= 8 + 11 + 9 + 18 + 13 + 20

= 79

MAGIC = M (14) + A (26) + G (20) + I (18) + C (24)

= 14 + 26 + 20 + 18 + 24

= 102

Similarly,

LEAST = L (15) + E (22) + A (26) + S (8) + T (7)

= 15 + 22 + 26 + 8 + 7

Given, 

Cost price of 15  chains = Rs.7,520

Selling price of 15 chains = Rs.9,450

Therefore, Profit = Selling price - Cost price

= 9,450 - 7,520

= 1930

We know, Profit % = (profit/cost price) ×100

Profit % = (1930/7520) × 100 = 25.664 ≈ 26 %

Hence, option 1 is the correct answer.

Hence, option 2 is the correct answer.

The logic is as

(3 × 22) + (3 × 1) = 66 + 3 = 69

(7 × 17) + (4 × 2) = 119 + 8 = 127

(13 × 20) + (5 × 3) = 260 + 15 = 275

(26 × 15) + (6 × 4) = 390 + 24 = 414

Hence, the correct answer is 414.

Given:

Attendance required = 221 days

Calculation:

Number of days attended by student = 208

Let total attendance be n,

∴ ⇒ 208 + 5/100 × n = 221

⇒ n = 260

Total attendance days = 260

Attendance Required = 221/260 × 100 = 85

∴ Attendance required to appear in examination is 85%

Given:

Average score of section A = 92

New average of section A = 90

Formula:

Average = Sum of observations/number of observations

Calculation:

Total score of section A = 92 × 40 = 3680

Total score of moved students = 95 × 2 = 190

Total score after two students left = 3680 - 190 = 3490

Total new score after two students joined = 90 × 40 = 3600

Total score of new 2 students = 3600 - 3490 = 110

∴ Average of two new students = 110/2 = 55

Hence, Average score of new student is 55.

Given:

Amount = 729/625 × Sum

Formula used:

CI = P(1 + R/100)ⁿ - P

For Amount(A) Compounded half-yearly

A  = P(1 + (R/2)/100)²ⁿ

CI = P(1 + R/100)^a{1 + (1/b × R/100)} - P

Where, P = Principal, R = R%,

n = \(a\dfrac{1}{b}\) years , CI = Compound interest

Calculation:

Time = 1 year

⇒ Amount = P(1 + R/200)²

⇒ 729P/625 = P(1 + R/200)²

⇒ (27/25)² = (1 + R/200)²

⇒ 27/25 = 1 + R/200

⇒ R/200 = 2/25

⇒ R = 16%

CI = [10000(1 + 16/100)²{1 + (16/2)/100}] - 10000

CI = (13456 × 1.08) - 10000 = 4532.48

Hence, The Compound interest is Rs. 4532.

Given:

Radius of small balls = 7cm

Radius of cylindrical jar = 14cm

Formula:

Volume of cylinder = πr²h

Volume of sphere = 4/3 × πr³

Calculation:

Volume of six spherical balls = Volume of cylindrical jar

Volume of six spherical balls = 6 × 4/3 × 22/7 × 7³

Volume of cylindrical jar = 22/7 × 14² × h

Then,

⇒ 6 × 4/3 × 22/7 × 7³ = 22/7 × 14² × h

⇒ h = 14 cm

∴ Height of cylindrical jar is 14cm.

Given:

Dimensions of metallic slab = 35 × 11 × 20

Radius of wire = 0.7mm

Formula:

Volume of cuboid = l × b × h

Volume of cylinder = πr²h

Calculation:

Volume of metallic slab = 35 × 11 × 20 = 7700 cm³

Volume of cylindrical wire = 7700 cm3

Radius of wire = 0.7mm = 0.07cm

Volume of cylindrical wire = π × 0.07² × h

⇒ 7700 = 22/7 × 0.07 × 0.07 × h

⇒ h = 500000 cm

⇒ h = 5000 m

∴ Length of wire is 5000 m.

Given:

Sum = Rs.18600, Rate of interest = 5% and 8%

Time = 4 years, Simple interest = Rs.4800

Formula used:

SI = (P × R × T)/100

Where, P = Principal, R = rate of interest, T = time

Calculation:

Let amount invested at rate of interest 5% be Rs.a and 8% be Rs.(18600 - a)

⇒ 4800 = a × 5 × 4/100 + (18600 - a) × 8 × 4/100

⇒ 4800 = 20a/100 + 595200/100 - 32a/100

⇒ 12a/100 = 1152

⇒ a = 9600

Sum borrowed at 5% = Rs.9600

Sum borrowed at 8% = 18600 - 9600 = Rs.9000

Difference = 9600 - 9000 = 600

Hence, The difference in the money is Rs. 600

Shortcut Trick

Let MP = 100, Then SP = 100 - 10 = 90

⇒ CP × 135/100 = SP

⇒ CP = 90 × 100/135 = 66.67

If Discount = 20% i.e. 20% of 100 = 20

Then SP = 100 - 20 = 80

Profit = 80 - 66.67 = 13.33

Profit % = (13.33/66.67) × 100 = 20%

Alternate Method

Given:

