= {15 - 8} × 2

= 7 × 2 = 14

Similarly,

Figure 2: {(5 × 6) - (4 × 7)} × 2

= {30 - 28} × 2

= 2 × 2 = 4

Hence, ‘4’ is the correct answer.

Given:

Total strength of students = 45

Rank of a boy = 20^th from one end.

∴ Rank from another end will be 45 - 20 + 1 = 26^th

According to question:

Two boys joined, then total strength now = 47

Then, the rank dropped by one. This means one boy is ahead of him and another one is in behind.

His new rank from the end will be 26^th + 1 = 27^th

Hence, the rank of the boy is 27^th.

If rank from one side is given, then rank from another side will be:

Total strength - given rank + 1

EXPLANATION:

• When a particle is revolving in a circular path,  the centripetal force acts on the particle towards the center of the circular path and is represented by

​$\Rightarrow F_c=\frac{mv^2}{r}$

​Where F is the centripetal force, m is the mass of the particle, v is velocity, and r is the radius.

Additional Information

• Centripetal acceleration: The acceleration is directed radially toward the center of the circle and has a magnitude equal to the square of the body's velocity along the curve divided by the radius of the circular path.

$\Rightarrow a_c=\frac{V^2}{r}$

Where a is centripetal acceleration, V = velocity of the particle, r = radius of the circle.

Given:

Manjeet singh sold an article for ₹9000

gaining 1/5 of its C.P.

Formula used:

Profit percentage = (profit/ C.P) × 100

Calculation: 

Let cost price be x

⇒ Profit = (1/5) × x 

⇒ Selling price = Cost price + profit 

⇒ 9000 = x + 1/5 x

⇒ 6/5 x = 9000

⇒ Cost price = Rs. 7500

Profit = 1/5 × 7500 ⇒ Rs.1500 

Profit percentage = (profit/ C.P)× 100

⇒ (1500/7500)× 100

⇒ 20%

∴ The gain % is 20%.

Alternate Method

Let CP be Rs.1

Profit = 1/5 of CP = Rs.1/5  

Profit % = (profit/ C.P) × 100

Profit % = (1/5)/1 × 100 ⇒ 20%

∴ The gain % is 20%.

Given:

⇒ The Average of these numbers = Sum/5 = 5A/5 = A      ____( 2 )

⇒ As given The sum = 40 + A

⇒ 5A = 40 + A

⇒ 4A = 40

∴ A = 10 ( A is the middle term of the series )

Shortcut Trick

Apply the Successive Percentage Change formula: Net % Change = x + y + (xy/100).

Here, length decreases by 25% (x = −25) and breadth decreases by 14% (y = −14).

⇒ Net Change = −25 − 14 + [(−25 × −14) ÷ 100]

⇒ Net Change = −39 + (350 ÷ 100) = −39 + 3.5 = −35.5%.

The negative sign indicates a percentage decrease in the area.

∴ The correct answer is 35.5%.

Alternate Method

Given: Original Length = 8 cm, Original Breadth = 50 cm.

Formula Used: Area of Rectangle = Length × Breadth; Percentage Decrease = (Decrease ÷ Original Value) × 100.

⇒ Original Area = 8 × 50 = 400 cm²

⇒ New Length after 25% loss = 8 − (25% of 8) = 8 − 2 = 6 cm

⇒ New Breadth after 14% loss = 50 − (14% of 50) = 50 − 7 = 43 cm

⇒ New Area = 6 × 43 = 258 cm²

⇒ Decrease in Area = 400 − 258 = 142 cm²

⇒ Percentage Decrease = (142 ÷ 400) × 100

⇒ Percentage Decrease = 142 ÷ 4 = 35.5%

∴ The correct answer is 35.5%.

Additional Information

Shortcut Trick

When the side of a square increases by x%, the area increases by 2x + (x²/100)%.

Here, x = 20%.

Net percentage increase = 2(20) + (20 × 20 / 100)

Net change = 40 + 4 = 44%.

∴ The correct answer is 44%.

Alternate Method

Given: Increase in each side of the square = 20%.

Formula Used: Area of square = side × side

⇒ Let the initial side of the square be 10 units.

⇒ Initial Area = 10 × 10 = 100 sq units.

⇒ New side = 10 + (20% of 10) = 10 + 2 = 12 units.

⇒ New Area = 12 × 12 = 144 sq units.

⇒ Increase in Area = 144 − 100 = 44 sq units.

⇒ Percentage Increase = (Increase / Original Area) × 100

⇒ Percentage Increase = (44 / 100) × 100 = 44%.

∴ The correct answer is 44%.

Additional Information

⇒ 11.11%

∴ The gain% is 11.11%.

Given:

Vishal covers a distance of 20 km in 30 min

he covers half of the distance in 18 min.

Formula used:

Speed = Distance/Time.

Calculation:

According to the question,

Vishal covers a distance of 20 km in 30 min, he covers half of the distance in 18 min.

