• Thus, the non-Muslim cultivators were encouraged to adopt Islam, so that they could sustain their agricultural holdings.

Important Points

• There are different types of tax imposed during the Delhi sultanate:
• Kharaj was a land tax that was equal to one-tenth of the produce of the land.
• Zakat was a tax on property realized by the Muslims.
• Kham was one-fifth of the booty captured, a tax on mines, treasure troves, and a share on war booty.
• Jaziya: levied on the non-Muslim subjects, particularly the Hindus. Women and children were, however, exempted from the taxes.

Additional Information

• The time period of the Delhi Sultanate was from 1206-1526.
• The five dynasties ruled over the Delhi Sultanate sequentially they are as follows:
• The Mamluk Dynasty/ Slave Dynasty (1206-1290).
• The Khilji Dynasty (1290-1320).
• The Tughlaq Dynasty (1320-1414).
• The Sayyid Dynasty (1414-1451).
• The Lodhi Dynasty (1451-1526).
• Illtutmish was known as the real founder of the Delhi Sultanate.

Formula used:

Time at which bells would ring together = Time duration ÷ LCM

Calculation:

LCM of 12, 9, 8, 6, 3, and 10 minutes = 360 min or 6 hours

Times they would ring in 12 hours = 12 ÷ 6 = 2 times. 

∴ The bells would ring for 2 times together in the 12 hours.

Given:

height of cylinder = 20 cm

Volume of cylinder = 6930 cm2  

Formula:

V = π × r2 × h

Curved surface area = 2πrh

Where "r" is the radius, "V" is the volume of cylinder, and "h" is the Height of the right circular cylinder.

Calculation:

From volume of the cylinder formula-

⇒ r = $\sqrt {V \over πh}$

Substituting the values,

⇒ r = $\sqrt {6930 \over {22\over7}× 20}$ = 10.5 cm

Using the value of radius in the Curved surface area formula-

⇒ Curved surface area = 2 × $22\over7$ × 10.5 × 20 =  1,320 cm2

The curved surface area of the cylinder is 1320 cm2

Concept: 

Cutting rope for getting the pieces of equal length would mean finding HCF of the individual length of the rope pieces.

Calculation:

HCF of 21 m , and 42 m = 21 m

∴ The maximum possible length of each pieces is 21 m.

Calculation:

Let the number be "a"

According to the question-

⇒ $60\over100$ × a -  $30\over100$ × a = 15

⇒  $30\over100$ × a = 15

∴ a = 15 × $100\over30$ = 50

The number is 50.

⇒  $7-\frac{9}{7}$ of $\frac{7}{3} ÷ \frac{3}{7}$ of $\frac{7}{9}+3\left(2-\frac{2}{7} ÷ \frac{1}{7}\right)$ 

⇒  $7-\frac{9}{7}$ of $\frac{7}{3} ÷ \frac{3}{7}$ of $\frac{7}{9}+3\left(2-\frac{2}{7} × \frac{7}{1}\right)$ 

⇒  $7-\frac{9}{7}$ of $\frac{7}{3} ÷ \frac{3}{7}$ of $\frac{7}{9}+3 × 0$

⇒  $7-3$  ÷ $\frac{1}{3}$ \()+ 0

⇒ 7 - 9 

⇒ -2 

The answer is -2.

Calculation:

From the question, we have-

X : Y = 5 : 6

X : Z = 4 : 7

Multiplying X : Y by 4 and X : Z by 5, we have-

⇒ X : Y = 20 : 24

⇒ X : Z = 20 : 35

∴ X : Y : Z = 20 : 24 : 35

According to the question-

Difference between Y and Z = 35 - 24 = 11

⇒ $11\over 20+24+35$ × ₹9,480 = ₹1320

The difference is ₹1320.

Formula:

A = P × (1 + $R\over 100$)T

CI = A - P

where-

A = Amount

P = Principal

R = Rate

T = Time

CI = Compound Interest

Calculation:

According to the question-

⇒ A = ₹12,500 × (1 + $12\over 100$)$11\over4$

⇒ A = ₹12,500 × (1.12)^2.75

⇒ A = ₹12,500 × 1.3673 = ₹17,091

∴ CI = ₹17,091 - ₹12,500 = ₹4,591

The compound interest on the principal is ₹4,591.

