The logic followed here is:

Similarly,

Hence, 'CFS' is the correct answer.

1. 16 and 9

216 ÷ 16 × 9 + 24 - 27 = 126

⇒ 13.5 × 9 + 24 - 27 = 126

⇒ 121.5 + 24 - 27 = 126

⇒ 145.5 - 27 = 126

⇒ 118.5 ≠ 126

2. 27 and 9

216 ÷ 27 × 16 + 24 - 9 = 126

⇒ 8 × 16 + 24 - 9 = 126

⇒ 128 + 24 - 9 = 126

⇒ 152 - 9 = 126

⇒ 143 ≠ 126

3. 24 and 27

216 ÷ 9 × 16 + 27 - 24 = 126

⇒ 24 × 16 + 27 - 24 = 126

⇒ 384 + 27 - 24 = 126

⇒ 411 - 24 = 126

⇒ 387 ≠ 126

4. 9 and 24

216 ÷ 24 × 16 + 9 - 27 = 126

⇒ 9 × 16 + 9 - 27 = 126

⇒ 144 + 9 - 27 = 126

⇒ 153 - 27 = 126

⇒ 8 + 46.54 - 5 = 22

⇒ 54.54 - 5 = 22

⇒ 49.54 ≠ 22

2. - and +

8 - 32 ÷ 16 × 11 + 5 = 22

⇒ 8 + 2 × 11 - 5 = 22

⇒ 8 + 22 - 5 = 22

⇒ 30 - 5 = 22

⇒ 25 ≠ 22

3. ÷ and -

8 + 32 - 16 × 11 ÷ 5 = 22

Given data:

Initial distance = 225 m,

Speed of thief = 9 km/h,

Speed of policeman = 10 km/h,

Time = 4.2 min.

Concept used:

Relative Speed = Speed of policeman - Speed of thief.

The distance traveled = speed × time.

Solution:

Convert the speeds from km/h to m/min:

⇒ Speed of thief = 9000 m/60 min = 150 m/min,

⇒ Speed of policeman = 10000 m/60 min = 166.67 m/min

⇒ Relative speed = 166.67 m/min - 150 m/min = 16.67 m/min

⇒ Distance covered by policeman in 4.2 min = 16.67 m/min × 4.2 min = 70.01 m

⇒ Distance between them = Initial distance - Distance covered = 225 m - 70.01 m = 154.99 m ≈ 155 m.

∴ The distance between them is 155 m.

Given data:

Seat numbers in each class,

Occupancy percentage in each class,

Price per seat in each class.

Concept used:

Total income = (No. of seats × Occupancy rate × Price per seat)

Solution:

⇒ First class income = 50 seats × 30/100 × 2000 Rs = 30,000 Rs

⇒ Second class income = 100 seats × 50/100 × 1000 Rs = 50,000 Rs

⇒ Third class income = 150 seats × 100/100 × 500 Rs = 75,000 Rs

⇒ Income ratio per category = 30,000 ∶ 50,000 ∶ 75,000 = 6 ∶ 10 ∶ 15

∴ The first option is correct.

Given data:

Marked price = Rs. 1200, Two discounts = 8% and 6%.

Concept used:

Net discount = a + b - (ab/100),

where a and b are two successive discounts.

Solution:

⇒ Net discount = 8 + 6 - (8×6)/100 = 13.52%

⇒ Selling price = Marked price - Discount

⇒ 1200 Rs - (13.52/100 × 1200 Rs) = 1037.6 Rs

⇒ The selling price of the chair is Rs. 1037.76

∴ The selling price of the chair is Rs. 1037.76

Given data:

Number of toys purchased = 9, Number of toys given free = 3.

Concept used:

Discount % = (free quantity / (purchased quantity + free quantity)) × 100.

Solution:

⇒ Discount % = (3 / (9 + 3)) × 100 = 25%

⇒ The discount percentage is 25%.

∴ The discount percentage is 25%.

Shortcut Trick

Change in quantity = Initial − Final = 20 − 5.5 = 14.5 liters.

Percent change = (Change ÷ Initial base) × 100

⇒ Percent change = (14.5 ÷ 20) × 100

⇒ Percent change = 14.5 × 5 = 72.5%

∴ The correct answer is 72.5%.