Profit % = 35% and Discount % = 10%

Formula:

Profit = SP - CP 

Where SP = selling price, CP = Cost price

Profit % = (SP - CP)/CP × 100

Calculation:

Let the cost price of an article be Rs.100

⇒ 35 = (SP - 100)/100 × 100

Selling price = Rs.135, then

⇒ 135 = marked price × (100 - 10)/100

⇒ Marked price = Rs.150

SP for 20% discount = 150 × (100 - 20)/100 = Rs.120

Profit% for 20% discount = (120 - 100)/100 × 100 = 20%

Hence, the profit percentage for 20% discount is 20.

Given:

6 men can complete work in = 48 days

1 man = 2 women

Formula used:

M₁ × D₁ = M₂ × D₂

Where, M = number of men and D = days

Calculation:

Efficiency of women (W) = M/2

⇒ 6 × 48 = (4 + (8/2)) × D

⇒ D = (6 × 48)/8 = 36

Hence, The work will be completed in 36 days.

Shortcut Trick

Let The CP = x, Then 90% of x = 6750

⇒ x = 6750 × (100/90) = 7500

SP for 10% profit = 110% of CP

⇒ SP = (110/100) × 7500 = 8250.

Alternate Method

Given:

Loss = 10%

Selling price = Rs.6750

Formula:

Loss = CP - SP

Loss % = (CP - SP)/CP × 100

Profit % = (SP - CP)/CP × 100

Calculation:

⇒ 10 = (CP - 6750)/CP × 100

⇒ CP = 7500

Cost price of an article = Rs.7500. Then,

⇒ 10 = (SP - 7500)/7500 × 100

⇒ SP = 8250

∴ Selling price would be Rs.8250 when profit % is 10%.

Given:

LCM = 72

HCF = 3

Sum of numbers = 33

Formula:

LCM × HCF = product of numbers

Calculation:

Product of numbers = 72 × 3 = 216

Let two numbers be a and b.

⇒ ab = 216

⇒ a = 216/b

⇒ a + b = 33

⇒ 216/b + b = 33

⇒ b² - 33b + 216 = 0

Solving,

⇒ b² - 24b - 9b + 216 = 0

⇒ b(b - 24) - 9(b - 24) = 0

⇒ b = 24 or b = 9

⇒ a = 9 or a = 24

∴ Required difference = 24 - 9 = 15

Alternate Method

LCM = 72 and HCF = 3

Let, the numbers are 3a and 3b where a > b and a, b are prime to each other

Then, LCM of 3a and 3b = 3ab

3ab = 72 

⇒ ab = 24      ----(1)

Again, 3a + 3b = 33

⇒ a + b = 11      ----(2)

Squaring both sides of (2) and using (1) get,

(a + b)² = 11²

⇒ (a - b)² + 4ab = 121

⇒ (a - b)² = 121 - 4 × 24

⇒ (a - b) = 5      ----(3)            [∵ a > b, (a - b) > 0]

From (2) and (3) get,

a = 8 and b = 3

Difference in the number = 3a - 3b = 3 × (8 - 3) = 15

∴ The required difference in the number is 15.

Given:

Distance between two stations is 110km.

Length and Speed of first train is 1.8km and 90km/hr respectively.

Length and Speed of another train is 1.2km and 100km/hr respectively. 

Formula Used:

Speed = Distance/Time,

Relative speed when running opposite = Distance/Sum of the speed of both the trains

Calculation:

First train ran for 10 minutes, i.e. train will cover

⇒ 90 × 10/60 = 15 km

Actual distance to cover now = 110 – 15 = 95 km

Now both trains are running in opposite directions,

⇒ Relative speed = 100 + 90= 190 km/hr

Time required to cross = Distance to cover/Relative speed

⇒ Time taken = 95/190 = 1/2 hr

Distance covered by first train in 0.48 hour = 1/2 × 90 = 45 km

Total distance covered by first train = 15 + 45 = 60 km.

Actual distance covered till endpoint

⇒  Distance covered – length of a first train

⇒ 60 – 1.8 = 58.2 km

∴ Total distance covered from point A is 58.2 km.

Given:

Number is divided by 119 then leaves reminder 19.

Concept Used:

Dividend = Divisor × Quotient + Remainder

Calculation:

Let the quotient be 1,

⇒ Dividend = 119 × 1 + 19

⇒ Dividend = 119 + 19

⇒ Dividend = 138

Now when 138 is divided by 17,

⇒ 138/17

⇒ \(8\frac{2}{{17}}\)

∴ The remainder is 2