Formula:

Effective discount rate = d1 + d2 - $d_1 × d_2 \over 100$

Where “d1” and “d2” are successive discount rates.

SP = MP - $D\over100$ × MP, where

MP = Marked price, SP = Selling Price

D = Effective discount rate

Calculated:

Effective discount = 20 + 15 - $20 × 15 \over 100$ = 32%

Substituting the values, in the SP formula, we get-

⇒ SP = 2,000 - $32\over100$ × 2,000 = 2000 - 640 = Rs 1,360

∴ The selling price of the article is Rs 1,360.

Calculation:

From the question, we have-

A : B = 3 : 5

B : C = 2 : 7

Multiplying A : B by 2 and B : C by 5, we have-

⇒ A : B = 6 : 10

⇒ B : C = 10 : 35

A : B : C = 6 : 10 : 35

Let the total amount be "a"

According to the question-

⇒ $6\over (6 +10+35)$ × a = 3600

⇒ $6\over 51$ × a = 3600

⇒  a = 3600 × $51\over6$ = Rs 30,600

∴ The amount is Rs 30,600.

Formula:

A = L × B, where

A = Area of rectangle

L = Length of the rectangle

B = Breadth of the rectangle

Calculation:

From the figure, 

Area of pool = 90 m × 30 m = 2700 m²

Let the width of the walkway be "a" m.

Length of walkway = 90 + a + a = (90 + 2a) m

Breadth of walkway = 30 + a + a = (30 + 2a) m

Area of complete figure = (90 + 2a) × (30 + 2a)

According to the figure -

Area of pool + Area of pathway = Area of complete figure

∴ (90 + 2a) × (30 + 2a) = 2700 + 2800

⇒ (90 + 2a) × (30 + 2a) = 5500

Solving we get-

⇒ 2700 + 180a + 60a + 4a² = 5500

⇒ 4a2 + 240a - 2800 = 0

⇒ a2 + 60a - 700 = 0

⇒ a2 + 70a - 10a - 700 = 0

⇒ a (a + 7) -10(a - 7) = 0

⇒ (a - 10)(a + 7) = 0

∴ a = 10 m since length/breadth cannot be negative.

Hence, the width of the walkway is 10 m.

Shortcut Trick The equation (90 + 2a) × (30 + 2a) = 5500 can be solve by factorising 5500 in form equal to (90 + 2a) × (30 + 2a).

⇒ 5500 can be written as 110 × 50

Further 110 can be written as (90 + 2 × 10)

Similarly, 50 can be written as (30 + 2 × 10)

⇒ (90 + 2a) × (30 + 2a) = (90 + 2 × 10) × (30 + 2 × 10)

This implies that a = 10 m.

Formula:

Efficiency = Total work ÷ Time taken to complete the work individually.

Calculation:

Time in which A can complete the work individually = $12\over {3\over5}$ = 12 × $5\over3$ = 20 days

Time in which B can complete the work individually =  $8\over {2\over3}$ = 8 × $3\over2$ = 12

LCM of 20 and 12 = 60

Let the total work be 60 units

Efficiency of A = 60 ÷ 20 = 3 units

Efficiency of B = 60 ÷ 12 = 5 units

Combined efficiency of A and B = 3 + 5 = 8 units/day

Total time taken to complete the work = 60 ÷ 8 = $7 {1\over 2}$ days

The work would be completed in $7 {1\over 2}$ days.

Formula:

SI = (P x R x T) / 100

Effective rate for T years = R × T

Where- 

P = Principal amount

R = Rate

T = Time

SI = Simple Interest

Calculation :

Let the principal be 100.

Effective rate for 1^st 3 years = 8 × 3 = 24%

Effective rate for next 4 years = 10 × 4 = 40%

Effective rate for next 5 years = 12 × 5 = 60%

Total effective rate of interest = 60% + 40% + 24% = 124%

⇒ SI = (100 x 124% x 1) / 100 = 124

∴ Principal when SI is Rs 13,795 = 13,795 × $100\over124$ = Rs 11,125

∴ The amount invested is Rs 11,125.

