But according to question figure D is:

Alternate logic:

In all the figures, the circle is at the end of the line except for figure 4, where the circle is in the middle of the line.

Hence, option (4) is the correct answer.

The logic follows here is;

LOGIC: (First Number + Second Number)/2 = Third Number

1) 13, 15 : 14

(13 + 15)/2

= 28/2

= 14

2) 6, 8 : 7

(6 + 8)/2

= 14/2

= 7

3) 14, 16 : 18

(14 + 16)/2

= 30/2

= 15 ≠ 18

4) 12, 16 : 14

(12 + 16)/2

= 28/2

= 14

Hence, "14, 16 : 18" is the correct answer.

The embedded part of this image is:

Hence, Option (4) is the correct answer.

At present;

x : y = 1 : 2

Suppose age of x = p

And age of y = 2p

Five years hence;

Age of x = (p + 5)

Age of y = (2p + 5)

According to question;

(p + 5) : (2p + 5) = 2 : 3

3 × (p + 5) = 2 × (2p + 5)

3p + 15 = 4p + 10

p = 5

So, present age of x = 5 years 

Hence, "5 years" is the correct answer.

To strike 6 times, the clock goes 6 bongs.

bong-bong-bong-bong-bong-bong

Notice that there are only 5 dashes between those 6 bongs.

Therefore, there are only 5-time intervals between the 6 bongs.

So we divide 6 seconds by 5 and get each time interval between bongs

as $6 \over 5$

To strike 10 times, the clock goes:

bong-bong-bong-bong-bong-bong-bong-bong-bong-bong

Notice that there are only 9 dashes between those 10 bongs.

Therefore, there are only 9-time intervals between the 10 bongs.

Since each time interval = $6 \over 5$ seconds

9 of those time intervals between bongs is 9 × $6 \over 5$ = $54\over 5$

= $10\frac{4}{5}$

Hence, option (3) is the correct answer.

The pattern follows here is;

In Step 1:

One dot in a small circle is increased and one dot in the bigger circle is decreased.

So, In the second image there two dots in smaller circle and 4 dots in bigger circle.

In Step 2:

So, In the third image there three dots in a smaller circle and 3 dots in a bigger circle.

In Step 3: 

One dot in a small circle is increased and one dot in the bigger circle is decreased.

Similarly, In the fourth image there for dots in a smaller circle and 2 dots in a bigger circle.

Hence, option (4) is correct.

The pattern follows here is;

In each figure one circle is blank and one is lines.

But in figure C both the circles are blank.

So, this figure C is different from all other figures.

Hence, option (4) is correct.

= (20 × 23428)/100

= 23428/5

= 4685.6 tonnes

Hence, "4685.6 tonnes" is the correct answer.

Given:

The radius(r) of the solid cylinder = 8 cm

The height(h) of the solid cylinder = 10 cm

The radius(R) of the cone = 20 cm

Formula used:

Volume of the solid cylinder = πr2 h

Where, r = Radius of the solid cylinder, h = height of the solid cylinder

Volume of the cone = 1/3 × πR2H

Where, R and H are the radii and the height of the cone respectively.

Calculation:

According to the question:

Volume of the solid cylinder = Volume of the cone

⇒ πr2 h = 1/3 × πR2H

⇒ (8)² × 10 = 1/3 × (20)² × H

⇒ H = (64 × 10 × 3)/400 

⇒ H = 4.8 cm

∴ The height of the cone is 4.8 cm.

Given:

Total principal = Rs. 10000

Rate = 6% and 4%

Time = 2 years

Formula Used:

S.I = PRT/100

Where,

S.I = Simple interest, P = Principal,

R = Rate of interest, T = Time duration

Calculation:

Let the principal at the rate of 6% and 4% be x and (10000 - x) respectively,

According to the question, we have

(x × 6 × 2)/100 = {(10000 - x) × 4 × 2}/100 

⇒ 12x = 80000 - 8x

⇒ 20x = 80000

⇒ x = 4000

∴ The principal at the rate of 6% is Rs. 4000.

