = (first number × 2) + (1/4^th of first number)

Like 76 : 171

171 = (76 × 2) + (1/4^th of 76)

171 = 152 + 19

171 = 171

Similarly,

28 : 63 → 63 = (28 × 2) + (1/4^th of 28) = 56 + 7 = 63 = 63

62 : 135 → 135 = (62 × 2) + (1/4^th of 62) = 124 + 15.5 = 139.5 ≠ 135

24 : 39 → 39 = (24 × 2) + (1/4^th of 24) = 48 + 6 = 54 ≠ 39

52 : 115 → 115 = (52 × 2) + (1/4^th of 52) = 104 + 13 = 117 ≠ 115

“28 : 63“share the same relationship as that shared by the given pair of numbers.

Hence, “28 : 63” is the correct answer.

The highest unit of measurement among the given units is Hectometre

After that comes Decametre,

After Decametre it is Decimetre,

After Decimetre it is Centimetre,

And the smallest is Millimetre.

3.Hectometre →1.Decametre → 5.Decimetre → 4.Centimetre →2.Millimetre

Hence, option 2 is the correct answer.

The pattern followed here is,

Column 1 (top to bottom) → (number in first box + number in second box) × 2 = number in third box

Like,

(3 + 14) × 2 = 34

(18 + 13) × 2 = 62

Similarly,

(27 + ?) × 2 = 98

27 × 2 + 2 × ? = 98

2 × ? = 98 – 54

2 × ? = 44

? = 44 ÷ 2 = 22

Hence, ‘22’ is the correct answer.

The pattern followed here is,

Second number/fourth number = first digit of first/third number × second digit of first/third number

Like

3 × 1 = 3

7 × 5 = 35

Similarly,

Sixth number = first digit of fifth number × second digit of fifth number

5 × 4 = 20

Hence, ‘20’ is the correct answer.

From the question, code for R, I, V and E is as follows,

R → 10

I → 3

V → 5

E → 2

And coding the vowels a, e, i, o and u as follows,

A → 1

E → 2

I → 3

O → 4

U → 5

From the above information best possible code for ‘PETROL’ is as follows,

P →

E → 2

T →

R → 10

O → 4

L →

Similar code can only be seen in option 3.

Hence, option 3 is the correct answer.

The pattern followed here is,

Sum of place value of alphabets in word × 3 = Code Number

Like for D, Sum of place value of alphabet in word = 4, 4 × 3 = 12 therefore D = 12

And for AGE,

Place value of A = 1, G = 7 and E = 5.

Sum of place value of alphabet in word = 1 + 7 + 5 = 13, 13 × 3 = 39, therefore AGE = 39

Similarly,

For JADE

Place value of J = 10, A = 1, D = 4 and E = 5.

Sum of place value of alphabet in word = 10 + 1 + 4 + 5 = 20, 20 × 3 = 60, therefore JADE = 60.

Hence, “60” is the correct answer.

The pattern followed here is,

For every single alphabet there are two alphabet in code language which are one preceding alphabet and one succeeding alphabet of that alphabet.

For B code is one alphabet preceding to B that is ‘A’ and one succeeding alphabet to B that is ‘C’ so the code for B is ‘AC’

B → ABC

R → QRS

I → HIJ

D → CDE

G → FGH

E → DEF

So Code for BRIDGE is ACQRHJCEFHDF.

Similarly,

P → OPQ

O → NOP

W → VWX

E → DEF

R → QRS

So code for POWER is OQNPVXDFQS.

Hence, ‘OQNPVXDFQS’ is the correct answer.

The best possible Venn diagram is as follows,

Conclusions I: Some Americans are Singaporeans → False (This is definitely false)

Conclusions II: All Singaporeans are Delhites → False (This is possible but not definite)

AsNeither conclusion I nor II follows.

Hence, option 3 is the correct answer.

The pattern followed here is

104 + 4 = 108

108 ÷ 2 = 54

54 + 4 = 58

58 ÷ 2 = 29

29 + 4 = 33 ≠ 31

Hence, “31” does not belong to the series.

Opposite of ‘Generous’ is ‘Greedy’.

Similarly,

Opposite of ‘Vindictive’ is ‘Merciful’.

Hence, “Merciful” is the correct answer.

The pattern followed here is,

Hence, “Rial : Currency” is the correct answer.

As spokes are found in wheel which are connecting roads connecting the centre of wheel to its outer edge so, Wheel : Spoke

Similarly,

Rooms are found in house.

House : Room share the same relationship as that shared by the given pair of words.