Formula:

Total profit made by the man = $4\over100$ × ₹ 2,400 = ₹ 96

Selling price = ₹ 2,400 + ₹ 96 = ₹ 2,496

Let the cost price of table be Rs "a".

⇒ Cost price of chair = ₹ 2,400 - a

According to the question-

⇒ $112\over100$ × a + $90\over100$ × (₹2400 - a) = ₹2,496

⇒ 112a + ₹216,000 - 90a = ₹249,600

⇒ 22a = ₹33,600

⇒ a = ₹1,527

∴ The cost price of the table is ₹1,527.

Calculation:

Difference of error = ${9\over 2}$ - ${2\over 9}$ = ${81-4\over 18}$ = ${77\over 18}$

Difference % = ${77\over 18}\over {9\over2}$ × 100 = ${77\over 18}$ × ${2\over 9}$ × 100 = 95%

∴ The approximate error percentage in the calculation is 95%.

Concept: 

B = Bar/Bracket, O = Off, D = Division, M = Multiplication

A = Addition, S = Subtraction

Calculation:

6 ÷ [4 × 3 {5 × 4 ÷ (5 of 4 + 4 ÷ 2 × 4)}]

⇒ 6 ÷ [4 × 3 {5 × 4 ÷ (20 + 4 ÷ 2 × 4)}]

⇒ 6 ÷ [4 × 3 {5 × 4 ÷ (20 + 2 × 4)}]

⇒ 6 ÷ [4 × 3 {5 × 4 ÷ (20 + 8)}]

⇒ 6 ÷ [4 × 3 {5 × 4 ÷ 28}]

⇒ 6 ÷ [4 × 3 {5 × $1\over7$}]

⇒ 6 ÷ [4 × 3 {$5\over7$}]

⇒ 6 ÷ [4 × $15\over7$]

⇒ 6 ÷ $60\over7$

⇒ ${7\over 10}$

∴ The value of the expression is ${7\over 10}$.

Concept:

Δ ABC is a right-angled triangle.

According to the Pythagorean theorem-

⇒ h² = l² + b², where

h = Hypotenuse, l = Perpendicular, b = Base

Calculation:

Applying pythagoras, theorem in Δ BCD, we get-

⇒ 15² + 15² = BC²

BC² = 450 or BC = 15√2

From the figure, we know that BC = Diagonal of the square ABCD

Hence, BC : BD = 15√2 : 15 or 2 : 1

∴ The ratio is √2 : 1.

Formula:

Average weight = Total weight of all persons ÷ Total persons in the group

Calculation:

Total males in the group = $5\over 9$ × 45 = 25

Total females in the group = $4\over 9$ × 45 = 20

Total weight of all the males = 79.4 kg × 25 = 1,985 kg

Total weight of all the females = 64.5 kg × 20 = 1,290 kg

Total weight of all the persons = 1,985 + 1,290 = 3,275 kg

Average weight = 3,275 ÷ 45 = 72.8 kg (corrected to one decimal place)

∴ The average weight of all individuals in the group is 72.8 kg.

Formula:

Efficiency = Total time taken to complete the task ÷ Time taken to complete the task individually. 

Calculation:

Let Efficiency of sonu, manu, and raj is S, M, R respectively

LCM of 30, 15 = 30

Let the work be 30 units.

According to the question-

R = 30 ÷ 30 = 1 unit/day

S + M = 30 ÷ 15 = 2 unit/day (Equation 1)

Since Sonu can complete the work at the same time as Manu and Raj combined-

S = M + R

⇒ S - M = R

S - M = 1 units/day (Equation 2)

Subtracting Equation 1 from Equation 2, we have- 

⇒ 2 × M = 1

M = $1\over2$

⇒ Time required by Manu to complete the work = $30\over {1\over2}$ = 30 × $2\over1$ = 60 days

∴ Manu needs 60 days to complete the work.

