Shortcut Trick

Use the weighted average deviation method from the target 30%.

Concentration A (15%) is −15% from 30%. Concentration B (30%) is 0% from 30%. Concentration C (45%) is +15% from 30%.

Net deviation = p × (−15) + 5 × (0) + 3 × (+15) = 0

⇒ −15p + 45 = 0 ⇒ 15p = 45 ⇒ p = 3

∴ The correct answer is 3.

Alternate Method

Given: Concentrations of Wine A = 15%, Wine B = 30%, Wine C = 45%. Mixing ratio = p : 5 : 3. Final concentration = 30%.

Calculations:

⇒ 30 = (15 × p + 30 × 5 + 45 × 3) ÷ (p + 5 + 3)

⇒ 30 × (p + 8) = 15p + 150 + 135

⇒ 30p + 240 = 15p + 285

⇒ 30p − 15p = 285 − 240

⇒ 15p = 45

⇒ p = 3

∴ The correct answer is 3.

Given:

Side of the square field = 63 m

Each horse is roped such that it can touch the middle of each side, hence the rope length = 63/2 = 31.5 m

π = 22/7

Formula Used:

Area of square = side²

Area grazed by one horse (quarter circle) = (1/4) × π × radius²

Remaining area = Area of square - 4 × Area grazed by one horse

Calculation:

Area of the square field = 63²

Area of the square field = 3969 m²

Radius of the quarter circle = 31.5 m

Area grazed by one horse = (1/4) × (22/7) × 31.5²

⇒ Area grazed by one horse = (1/4) × (22/7) × 992.25

⇒ Area grazed by one horse = (22 × 992.25) / 28

⇒ Area grazed by one horse = 21829.5 / 28

⇒ Area grazed by one horse ≈ 779.625 m²

Total area grazed by 4 horses = 4 × 779.625

Total area grazed by 4 horses ≈ 3118.5 m²

Remaining area = Area of square field - Total area grazed by 4 horses

⇒ Remaining area = 3969 - 3118.5

⇒ Remaining area ≈ 850.5 m²

The remaining area of the ground where the horses do not graze is 850.5 m².

Shortcut Trick

Convert the numbers into like decimals: 3.60, 0.54, 1.08.

Treat them as integers by removing the decimal: 360, 54, 108.

Find the HCF of 360, 54, and 108:

Factors of 54: 18 × 3 | 108: 18 × 6 | 360: 18 × 20. Thus, HCF = 18.

Apply the 2 decimal places back to the result: 0.18.

∴ The correct answer is 0.18.

Alternate Method

Given: Numbers are 3.6, 0.54, and 1.08.

Formula Used: HCF of Decimals = (HCF of numbers treated as integers) ÷ 10ⁿ (where n is the maximum decimal places).

Step-by-step calculation:

⇒ Convert numbers to fractions with same denominator: 360/100, 54/100, 108/100.

⇒ HCF of fractions = (HCF of Numerators) ÷ (LCM of Denominators).

⇒ Numerators are 360, 54, 108.

⇒ 54 = 2 × 3³

⇒ 108 = 2² × 3³

⇒ 360 = 2³ × 3² × 5

⇒ HCF (360, 54, 108) = 2¹ × 3² = 2 × 9 = 18.

⇒ Denominator LCM(100, 100, 100) = 100.

⇒ Final HCF = 18 ÷ 100 = 0.18.

∴ The correct answer is 0.18.

Given:

Principal (P) = ₹2,196

Rate (R) = 25%

Time (T) = 3 years

Formula Used: Compound Interest Formula: $A = P \left(1 + \frac{R}{100}\right)^T$

Instalment Formula: $A = \frac{P \times \left(1 + \frac{R}{100}\right)^T \times \frac{R}{100}}{ \left(1 + \frac{R}{100}\right)^T - 1}$

Calculation:

First, calculate the amount (A) to be paid after 3 years:

Rate (R) = 25% = 0.25

Time (T) = 3 years

Amount (A) after 3 years:

$A = 2196 \left(1 + 0.25\right)^3$

$A = 2196 \left(1.25\right)^3$

$A = 2196 \times 1.953125$

A = 4290

Now, calculate the annual instalment:

Instalment (I):

$I = \frac{2196 \times 1.953125 \times 0.25}{1.953125 - 1}$

$I = \frac{1072.5}{0.953125}$

I = 1125

The amount of instalment is ₹1125.

Given:

If A ∶ B ∶ C = 2 ∶ 3 ∶ 5

Formula Used:

To find the ratio (A)/(B):(B)/(C):(C)/(A)

Calculation:

Given A ∶ B ∶ C = 2 ∶ 3 ∶ 5

Let A = 2k, B = 3k, and C = 5k

Then, (A)/(B) = (2k)/(3k) = 2/3

(B)/(C) = (3k)/(5k) = 3/5

(C)/(A) = (5k)/(2k) = 5/2

The ratio (A)/(B) ∶ (B)/(C) ∶ (C)/(A) is (2/3) ∶ (3/5) ∶ (5/2)

To simplify, find a common denominator:

2/3 = 2 × 10 / 3 × 10 = 20 / 30

3/5 = 3 × 6 / 5 × 6 = 18 / 30

5/2 = 5 × 15 / 2 × 15 = 75 / 30

The ratio is 20 ∶ 18 ∶ 75

The correct answer is option 1.