Hence, “House: Room” is the correct answer.

The pattern followed here is,

Addition of the given two number is multiple of 19.

1. 50 – 7 → 57, 19 × 3 = 57

2) 64 – 32 → 96, Not divisible by 19.

3. 16 – 3 → 19, 19 × 1 = 19

4. 51 – 25 → 76, 19 × 4 = 76

All except, ‘64 - 32’ follow the same pattern.

Hence, “64 - 32” is different from others.

2^nd Method

All are co-prime with each other except 64 - 32.

Hence 64 - 32 is different from others.

The pattern followed here is,

The place value of T is 20, 20^th letter from the reverse is G.

The place value of S is 19, 19^th letter from the reverse is H.

The place value of R is 18, 18^th letter from the reverse is I.

The place value of A is 1, 1^st letter from the reverse is Z.

Therefore, TSRA – ZIHG

Similarly, 

Therefore, ARNI – RMIZ.

Therefore, OLEV - EVOL

The pattern is followed in above three except, XHEP - KVRA

The place value of X is 24, 24^th letter from the reverse is C.

The place value of H is 8, 8^th letter from the reverse is S.

The place value of E is 5, 5^th letter from the reverse is V.

According to the question

(2x + 3y + 4)(2x + 3y - 5) = (ax² + by² + 2hxy + 2gx + 2fy + c)

4x² + 6xy - 10x + 6xy + 9y² - 15y + 8x + 12y - 20 = (ax² + by² + 2hxy + 2gx + 2fy + c)

4x² + 12xy - 2x + 9y² - 3y - 20 = (ax² + by² + 2hxy + 2gx + 2fy + c)

On comparing

a = 4, h = 6, g = -1, b = 9, f = -3/2 and c = -20

Now,

{(g + f - c)/abh}

{(-1 - 3/2 + 20)/4 × 9 × 6}

{(-2 - 3 + 40)/2}/(4 × 6 × 9)

CP of the article = 300

SP of the article = 300 × (105/100) = 315

MP of the article = 315 × (100/90) = 350

Calculation:

3 hr 20 min = 3 + 20/60 = 3 + 1/3 = 10/3

Total distance = 30 km.

5/6^th of the distance = 30 × (5/6) = 25 km

Speed of the person = 25/(10/3) = 7.5 km/hr

∴ Speed is 7.5 km/hr

Total work = 120 unit

The tank will fill if all three pipes open together = 120/(20 + 15 - 12) = 120/23 = \(5\frac{5}{{23}};hrs\)

As we know,

Simple Interest = PRT/100

Let total sum be Rs. x, then

Remaining part = x - x/8 - 3x/5 = (40x - 5x - 24x)/40 = 11x/40

According to the question

(x × 1/8 × 5 × 2)/100 + (x × 3/5 × 6 × 2)/100 + (x × 11/40 × 10 × 2)/100 = 1674

5x/400 + 36x/500 + 11x/200 = 1674

(25x + 144x + 110x)/2000 = 1674

279x/2000 = 1674

x = 1674 × 2000/279

x = 12000

Alternate Solution:

Let total number be 40x, then

As we know,

40x × 1/8 = 5x and 40x × 3/5 = 24x and 40x - 5x - 24x = 11x

According to the question

[2 × (5x × 5 + 24x × 6 + 11x × 10)]/100 = 1674

2 × 279x = 167400

558x = 167400

x = 167400/558

x = 300

Total sum = 40 × 300 = 12000

Capitals ratio of A, B and C = 2/3 : 3/5 : 5/6 = (2 × 30) /3 : (3 × 30) /5 : (5 × 30) /6 = 20 : 18 : 25

Capitals ratio of A, B and C after end of the year,

(20 × 8 + 20 × 5/4 × 4) : 18 × 12 : 25 × 12 = (160 + 100) : 216 : 300 = 260 : 216 : 300

Capitals ratio of A, B and C after end of the year = 260x : 216x : 300x = 65x : 54x : 75x

According to the question

65x + 54x + 75x = 5820

194x = 5820

x = 5820/194 = 30

Share of C = 75 × 30 = Rs. 2250

Total runs in 50 overs = 282

Average of runs in 20 overs = 4.5

Sum of run in 20 overs = 4.5 × 20 = 90

Runs need in remaining 30 overs = 282 - 90 = 192

Average runs in 30 overs = 192/30 = 6.4

Let marked price of the article be Rs. x, then

According to the question

x × (90/100) × (95/100) × (96/100) = 98496

x = 98496 × (100/90) × (100/95) × (100/96)

x = 1,20,000