Alternate Method

Given:

Initial amount of petrol in the tank = 20 liters

Final amount of petrol in the tank = 5.5 liters

Formula Used:

Percentage Change = (Difference in value ÷ Initial value) × 100

Calculations:

⇒ Change in petrol = Initial amount − Final amount

⇒ Change = 20 − 5.5 = 14.5 liters

⇒ Percentage Change = (Change ÷ Initial amount) × 100

⇒ Percentage Change = (14.5 ÷ 20) × 100

⇒ Percentage Change = 14.5 × 5

⇒ Percentage Change = 72.5%

∴ The correct answer is 72.5%.

Additional Information

Percentage Change

Percentage change indicates the degree of change over time, relative to the initial value. Formula: % Change = (New Value − Old Value) ÷ Old Value × 100.

Base Value in Percentage

Always calculate the percentage increase or decrease on the initial (old) value unless specifically mentioned otherwise in the question.

Successive Percentage Change

When a value is changed successively by a% and b%, the net percentage change is given by: (a + b + ab ÷ 100)%.

Shortcut Trick

Let total distance = LCM of 4 hours and 3.5 hours = 28 units.

Speed of 1st train = 28 ÷ 4 = 7 units/hr | Speed of 2nd train = 28 ÷ 3.5 = 8 units/hr.

Distance covered by 1st train in 2 hrs (6:00 a.m. to 8:00 a.m.) = 7 × 2 = 14 units.

Remaining distance = 28 − 14 = 14 units.

Time to cross after 8:00 a.m. = Distance ÷ Relative speed = 14 ÷ (7 + 8) = 14/15 hours = 56 minutes.

∴ The correct answer is 8:56 a.m.

Alternate Method

Delhi Jainagar Train 1 (6 a.m.) Speed: D/4

Train 2 (8 a.m.) Speed: 2D/7

8 a.m. Position

Meet at 8:56 a.m.

D/2 covered (6-8 a.m.) D/2 Remaining

Given:

Train 1 leaves Delhi at 6:00 a.m. and reaches Jainagar at 10:00 a.m.

Train 2 leaves Jainagar at 8:00 a.m. and reaches Delhi at 11:30 a.m.

Formula Used:

Speed = Distance ÷ Time

Time to meet = Remaining Distance ÷ Relative Speed

Calculations:

Let the total distance between Delhi and Jainagar be D.

⇒ Time taken by Train 1 = 10:00 a.m. − 6:00 a.m. = 4 hours.

⇒ Time taken by Train 2 = 11:30 a.m. − 8:00 a.m. = 3.5 hours = 7/2 hours.

⇒ Speed of Train 1 = D/4

⇒ Speed of Train 2 = D ÷ (7/2) = 2D/7

⇒ By 8:00 a.m., Train 1 travels for 2 hours (6:00 a.m. to 8:00 a.m.).

⇒ Distance covered by Train 1 = 2 × (D/4) = D/2

⇒ Remaining distance at 8:00 a.m. = D − D/2 = D/2

Now, both trains are moving towards each other.

⇒ Relative speed = D/4 + 2D/7 = (7D + 8D) / 28 = 15D/28

⇒ Time taken to meet = (D/2) ÷ (15D/28)

⇒ Time taken = (D/2) × (28/15D) = 14/15 hours.

⇒ Convert 14/15 hours into minutes: 14/15 × 60 = 56 minutes.

⇒ The trains meet 56 minutes after 8:00 a.m., which is 8:56 a.m.

∴ The correct answer is 8:56 a.m.

Additional Information

Relative Speed Concept

When two bodies travel in opposite directions at speeds S₁ and S₂, their relative speed is S₁ + S₂. Time to meet = Distance between them ÷ Relative Speed.

Direct Formula for Meeting Time

If Train 1 takes time T₁, Train 2 takes time T₂, and Train 1 starts Δt hours early, the time to meet after Train 2 starts is: Time = (T₁ − Δt) × T₂ ÷ (T₁ + T₂).

LCM Method for Constant Distance

When only travel times are given for a fixed distance, assuming the total distance as the Least Common Multiple (LCM) of the given times entirely eliminates fractional calculations and speeds up the process.

Given data:

The car runs 450 km on 35 liters of petrol, We need to find how far it can go on 25 liters.

Concept used:

Use the ratio of distances and fuel to find out how far the car can go.

Solution:

⇒ Distance per litre = 450 km / 35 litres = 12.86 km/litre

⇒ Distance for 25 litres = 25 litres × 12.86 km/litre = 321.43 km

Therefore, the car can run approximately 321.43 km on 25 litres of petrol.

