Additional Information 

Types of Renewable Energy

Solar Energy:

• ​The radiant light and heat energy from the sun is harnessed with the use of solar collectors.
• These solar collectors are of various types such as photovoltaics, concentrator photovoltaics, solar heating, (CSP) concentrated solar power, artificial photosynthesis, and solar architecture.
• This collected solar energy is then used to provide light, heat, and different other forms of electricity.

Wind Energy:

• The energy we get from winds is known as wind energy.
• For this, windmills have been used for hundreds of years to pump out water from the ground. We use large tall wind turbines that allow winds to generate electricity.
• The natural airflow on the surface of the earth is used to run the wind turbines.
• The most preferred locations for these wind turbines to be installed are the areas which and strong and have constant airflows on offshore and sites that are at high altitudes.

Hydroelectricity:

• According to statistics, hydroelectricity generated around 16.6% of the global energy resources and constituted about 70% of all the renewable electricity.
• This energy is another alternative source of energy that is generated by the construction of dams and reservoirs on the flowing water, the kinetic energy from the flowing water is used to run the turbines which generate electricity.
• Tidal power converts the energy of tides and Wave power which captures the energy from the surface of the ocean waves for power generation.
• These two forms of hydropower also have huge potential in electric power generation

Geothermal Energy:

• It is the energy that is generated from the thermal energy which is stored in the earth.
• The heat energy is captured on sources such as hot springs and volcanoes and this heat is directly used by industries for heating the water and other purposes.

Bio-Energy:

• This type of energy is derived from biomass which is a type of biological material derived from living organisms and plant-derived materials which are called lignocellulosic biomass.
• Biomass can be directly used via combustion to produce heat and indirectly it can be used to convert to biofuels.
• Biomass can be converted to other usable forms of energy such as transportation fuels like ethanol, biodiesel, and methane gas.

Therefore Tin and Copper are shown individually but inside a common circle.

Hence, option 2 is the correct answer.

The mirror image of the question figure is given below:

Hence, option 4 is the correct answer.

CONCEPT :

Types of figure generally given in the exams.

The clearly seen alternate position of the open dice becomes the opposite pair after folding and the two remaining faces also become opposite to each other.

Here, In every figure:

A is opposite to C.

B is opposite to D.

Thus the remaining, E is opposite to F.

Important Points

The opposite pair of faces will never appear in the adjacent position of a dice. 

EXPLANATION :

The alternate position of faces becomes opposite to each other, as shown below:

The opposite pairs are (1, 3), (2, 4) and the remaining ( 5, 6).

The face opposite to the face having the number 5 is 6.

CONCLUSION :

Hence, option 3 is the correct answer.

The logic followed here is:

Hence, 98 is the correct answer.

This question shows that Ear, Nose and Eye part of the face but Throat is not part of face.

So, Throat is different from others.

Hence, option 4 is the correct answer.

Given that 

A takes 30 days to complete the work.

one day work of A = 1/30

B takes 15 days to complete the work.

one day work of B = 1/15

work done by ( A + B ) in one day = (1/30) + (1/15)

= (1 + 2) / 30

= 3/30

= 1/10

work done by ( A + B ) in one day = 1/10

Total work (1 unit ) will be completed by ( A + B) = 10 days

Hence, 10 will be the correct answer.

Alternate Method

 

Work / efficiency method

(A + B) takes = 30/ (1+2)

(A + B) takes =  30/3

(A + B) takes= 10 days

In option 1, 2 and 4 square is diagonally opposite to each other but in option 3 square is not diagonally opposite to each other.

This figure is different from other

Hence, option 3 is the correct answer.

When the folded paper is opened, the cuts will appear as follows:

Hence, the figure in option 1 is the correct answer.

The logic followed here is:

All the symbols of first figure are shifted to its adjacent box in anticlockwise direction to get the second figure.

Similarly, the third figure's symbols will also shifted to its adjacent box in anticlockwise direction to get the fourth figure.

Hence, the figure in option 4 is the correct answer.

• The second figure is the water image of the first figure.

• Similarly, the fourth figure is the water image of the third figure.

Hence, the figure in option 1 is the correct answer.

The logic followed here is:

Decoding the information, 

 

16 @ 26 $ 8 & 14 # 7

Putting the value of symbol

= 16 - 26 + 8 × 14 ÷ 7

After applying BODMAS

= 16 - 26 + 8 × 2

= 16 - 26 + 16

= 32 - 26

= 6

Hence, Option 1 is the correct answer.

Concept:

when any two faces are common in any two cubes then the remaining faces of that cube become opposite to each other.