Remaining distance left to the covered = 20 – 10 ⇒ 10 km

Remaining time = 30 – 18 ⇒ 12 min

Convert minutes into hours = 12 × 1/60 hours ⇒ 12/60 hours

Speed = Distance/Time

Speed = 10/(12/60) ⇒ 50 km/hr

∴ His speed to cover the remaining distance is 50 km/hr.

Given:

A shopkeeper gives two successive discounts of 20% and 15% on a book whose marked price is Rs. 850.

Formula used:

Successive discount = a + b – ab/100.

Selling price = Marked price – Discount.

Calculation:

Successive discount of a and b, a= 20% and b = 15%

According to the successive discount formula,

Total discount of a% and b% = 20 + 15 – (20 × 15)/100

⇒ 35 – 3

⇒ 32%

Discount = 32% of the marked price

⇒ Discount = (32/100) × 850

⇒ Discount = 272

Selling price = Marked price – Discount

⇒ Selling price = 850 – 272

⇒ 578

∴ The selling price of the book is Rs. 578.

Shortcut Trick

Total discount of a% and b% = 20 + 15 – (20 × 15)/100

⇒ 35 – 3

⇒ 32%

Selling Price = Marked price × (100 - Discount%/100

⇒ 850 × (68/100)

⇒ 578

∴ The selling price of the book is Rs. 578.

Given:

A wins by the margin of 480 votes

A gets 70% of the total votes

Calculation:

Let the total number of votes polled be x.

According to the question

Then, 70% of x = 30% of x + 480

⇒ 70x/100 = 30x/100 + 480

⇒ (70 – 30)x/100 = 480

⇒ x = (480 × 100)/40

⇒ x = 1200

∴ Total number of votes polled is 1200. 

 

Shortcut Trick

A gets 70% vote, then B gets 30% vote

according to question,

⇒ 70% – 30% = 480

⇒ 40% = 480

⇒ 1% = 12

⇒ 100% = 1200

∴ Total number of votes polled is 1200.

Calculation:

According to the bar graph,

Average production (in 10000 tonnes) of 1999 and 2000 = (65 + 50)/2

1998 and 2000 = (45 + 50)/2

⇒ 47.5

1996 and 1997 = (40 + 60)/2

⇒ 50

2000 and 2001 = (50 + 75)/2

⇒ 62.5

1995 and 2001 = (25 + 75)/2

⇒ 50

∴ The average production of 1999 and 2000 is less than the average production of 2000 and 2001.

Initial ratio of Milk : Water is 2 : 1. To make milk units consistent with the new ratio 4 : 3, multiply the initial ratio by 2.

New representation of initial ratio = 4 : 2 (Total 6 units).

Given, 6 units = 60 liters ⇒ 1 unit = 10 liters.

Difference in water units = 3 − 2 = 1 unit.

Added water = 1 unit × 10 = 10 liters.

∴ The correct answer is 10 liters.

Alternate Method

Given: Total mixture = 60 liters, Initial ratio (M:W) = 2 : 1, Final ratio (M:W) = 4 : 3.

⇒ Quantity of Milk = (2/3) × 60 = 40 liters.

⇒ Quantity of Water = (1/3) × 60 = 20 liters.

⇒ Let the quantity of water added be x liters.

⇒ New ratio: 40 / (20 + x) = 4 / 3.

⇒ 40 × 3 = 4 × (20 + x).

⇒ 120 = 80 + 4x.

⇒ 4x = 120 − 80 = 40.

⇒ x = 40 / 4 = 10.

∴ The correct answer is 10 liters.

Additional Information

Ratio Balancing Method

Ratio of efficiency of A : B = 2 : 1.

Total efficiency of (A + B) = 2 + 1 = 3 units/day.

Total work = Total efficiency × Total days = 3 × 20 = 60 units.

Time taken by A alone = Total work ÷ Efficiency of A = 60 ÷ 2 = 30 days.

∴ The correct answer is 30 days.

Alternate Method

Given:

Efficiency of A is twice that of B.

Time taken by (A + B) together = 20 days.

Formula Used:

Total Work = Efficiency × Time

Calculations:

⇒ Let the efficiency of B be 1 unit/day.

⇒ Then, efficiency of A = 2 × 1 = 2 units/day.

⇒ Combined efficiency of (A + B) = 2 + 1 = 3 units/day.

⇒ Total work = Combined efficiency × Number of days together

⇒ Total work = 3 × 20 = 60 units.

⇒ Days taken by A alone = Total Work ÷ Efficiency of A

⇒ Days taken by A = 60 ÷ 2 = 30 days.

∴ The correct answer is 30 days.

Additional Information

Efficiency and Time Relationship

The time taken to complete a work is inversely proportional to the efficiency of the worker (Time ∝ 1/Efficiency).

Combined Work Formula

If A completes a work in x days and B in y days, they together complete it in (x × y) ÷ (x + y) days.