Given:

In first case:

Speed(S₁) = 75 km/hr

Distance(D₁) = 30 km

In second case:

Speed(S₂) = 60 km/hr

Distance(D₂) = 50 km

Formula:

Average Speed = (Total Distance/Total Time)

Time = Distance/Speed

Calculation:

Total Distance = 30 + 50 = 80 km

According to the question:

In first case:

Time = $\frac{{30}}{75}$ = $\frac{{2}}{5}$ hrs

In second case,

Time = $\frac{{50}}{60}$ = $\frac{{5}}{6}$ hrs

Total Time = $\frac{{2}}{5}$ + $\frac{{5}}{6}$ = $\frac{{12 + 25}}{30}$ = $\frac{{37}}{30}$ hrs

Average Speed = (Total Distance/Total Time)

Average Speed = 80 × $\frac{{30}}{37}$ = 64.86 = 64.9 km/hr (approx.)

∴ The average speed of whole journey is 64.9 km/hr.

Given:

Cost price = Rs. 580 + Rs. 120 = Rs. 700

Discount% = 20%

Profit% = 28%

Formula used:

S.P = $\frac{{(100 + P\%)}}{100}\times C.P$

S.P = $\frac{{(100 - D\%)}}{100}\times M.P$

Where, M.P = Market Price, S.P = Selling Price, C.P = Cost Price

Calculation:

According to the question:

Profit% = 28%

S.P = $\frac{{(100 + 28\%)}}{100}\times 700$

⇒ S.P = $\frac{{128}}{100}\times 700$ = Rs. 896

Now,

S.P = $\frac{{(100 - D\%)}}{100}\times M.P$

⇒ 896 = $\frac{{(100 - 20\%)}}{100}\times M.P$

⇒ M.P = $\frac{{896}}{4}\times 5$ = Rs. 1120

∴ The marked price is Rs. 1120.

Given:

Time taken to complete the whole work by A and B = 36 hours

Time taken to complete the whole work by B and C = 45 hours

Time taken to complete the whole work by C and A = 60 hours

Concept used:

Efficiency = Work done/Time taken

Calculation:

Let the total work be LCM of 36, 45, 60  i.e. 180 units.

Let the efficiency of A, B and C be a, b and c respectively.

Efficiency of A and B together,

⇒ a + b = 180/36 = 5 units/hours     ----(1)

Efficiency of B and C together,

⇒ b + c = 180/45 = 4 units/hours     ----(2)

Efficiency of C and A together,

⇒ c + a = 180/60 = 3 units/hours    ----(3)

Adding equation (1), (2) and (3), we get,

⇒ (a + b) + (b + c) + (c + a) = 5 + 4 + 3

⇒ 2a + 2b + 2c = 12

⇒ a + b + c = 12/2 = 6 units/hours

⇒ b = 6 - (a + c)

⇒ b = 6 - 3

⇒ b = 3

Time taken by B to complete the whole work alone = 180/3 = 60 hours

B complete the 60% of the work = 60 × 60/100 = 36 hours

∴ B complete the 60% of the work in 36 hours.

Given:

On selling 35 articles gain is equal to selling price 5 articles.

Formula Used:

Gain = SP – CP

Gain percent = $\frac{{Gain}}{CP}\times 100$

Where, CP = Cost Price

Calculation:

According to the question,

⇒ Selling price of 35 articles = Cost price of 35 articles + Selling price of 5 articles

⇒ 35SP = 35CP + 5SP

⇒ 35SP - 5SP = 35CP

⇒ 30SP = 35CP

⇒ SP/CP = 7/6

Let Selling price be Rs. 7x

And cost price be Rs. 6x

SP = 7x and CP = 6x

Gain = SP – CP

⇒ Gain = 7x – 6x = x

Gain percent = $\frac{{Gain}}{CP}\times 100$

⇒ Gain percent = x/6x × 100

⇒ Gain percent = 50/3%

∴ His percent gain is $\frac{{50}}{3}$%.