From figure (i) and (ii) The face 2 and 3 are common, therefore the remaining 4 and 6 become opposite to each other.

The opposite of 4 is 6.

Hence, 6 is the correct answer.

In this question set (1, 2, 3) is given which is related to the option 3 which is multiple of 11 with the set (1, 2, 3) i.e. (11, 22, 33)

Hence, option 3 is the correct answer.

The diagram given bellow

The best relation of the figure is Girls, Students, Daughters.

All daughters are Girls and some Girls and Daughter are Students.

Hence, option 2 is the correct answer.

The pattern followed here is:

Triangle and Inverted V symbol shifted its position by 90 in the clockwise direction in each step.

Hence, the figure in option 2 is the correct answer.

The figure that is embedded in the question figure is the option ‘2’ figure.

Hence, option (2) is the correct answer.

The figure that is embedded in the question figure is the option ‘3’ figure.

Hence, option (3) is the correct answer.

Mistake Points

Option 1 and option 3 also satisfy the given condition but we need to eliminate them because of the size configuration, Option 1 has a bigger version.

As it is a previous year paper the acceptable answer given by the exam board is option 3.

When the question figure is merged with the figure in option 1, the complete pattern can be seen as:

Hence, figure in option (1) is the correct answer.

'Runway' is related to 'Airplane'. It means Airplane runs on Runway.

In the same way Athlete runs on Track.

So, Track related to Athlete.

Hence, option 1 is the correct answer.

The second number is related to the first number and the sixth number related to the fifth number. 168 : 8 :: 84 : ? :: 105 : 5

Second number is multiplied by 21 we get first number. Sixth number is multiplied by 21 we get fifth number. 

Similarly, fourth number is multiplied by 21 we get third number 

X × 21 = 84

X = $84 \over 21$

X = 4

Hence, option 3 is the correct answer.

The pattern followed here is:

Hence, 273 is the correct answer.

Concept Used:

Follow the BODMAS rule according to the table given below:

Calculation:

 $\frac{8}{3}\div\frac{3}{4}$ of $\frac{5}{6} + \frac{4}{9} \div \left( {\frac{3}{5} - \frac{1}{2}} \right) \times \frac{9}{{25}} + \frac{3}{5} \times \frac{4}{9} - \frac{4}{9} \div \frac{2}{3}$

⇒ 8/3 ÷ (3/4 × 5/6) + 4/9 ÷ (3/5 - 1/2) × 9/25 + 3/5 × 4/9 - 4/9 ÷ 2/3

⇒ 8/3 ÷ 5/8 + 4/9 ÷ 1/10 × 9/25 + 4/15 - 2/3

⇒ 8/3 × 8/5 + 4/9 × 10 × 9/25 + 4/15 - 2/3

⇒ 64/15 + 8/5 + 4/15 - 2/3

⇒ (64 + 24 + 4 - 10)/15

⇒ 82/15

∴ Required value is 82/15.

Given:

The sum of 2% of P and 2% of Q is two - third of the sum of 2% of P and 6% of Q

Calculation:

2% of P = 2P/100

2% of Q = 2Q/100

6% of Q = 6Q/100

Accordingly,

2P/100 + 2Q/100 = 2/3 × (2P/100 + 6Q/100)

⇒ 2P + 2Q = 2/3 × (2P + 6Q)

⇒ 2P + 2Q = 4P/3 + 4Q

⇒ 2P/3 = 2Q

⇒ P/Q = 3/1

⇒ P/3 = Q/1 = k (Say, k is a constant)

⇒ P = 3k and Q = k

2P : 5Q = 2 × 3k : 5 × k = 6k : 5k = 6 : 5

∴ 2P : 5Q = 6 : 5

Given:

The area of the 2nd square is 5 times the area of another square with a diagonal of 4√2 cm

Formula:

Diagonal of a square = √2a

Area of a square = a² 

⇒ (√2a)²/2 = (diagonal)²/2

Where, a = side of a square

Calculation:

Let, the area of 1st square is A₁ and that of the 2nd square is A₂

According to the question,

A₂ = 5A₁

⇒ (diagonal)²/2 = 5 × [(4√2)²]/2

⇒ (diagonal)²/2 = 80

⇒ Diagonal = 4√10 cm

∴ Diagonal of a square is 4√10 cm.

Given:

Rainfall = 4 cm

Volume of water = 1.5 hectares

Concept Used:

1 hectares = 10,000 m²

Volume = Area × Depth

Calculation:

1.5 hectares = 15000 m²

Depth = 4cm = 1/25 m

Volume = Area × Depth

⇒ Volume = 15000 × (1/25) = 600

∴ The volume of the water that falls on 1.5 hectares of ground is 600 m³.