Given:

Anay does 5/11 of the work in 10 days

⇒ Anay completes the work in 22 days

Rohan does 5/6 of the work in 15 days

⇒ Rohan completes the work in 18 days

Rohan left 5 days before the completion

Formula Used:

Total Work = Efficiency × Time

Calculation:

Let the total work be 198 units (LCM of 18 and 22)

⇒ Efficiency of Anay = 198/22 = 9 units/day

⇒ Efficiency of Rohan = 198/18 = 11 units/day

Let the total time required be 'x' days

According to the question,

9x + 11(x - 5) = 198

⇒ 9x + 11x - 55 = 198

⇒ 20x = 253

⇒ x = 253/20

Rohan left 5 days before the completion

⇒ Rohan worked for (253/20 - 5) = (253 - 100)/20 = 153/20 days

∴ Rohan left work after 153/20 days.

Given data: 

A can do the work in 7 days,

B can do the work in 14 days.

Concept Used:

Total Work = LCM of total number of days

Efficiecny = Total Work/Total number day 

Solution:

The LCM of 7 and 14, is 14 = the total work.

⇒ Calculate A's work per day: 14/7 = 2 units/day.

⇒ Calculate B's work per day: 14/14 = 1 unit/day.

Work done by A and B in two days:

⇒ 2 units (by A on the first day) + 1 unit (by B on the second day) = 3 units.

Determine the amount of work done in 8 days,

⇒ 4 sets of 2-day intervals: 4 × 3 = 12 units.

On the 9th day,

⇒ A will work and complete the remaining 2 units of work.

Therefore, the work will be completed in 9 days when they both work on alternate days starting with A.

Shortcut Trick Net profit percentage can be calculated directly using the successive percentage formula: Overall Change % = x + y + (x × y) ÷ 100 Here, markup (x) = +12% and discount (y) = −6% ⇒ Net Profit % = 12 − 6 + [12 × (−6)] ÷ 100 ⇒ Net Profit % = 6 − 0.72 = 5.28% ∴ The correct answer is 5.28%.

Alternate Method Given: Markup Percentage = 12% Discount Percentage = 6% Formula Used: Marked Price (MP) = CP + (Markup % of CP) Selling Price (SP) = MP − (Discount % of MP) Profit % = [(SP − CP) ÷ CP] × 100

CP = 100

MP = 112

SP = 105.28

+12% Markup

−6% Discount

Profit = +5.28%

Calculations: Let the Cost Price (CP) be 100. ⇒ MP = 100 + (12% of 100) = 100 + 12 = 112 ⇒ Discount given = 6% of 112 = (6 × 112) ÷ 100 = 6.72 ⇒ Selling Price (SP) = 112 − 6.72 = 105.28 ⇒ Profit = SP − CP = 105.28 − 100 = 5.28 ⇒ Profit % = (Profit ÷ CP) × 100 = (5.28 ÷ 100) × 100 = 5.28% ∴ The correct answer is 5.28%.

Additional Information Successive Percentage Formula When a value is first changed by x% and then by y%, the net percentage change is given by x + y + (x × y) ÷ 100. Markup is treated as a positive value and discount as a negative value. Relation between CP, MP, and SP The Marked Price is always calculated by increasing the Cost Price by the given markup percentage. A discount is then applied exclusively on the Marked Price to deduce the Selling Price. Evaluating Profit or Loss Profit or loss is strictly evaluated on the base Cost Price. The formula is Profit % = [(SP − CP) ÷ CP] × 100. If SP > CP, the difference indicates a profit; otherwise, it is a loss.

Ratio of Toluene to Acetone = 4 : 1.

Difference between Mean Price and Acetone = 16 − 14 = 2.

In the Alligation cross, 4 units of Toluene correspond to a difference of 2.

Therefore, 1 unit corresponds to 2 ÷ 4 = 0.5.

Cost of Toluene = Mean Price + 0.5 = 16 + 0.5 = 16.5.

∴ The correct answer is ₹16.5.

Alternate Method

Given:

Cost of Acetone (Cheaper) = ₹14/litre

Cost of Mixture (Mean) = ₹16/litre

Ratio of Toluene to Acetone = 4 : 1

Formula Used:

(Quantity of Cheaper) ÷ (Quantity of Dearer) = (Price of Dearer − Mean Price) ÷ (Mean Price − Price of Cheaper)

Calculations:

⇒ Let the cost of Toluene be ₹x per litre.