Formula:

P = $SP-CP\over CP$ × 100,

L = $CP-SP\over CP$ × 100, where

CP = Cost price

SP = Selling price

P = Profit %

L = Loss %

Calculations: 

Cost price of one orange = 50 ÷ 10 = Rs 5

Selling price of one orange = 24 ÷ 6 = Rs 4

Since SP > CP, this is a case of loss transaction-

⇒ L =  $5-4\over 5$ × 100 = $1\over5$ × 100 = 20%

∴ The loss percentage in the transaction is 20%.

Shortcut TrickCross multiplication

∴ The loss percentage is 20%

Given:

Normal speed of the student = 5 km/h.

Increased speed = 6 km/h

Time = 20 Minutes less

Formula:

D = S × T, where

D = Distance covered

S = Speed

T = Time 

Calculations:

Let the Distance be "D"

According to the question-

⇒ Time taken under normal speed = $D\over5$ hr

⇒ Time taken under increased speed = $D\over6$ hr

It is given that - 

⇒ $D\over5$ - $D\over6$ = $20\over60$

⇒ D($6-5\over30$) = $1\over3$ 

Solving for D, we get D = 10 km

∴ The distance covered by the student is 10 km.

Shortcut TrickDistance = $\frac{product \ of \ speed }{difference \ of \ speed}× difference \ of \ time$[time in hr]

Distance = $\frac{6\ × \ 5}{1}× \frac{20}{60}$ = 2 × 5 = 10 km

Formula:

SP = MP - $D\over100$ × MP, where

MP = Marked price

SP = Selling Price

D = Effective discount rate

Calculated:

Substituting the values, in the SP formula, we get-

⇒ SP = ₹350 - $10\over100$ × 350 = ₹ 350 - ₹ 35 = ₹ 315

∴ The selling price of the article is ₹ 315

Formula:

Efficiency = Total time taken to complete the task ÷ Time taken to complete the task individually. 

Calculation:

LCM of 60, 10, 35 = 420

Let the work be 420 units.

According to the question-

Efficiency of Ram = 420 ÷ 60 = 7 units/day

Total work done in 10 day by Ram = 7 × 10 = 70 units

Remaining work = 420 - 70 = 350 units

Efficiency of Raj = 350 ÷ 35 = 10 units/day

Combined efficiency of Ram and Raj = 7 + 10 = 17 units/day

Time required by both to complete the work together = $420\over17$ = 24$12\over17$ days.

∴ The time required by both to complete the work together is 24$12\over17$ days.

Calculation:

Total students = 40 + 5 = 45

Let the average expenditure be Rs "a".

New expenditure of the mess = 40a + 48

According to the question-

⇒ $40a + 48\over45$ - a = -2

⇒ 40a + 48 - 45a = -2 × 45

⇒ 48 - 5a = -90

⇒ 48 + 90 = 5a

⇒ a = $138\over5$ = Rs 27.6

∴ Original expenditure of the mess = Rs 27.6 × 40 = Rs 1,104

The original expenditure of the mess is Rs 1,104.

Formula:

L = CP - SP, where

SP = Selling Price

CP = Cost Price

L = Loss

Calculation:

Let the cost price of balls be "a".

Cost price of 56 balls = 56a

According to the question-

⇒ 56a - 3570 = 14a

⇒ 56a - 14a = 3570

⇒ 42a = 3570

⇒ a = 3570 ÷ 42 = 85

∴ Cost price of one ball is Rs 85.

Formula:

SI = $P \times R \times T \over 100$

SI = A - P

Where- 

A = Amount

P = Principal amount

R = Rate

T = Time

SI = Simple Interest

Calculation :

From the values given in the question-

SI = Rs 7,550 - Rs 5000 = Rs 2550

Substituting the values, to find "r"

⇒ 2550 = $5000 \times R \times 6 \over 100$

⇒ R = 8.5%

New rate of interest = 8.5% + 3.5% = 12%

⇒ SI = $5000 \times 12 \times 6 \over 100$ = Rs 3600

⇒ A = Rs 5000 + Rs 3600 = Rs 8600

The amount is Rs 8600.