Work and Wages

Wages are distributed in the direct ratio of efficiency of the workers if they work for the same duration.

Shortcut Trick

Combine ratios A : B and B : C by making the common term B equal.

A : B = 1 : 2 (multiply by 3) → 3 : 6

B : C = 3 : 5 (multiply by 2) → 6 : 10

Combined ratio A : B : C = 3 : 6 : 10. Total parts = 3 + 6 + 10 = 19 units.

19 units → ₹3800 | 1 unit → ₹200 | B's share (6 units) → 6 × 200 = ₹1200.

∴ The correct answer is ₹1200.

Alternate Method

Given:

Total amount = ₹3800

Ratio A : B = 1 : 2

Ratio B : C = 3 : 5

Formula Used:

Share of an individual = (Individual Ratio ÷ Sum of Ratios) × Total Amount

Calculations:

⇒ To find the combined ratio A : B : C, we equate B.

⇒ A : B = 1 : 2 = (1 × 3) : (2 × 3) = 3 : 6

⇒ B : C = 3 : 5 = (3 × 2) : (5 × 2) = 6 : 10

⇒ Combined Ratio A : B : C = 3 : 6 : 10

⇒ Sum of ratio parts = 3 + 6 + 10 = 19

⇒ B's share = (6 ÷ 19) × 3800

⇒ B's share = 6 × 200

⇒ B's share = 1200

∴ The correct answer is ₹1200.

⇒ 412

∴ The smallest number which when increased by 8 is exactly divisible by 4, 5, 6 and 7 = 412.

Given:

Gold is 12 times as heavy as aluminum and copper  is 5 times as heavy as aluminum.

Calculation:

Let the ratio of gold and copper that taken be x : y

According to the question,

⇒ $\frac{{12x + 5y}}{{x + y}} = \frac{8}{1}$

⇒ 12x + 5y = 8x + 8y

⇒ 4x = 3y

⇒ x/y = 3/4

∴ Gold and copper are taken in the ratio 3 : 4.  

Alternate Method

Allegation method use in this question,

∴ Gold and copper are taken in the ratio 3 : 4.

Shortcut Trick

To double an amount at simple interest, the Interest earned must be equal to 100% of the Principal.

Shortcut formula: Time (T) = 100 ÷ Rate (R)

⇒ Time = 100 ÷ 8

⇒ Time = 12.5 years.

∴ The correct answer is 12.5 years.

Alternate Method

Given:

Rate (R) = 8% p.a.

Let Principal (P) = P

Amount (A) = 2 × P = 2P

Formula Used:

Simple Interest (SI) = (P × R × T) ÷ 100

Amount (A) = P + SI

Calculations:

⇒ SI = A − P

⇒ SI = 2P − P = P

⇒ P = (P × 8 × T) ÷ 100

⇒ 1 = (8 × T) ÷ 100

⇒ 8 × T = 100

⇒ T = 100 ÷ 8

⇒ T = 12.5 years.

∴ The correct answer is 12.5 years.

Additional Information

Simple Interest Formula

Simple interest is calculated on the original principal for every period: SI = (P × R × T) ÷ 100.

Doubling of Sum (SI)

A sum of money doubles itself at Simple Interest when the time period T = 100 ÷ R years.

Tripling of Sum (SI)

A sum of money triples itself (Amount = 3P) when the total interest equals twice the principal. Time required T = 200 ÷ R years.

Rule of 72 (Compound Interest)

In Compound Interest, the approximate time to double an investment is T ≈ 72 ÷ R.

Given:

The Mean of a, b, c, d, and e = 36. And the Mean  of b, d, and e = 32

Formula Used:

Mean of a given series = Sum of the given series/Number of numbers in the series

Calculation:

⇒ The Sum of the a, b, c, d, e = 36 × 5 = 180      ____( 1 )

⇒ The Sum of the b, d, e = 32×3 = 96      ____( 2 )

⇒ from ( 1 ) & ( 2 ) we get

⇒ The Sum of the a and c = ( 1 ) – ( 2 ) = 180 – 96 = 84

∴ The Mean of a, c = 84/2 = 42

Given:

The average of first 6 terms is 36 and last 6 terms is 42,

The average of first 11 terms is 38.

Calculation:

The average of first 11 terms = 38.

The sum of first 11 terms = 38 × 11

⇒ 418

The average of first 6 terms = 36

The sum of first 6 terms = 36 × 6

⇒ 216

The average of last 6 terms = 42

The sum of last 6 terms = 42 × 6

⇒ 252

The sum of 12 terms = 216 + 252

⇒ 468

The 12th term = sum of 12 terms – sum of 11 terms 

⇒ 468 – 418

⇒ 50

∴ The 12th term is 50.

 

Shortcut Trick

The 12th term = (the sum of first 6 terms + the sum of last 6 terms) – the sum of first 11 terms

⇒ (216 + 252) – 418

⇒ 50

∴ The 12th term is 50.