⇒ According to the Alligation Rule:

⇒ (Quantity of Acetone) ÷ (Quantity of Toluene) = (x − 16) ÷ (16 − 14)

⇒ 1 ÷ 4 = (x − 16) ÷ 2

⇒ 2 ÷ 4 = x − 16

⇒ 0.5 = x − 16

⇒ x = 16 + 0.5

⇒ x = 16.5

∴ The correct answer is ₹16.5.

Additional Information

Shortcut Trick

Identify Pythagorean triplets for the diagonal value 10: 6, 8, 10.

Check if the sum of sides matches the semi-perimeter: 6 + 8 = 14 cm.

Since 2 × (6 + 8) = 28 cm (given perimeter), the dimensions are 6 cm and 8 cm.

Area of rectangle = 8 × 6 = 48 cm².

∴ The correct answer is 48 cm².

Alternate Method

Given: Diagonal (d) = 10 cm, Perimeter (P) = 28 cm.

Formula Used: Perimeter = 2(L + B); Diagonal² = L² + B²; Area = L × B.

⇒ 2(L + B) = 28

⇒ L + B = 14 cm

⇒ (L + B)² = L² + B² + 2LB

⇒ 14² = (Diagonal)² + 2 × Area

⇒ 196 = 10² + 2 × Area

⇒ 196 = 100 + 2 × Area

⇒ 2 × Area = 196 − 100 = 96

⇒ Area = 96 ÷ 2 = 48 cm²

∴ The correct answer is 48 cm².

Additional Information

Relationship between Perimeter, Diagonal and Area

For any rectangle, the relationship is given by: (Semi-Perimeter)² = Diagonal² + 2 × Area.

Given data:

Rashika received 54% votes,

Rashika won by 1280 votes.

Concept used:

Difference in percentage votes is equal to the winning margin.

Solution:

Assume the total number of votes is 'V'.

Rashika received 54% of 'V' votes, i.e., 0.54V

Nikita received the remaining votes, i.e., (1 - 0.54)V = 0.46V

The difference between Rashika's votes and Nikita's votes is 1280, which can be represented as:

⇒ 0.54V - 0.46V = 1280

Solve the above equation for 'V' to get the total number of votes.

Therefore, substituting the values from step 4 into the equation:

⇒ 0.08V = 1280

⇒ V = 1280 / 0.08 = 16,000

Hence, the total number of votes cast in the election was 16,000.

Given data:

Principal = Rs. 40,000, Rate = 8% per annum, Time = 1.5 years, Compounded half-yearly.

Concept used:

Compound Interest formula = P(1 + r/n)^(nt)

Solution:

Convert annual interest rate to a decimal and time period to half-years:

⇒ r = 8/100 = 0.08

⇒ t = 1.5 × 2 = 3 half-years

Substitute given values into the formula for compound interest:

⇒ A = P(1 + r/n)^(nt)

Therefore, substituting the values from step 1 into the equation:

⇒ A = 40000(1 + 0.08/2)^(2 × 1.5)

⇒ A = 40000(1 + 0.04)³

⇒ A = 40000 × 1.124864

⇒ A ≈ Rs. 44,995

Therefore, the approximate amount received at the end of one and half years is Rs. 44,995.

Shortcut Trick

Rate of interest for 6 months = 8/2 = 4%

In CI, we get interest on interest

Shortcut Trick

Rate 20% = 1/5 → Principal : Installment ratio for 1st year = 5 : 6

For 2nd year, square the ratios → Principal : Installment = 5² : 6² = 25 : 36

Equalize installments: Multiply 1st year ratio by 6 → (5 × 6) : (6 × 6) = 30 : 36

Total Principal units = 30 + 25 = 55 units

55 units = ₹9350 ⇒ 1 unit = ₹170

Value of each installment = 36 units = 36 × 170 = ₹6120

∴ The correct answer is ₹6120.

Alternate Method

Given:

Loan Amount (P) = ₹9350

Rate of Interest (R) = 20% per annum

Number of installments (n) = 2

Formula Used:

P = [x / (1 + R/100)¹] + [x / (1 + R/100)²] + ... where x is the equal installment.

Calculations:

⇒ 9350 = x / (1 + 20/100) + x / (1 + 20/100)²

⇒ 9350 = x / (1.2) + x / (1.44)

⇒ 9350 = x / (6/5) + x / (36/25)

⇒ 9350 = 5x/6 + 25x/36

⇒ 9350 = (30x + 25x) / 36

⇒ 9350 = 55x / 36

⇒ x = (9350 × 36) / 55

⇒ x = 170 × 36

⇒ x = ₹6120

∴ The correct answer is ₹6120.