Given:

Pipe A can fill a tank in 8 hours 

Pipe B can fill a tank in 12 hours 

Pipe C alone can empty the full tank in 15 hours.

A and B are opened together for 2 hours and then C is also opened

Formula used:

Time taken by A + B + C = Remaining work/Efficiecy.(A + B + C)

Calculation:

According to the question;

A + B = 25 w/hrs

They work for 2 hours,

Toatal work done = 25 × 2 = 50 units

Remaining work = 120 - 50 = 70 units

Now, A is closed and B and C work,

B + C = 10 + (-8) = 2 w/hrs

Time Taken = 70/2 = 35 hours

Total Time Taken to fill the tank = 35 + 2 = 37 hrs.

∴ Total Time Taken to fill the tank is 37 hrs.

Given:

Ratio of spirit and water in A = 2 : 3

Ratio of spirit and water in B = 4 : 5

Calculations:

Spirit of contain A = 2/5

And spirit of contain B = 4/9

Let mixture be t.

Alligation method,

According to the Question,

(4/9 -t)/(t - 2/5) = 5/7

⇒ 7(4 - 9t)/9(5t - 2) = 1

⇒ 28 - 63t = 45t -18

⇒ 46 = 108t

⇒ t = 46/108 

Now, Spirit/Total = 46/108

So, water = 108 - 46 = 62

Required ratio = Spirit/Water = 46/62 = 23 : 31

∴  The ratio of spirit and water in the new mixture is 23 : 31.

Additional Information

Given:

Total girls % in a class = 60%

Total boys %  in a class = 40%

Total boys passed in the test = 60%

Total girls passed in the test = 70%

Calculation:

Let the total no. of students be x

According to the question:

Total girls in a class = x × $\frac{{60}}{100}$ = $\frac{{3x}}{5}$ 

Total boys in a class = x × $\frac{{40}}{100}$ = $\frac{{2x}}{5}$

Passed Girls = $\frac{{3x}}{5}$ × $\frac{{70}}{100}$= $\frac{{21x}}{50}$

Passed Boys = $\frac{{2x}}{5}$ × $\frac{{60}}{100}$ = $\frac{{6x}}{25}$

Total passed students = $\frac{{21x}}{50}$ + $\frac{{6x}}{25}$

⇒ $\frac{{21x + 12x}}{50}$= $\frac{{33x}}{50}$

Now,

Total passed% = $\frac{{33x}}{50 \times x} \times 100$ = 66%

∴ Total passed % students are 66%.

Given:

Calculations:

The least number which will be completely divisible by the 21, 28, 36, and 45 will be the LCM of 21, 28, 36, and 45

⇒ LCM(21, 28, 36, 45) = 1260

The least number will be completely divisible by the 21, 28, 36, and 45 and leaves remainder 4 = 1260k + 4

Where,

k = natural number

when k = 1

⇒ 1265

Here 1265 is not divisible by 13.

When k = 1, 2, 3, 4, 5. The number is not divisible by 13.

Now, k = 4

Number = 1260 × 4 + 4

⇒ Number = 5044

The number 5044 is divisible by 13

Given:

Sides of a triangle = 26 m, 28 m and 30 m

Formula used:

Area of a triangle = $√{s(s \ - \ a)(s \ - \ b)(s \ - \ c)}$

Semiperimeter(s) = $\dfrac{a \ + \ b \ + \ c}{2}$

Calculation:

The semiperimeter of the triangle is

$\dfrac{30 \ + \ 28 \ + \ 26}{2}$ = 42 m

Area of the triangle

= $\sqrt{42(42 \ - \ 30)(42 \ - \ 28)(42 \ - \ 26)}$

⇒ $\sqrt{42\ × \ 12\ × \ 14\ × 16}$ = √112896 = 336 m²

The price of levelling is

336 × 15 = Rs. 5040

∴ The cost of levelling the plot is Rs. 5040.