Formula Used:

Average = Sum of terms/Number of terms

Calculation:

Three digits numbers having all digits same = 111, 222, 333, 444, 555, 666, 777, 888 and 999

The number of three-digit numbers having all digits the same = 9

Total sum of 9 numbers = 111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999 = 4995

∴ Required average = 4995/9 = 555

Hence, the correct answer is 555.

Given:

300 people worked for 60 days and completed half of the work. Next 100 people worked for 120days.

Total time 300 days

Concept Used:

Total Work = Time × Number of people

Calculation:

300 people in 60 days = 1/2 work

Let one people 1 day's work be a.

Total work done by 300 people in 60 days = 300a × 60

Accordingly,

300a × 60 = 1/2

⇒ a = 1/36000

100 people's 120 days work = 100a × 120 = 100/36000 × 120 = 1/3

Total work done = 1/2 + 1/3 = 5/6

Remaining work = 1 - 5/6 = 1/6

Remaining time = 300 - (60 + 120 + 20) = 100 days

Then,

Let remaining work done by n people.

⇒ 1/6 = n/36000 × 100

⇒ n = 60

∴ 60 people required to complete remaining work.

Given:

Average speed without stoppage = 75kmph

Average speed with stoppage = 60kmph

Distance = 600km

Calculation:

Time taken by the train to move without stoppage = 600/75

⇒ 8 hours

Time taken by the train to move with stoppage = 600/60

⇒ 10 hours

Train remains static for = 10 - 8 = 2 hours

∴ Total time taken by train for stoppages = 2 hours

Given:

The person spent 65% of his income on purchasing and the rest is his savings.

Concept Used:

The concept of percentage is calculated on the basis of 100.

For example, x% means x out of 100

Income = Savings + Expenditure

Calculation:

Let the person's income be Rs.A.

The total amount he spent on purchasing A and B = 1800 + 3270 = Rs.5070

Then, according to the question,

A × 65% = 5070

A × 65/100 = 5070

⇒ A = 7800

Now, his savings = Income - Expenditure

⇒ 7800 - 5070 = Rs.2730

Hence, the correct answer is Rs. 2730

Formula Used:

Simple interest = PRT/100

Compound interest = P(1 + R/100)^T - P

Where, P = Principle, R = rate of interest, and T = time

Calculation:

Simple interest = (24000 × 2 × 8)/100

⇒ 240 × 2 × 8

⇒ 480 × 8 = Rs.3840

Compound interest = 24000(1 + 5/100)² - 24000

⇒ 24000(1 + 1/20)2 - 24000

⇒ 24000(21/20)2 - 24000

⇒ 24000(441/400) - 24000

⇒ 441 × 60 - 24000

⇒ 26460 - 24000 = Rs.2460

The ratio of interest from A to B is 3840 : 2460 = 64 : 41

∴ The required ratio is 64 : 41

Calculation:

Number of rows = 9, 10 and 15.

LCM = 9, 10 and 15

⇒ 9 = 3 × 3

⇒ 10 = 5 × 2

⇒ 15 = 3 × 5

LCM = 2 × 3 × 3 × 5 = 90

There are two 3 which gives a square of 3 but only one 2 and one 5 so, to get a perfect square number we have to multiply 90 by 2 and 5

The perfect square is 90 × 2 × 5 = 900

∴ The required number of least marbles is 900

Given:

He purchased at the rate 8 pens for Rs. 24 and sells at the rate of 9 pens for Rs. 45

Total gain in transaction Rs. 240

Formula:

Profit = SP - CP

Calculation:

Let the number of pens in a box be n.

Cost price of a pen = 24/8 = Rs.3

Selling price of pen = 45/9 = Rs.5

⇒ 5n - 3n = 240

⇒ n = 120

∴ Number of pens contain in the box is 120.

Formula Used:

SP = CP × (100 + profit%)/100

Calculation:

Let the cost price of the article be Rs.100.

Selling price = 100 × 125/100 = Rs.125

Marked price = 125 × 100/80 = Rs.156.25

New cost price = 100 × 110/100 = Rs.110

Profit to be earn = 125 - 100 = Rs.25

Profit % = 25/100 × 100 = 25%

Selling price = 110 × 125/100 = Rs.137.5

Let the discount given be a%

⇒ 137.5 = 156.25 × (100 - a)/100

⇒ a = 12

∴ He should give a 12% discount on the increased cost price.