Given:

Length of the train = 750 m

Length of the platform = 2 × 750 m = 1500 m

Speed of the train = 81 km/h

Formula Used:

Calculation:

Speed in m/s = 81 × (1000/3600)

Speed in m/s = 81 × (5/18)

Speed in m/s = 22.5 m/s

Total Distance = Length of the train + Length of the platform

Total Distance = 750 m + 1500 m

Total Distance = 2250 m

Time = Total Distance / Speed

⇒ Time = 2250 / 22.5

⇒ Time = 100 seconds

The time taken by the train to cross the platform is 100 seconds.

Given:

A number y, when reduced by 25%, becomes 120% of a second number z.

Calculation:

Let the original number y be y . When reduced by 25%, it becomes 0.75y .

Given that 0.75y = 1.2z

Solving for y in terms of z:

⇒ y = $\frac{1.2z}{0.75}$

⇒ y = $\frac{1.2}{0.75}z$

⇒ y = 1.6z

Therefore, y is 160% of z.

Hence, the correct answer is option 1.

Given:

A sum was invested at a certain rate of simple interest per annum for 2 years. Had it been invested at 3% per annum more rate than the existing rate, the simple interest accrued in the 2 years would have been ₹240 more.

Formula Used:

Simple Interest = (Principal × Rate × Time) / 100

Calculation:

Let the principal be ₹P and the original rate of interest be R%.

Simple interest at the original rate for 2 years = (P × R × 2) / 100

Simple interest at the increased rate (R+3)% for 2 years = (P × (R + 3) × 2) / 100

According to the question, the difference in interest is ₹240:

$\Rightarrow \frac{P \times (R + 3) \times 2}{100} - \frac{P \times R \times 2}{100} = 240$

$\Rightarrow \frac{P \times (2R + 6 - 2R)}{100} = 240$

$\Rightarrow \frac{2P \times 3}{100} = 240$

$\Rightarrow \frac{6P}{100} = 240$

$\Rightarrow 6P = 240 \times 100$

$\Rightarrow P = \frac{240 \times 100}{6}$

$\Rightarrow P = 4000$

The sum invested was ₹4,000.

Given:

Cost price of the bike for Deepak = ₹8,000

Profit made by Deepak = 40%

Loss incurred by Sharath = 30%

Formula Used:

Selling Price (SP) = Cost Price (CP) × (1 + Profit%)

Selling Price (SP) = Cost Price (CP) × (1 - Loss%)

Calculation:

Let's find the selling price of the bike when Deepak sold it to Sharath.

SP_Sharath = CP_Deepak × (1 + 40%)

SP_Sharath = 8000 × 1.40

SP_Sharath = ₹11,200

Now, let's find the cost price of the bike for Sivaji when Sharath sold it at a loss of 30%.

CP_Sivaji = SP_Sharath × (1 - 30%)

CP_Sivaji = 11,200 × 0.70

CP_Sivaji = ₹7,840

The cost price of the bike for Sivaji is ₹7,840.

Given:

Marked price (MP) of a book = ₹767

Discount = 20%

Profit = 30%

Formula Used:

Cost Price (CP) = SP / (1 + Profit%)

Calculation:

Discount = 20% of ₹767 = 0.20 × 767 = ₹153.40

SP = MP - Discount

SP = ₹767 - ₹153.40 = ₹613.60

Profit = 30%

CP = SP / (1 + Profit)

CP = ₹613.60 / 1.30

CP = ₹472

The cost price of the book is ₹472.

Given:

P's target marks = 360.

Total marks = 500.

P gets 5% less than the total marks, not the target marks.

We need to calculate how much P actually gets.

Solution:

Step 1: Calculate 5% of the total marks

5% of 500 = (5/100) × 500 = 25 marks.

Step 2: Subtract this from the target marks

P's actual marks = Target marks - 5% of total marks.

P's actual marks = 360 - 25 = 335 marks.

P gets 335 marks.

Given:

A and B together can complete a work in 15 days.

B and C together can complete a work in 12 days.

C and A together can complete a work in 10 days.

Formula Used:

1/A + 1/B + 1/C = 1/AB + 1/BC + 1/CA

Calculation:

Let the total work be W.

Work done by A and B in one day = W/15

Work done by B and C in one day = W/12

Work done by C and A in one day = W/10

Adding all three equations:

(W/15) + (W/12) + (W/10) = 2(1/A + 1/B + 1/C)

⇒ (4W + 5W + 6W) / 60 = 2(1/A + 1/B + 1/C)

⇒ 15W / 60 = 2(1/A + 1/B + 1/C)

⇒ 1/4 = 2(1/A + 1/B + 1/C)

⇒ 1/8 = 1/A + 1/B + 1/C

From the individual pairs:

1/A + 1/B = 1/15

1/B + 1/C = 1/12

1/C + 1/A = 1/10

Adding the three pairs:

2(1/A + 1/B + 1/C) = 1/15 + 1/12 + 1/10

⇒ 2(1/8) = 1/15 + 1/12 + 1/10

⇒ 1/4 = (4 + 5 + 6) / 60

⇒ 1/4 = 15/60

⇒ 1/4 = 1/4 (Verified)

Now, isolating 1/B:

1/B = (1/8) - (1/10)

⇒ 1/B = (5 - 4) / 40

⇒ 1/B = 1/40

Therefore, B alone can complete the work in 40 days.