Additional Information

CI Installment General Formula

For n equal installments, P = x[1/(1+r) + 1/(1+r)² + ... + 1/(1+r)ⁿ], where r is the rate per period in decimal.

SI vs CI Installments

In CI installments, interest is charged on the reducing balance (present value), whereas SI installments often involve interest on the total amount or specific due balances.

Effective Rate of Interest

If compounded half-yearly, the rate is halved (R/2) and the number of periods is doubled (2n) in the installment formula.

Shortcut Trick

A number is divisible by 44 if it is divisible by both 4 and 11.

For divisibility by 4: Last two digits K2 must be divisible by 4 → K can be 1, 3, 5, 7, 9.

For divisibility by 11: (4+9+1+2) − (2+7+K) = 14 − (9+K) = 5 − K must be 0 or a multiple of 11.

If 5 − K = 0 ⇒ K = 5 (Check: 52 is div by 4). If we check options, K = 5 is present.

Wait, checking K = 7 from options: (4+9+1+2) − (2+7+7) = 16 − 16 = 0. Also 72 is div by 4.

∴ The correct answer is 7.

Alternate Method

Given: Number = 42971K2, Divisor = 44.

Condition: Divisibility by 44 requires divisibility by 4 and 11.

⇒ Divisibility by 4: The last two digits K2 must be divisible by 4. Possible K = 1, 3, 5, 7, 9.

⇒ Divisibility by 11: Difference of sums of digits at odd and even places must be 0 or multiple of 11.

⇒ Sum (Odd) = 4 + 9 + 1 + 2 = 16

⇒ Sum (Even) = 2 + 7 + K = 9 + K

⇒ Difference = 16 − (9 + K) = 7 − K

⇒ For difference to be 0: 7 − K = 0 ⇒ K = 7.

⇒ Checking K = 7 in K2 → 72, which is divisible by 4 (18 × 4 = 72).

∴ The correct answer is 7.

Additional Information

Divisibility Rule of 4

A number is divisible by 4 if the last two digits of the number are divisible by 4 or are both zero.

Divisibility Rule of 11

Subtract the sum of digits in even positions from the sum of digits in odd positions. If the result is 0 or divisible by 11, the number is divisible by 11.

Composite Divisibility

To check divisibility by a composite number n, check divisibility by its co-prime factors (e.g., for 44, factors are 4 and 11).

Shortcut Trick

When the time period is equal, the profit share ratio directly equals the investment ratio.

Investment ratio (Ram : Robert : Rahim) = 50000 : 30000 : 40000 = 5 : 3 : 4.

We can skip calculating the actual profit shares and directly compare their ratio parts.

Ratio of Rahim's share to Robert's share = 4 : 3.

∴ The correct answer is 4 : 3.

Alternate Method

Given:

Ram's investment = Rs. 50,000

Robert's investment = Rs. 30,000

Rahim's investment = Rs. 40,000

Total profit = Rs. 18,000

Time period is constant for all.

Formula Used:

Profit Ratio = (Capital₁ × Time₁) : (Capital₂ × Time₂)

When time is constant, Profit Ratio = Ratio of Capitals

50,000 Ram (Part: 5)

30,000 Robert (Part: 3)

40,000 Rahim (Part: 4)

Rahim's Share : Robert's Share = 4 : 3

Calculations:

⇒ Profit ratio of Ram : Robert : Rahim = 50000 : 30000 : 40000

⇒ Profit ratio = 5 : 3 : 4

⇒ Total ratio parts = 5 + 3 + 4 = 12 parts

⇒ 12 parts = Rs. 18,000

⇒ 1 part = 18000 ÷ 12 = Rs. 1500

⇒ Robert's share = 3 parts × 1500 = Rs. 4500

⇒ Rahim's share = 4 parts × 1500 = Rs. 6000

⇒ Ratio of Rahim's share to Robert's share = 6000 : 4500

⇒ Ratio = 60 : 45 = 4 : 3

∴ The correct answer is 4 : 3.

Additional Information

Compound Partnership

When investments are made for different time durations, the profit ratio is calculated as the ratio of the products of capital and time (C₁ × T₁ : C₂ × T₂).

Working vs Sleeping Partners

A working partner actively manages the business and gets a fraction of the profit as a salary. The remaining profit is then distributed among all partners according to their investment ratio. A sleeping partner only provides the capital without actively managing.

Investment Ratio Shortcut

When finding the ratio between two specific partners out of a group, the total absolute profit value is not required. You can directly compare their proportional investment parts to save calculation time.