Alternate Method 

Given: 

A dealer who allows a 20% discount on MP still gains 25% profit

Now, CP increased by 10% but the dealer still wants to earn 25% profit on the CP

Concept Used:

$CP \over MP$=

$100 - Disount \over 100 + Profit$

**Formula Used:**Percentage Increase or Decrease = Original Value × $100 \pm percentage change \over 100$

Calculation:

CP : MP = $100-20 \over 100+25$

⇒ CP : MP = $80 units \over 125 units$

Now, the CP is increased by 10%

⇒ new CP = 80 × $110 \over 100$

⇒ new CP = 88 units

Now, from the given, the dealer wants to earn 25% profit on the new CP

⇒ new SP = 88 × $125 \over 100$

⇒ new SP = 110 units

But MP is the same as earlier which is 125 units

So, the dealer could offer a discount of 15 units on 125 units

⇒ % Discount = $15 \over 125$× 100

⇒ % Discount = 12%

∴ The dealer should allow a 12% discount on the MP so as to earn the same profit as before.

Formula Used:

Simple Interest = PRT/100

Where, P = Principle, R = rate of interest and T = time

Calculation:

Let the amount invested at 15% be Rs.a

Simple interest at rate 15% = a × 15 × 2/100 = Rs.30a/100

Simple interest at rate 18% = (50000 - a) × 18 × 2/100 = Rs.(1800000 - 36a)/100

⇒ 30a/100 + (1800000 - 36a)/100 = 16800

⇒ 30a/100 + 18000 - 36a/100 = 16800

⇒ 1200 = 6a/100 ⇒ 200 = a/100

⇒ a = 20000

The sum invested at 15% rate = Rs.20000

Sum invested at 18% rate = 50000 - 20000 = Rs.30000

∴ Required ratio = 20000 : 30000 = 2 : 3

 

Rate of interest are 15% and 18%

Principal (P) = 50000

Time (T) = 2 years

Overall interest gain of 16800

Let, the overall rate of interest is R%

Then,

(50000 × R × 2)/100 = 16800

⇒ R = 16.8

Now, by applying allegation, we can obtain the ratio of investment

The ratio of the amount in part 1 and part 2 is 1.2 : 1.8 = 2 : 3

∴ The required ratio is 2 : 3

Shortcut Trick

Savings %: A = 30%, B = 20%, C = 8%.

Income Ratio = (Savings Ratio ÷ Savings %)

Income Ratio = (15/30%) : (11/20%) : (10/8%) = 50 : 55 : 125 = 10 : 11 : 25.

Total units = 10 + 11 + 25 = 46 units → ₹69,000. 1 unit = ₹1,500.

B Savings = Savings Ratio Part × Unit Value = 11 × 1500 × 20% = ₹3,300.

∴ The correct answer is ₹3,300.

Alternate Method

Given: Total Income = ₹69,000. Expenditure: A=70%, B=80%, C=92%. Savings Ratio = 15 : 11 : 10.

Formula: Income = Savings / Savings%

⇒ Savings % of A = 100% − 70% = 30%

⇒ Savings % of B = 100% − 80% = 20%

⇒ Savings % of C = 100% − 92% = 8%

⇒ Ratio of Incomes (A:B:C) = (15/30) : (11/20) : (10/8)

⇒ Ratio of Incomes = (1/2) : (11/20) : (5/4)

⇒ Multiplying by LCM (20): 10 : 11 : 25

⇒ Total Income = (10 + 11 + 25)k = 46k = 69,000

⇒ k = 69,000 / 46 = 1,500

⇒ Income of B = 11 × 1,500 = ₹16,500

⇒ Monthly savings of B = 20% of 16,500 = 0.20 × 16,500 = ₹3,300

∴ The correct answer is ₹3,300.

Additional Information

Income, Expenditure and Savings

Income = Expenditure + Savings. If expenditure is x%, then savings is (100−x)% of income.

Ratio Conversion

To convert a fractional ratio to a linear ratio, multiply all terms by the LCM of the denominators.

Percentage to Ratio

Income of a person can be found if Savings and Saving% are known: Income = (Savings / Saving%) × 100.

Given:

The difference between a two-digit number and the number obtained by interchanging the position of its digit is 45.

Concept Used:

If the 10th place digit of a number is a and the unit place digit is b then the number will be (10a + b)

Calculation:

Let the number be 10a + b.

Two digit number after interchanging the position of the digits = 10b + a

According to the question,

10a + b - 10b - a = 45

⇒ 9a - 9b = 45

⇒ a - b = 5

The difference between a two-digit number is 5.

Such possible pairs are (1, 6); (2, 7); (3, 8), and (4, 9)

∴ The difference between two digits is 5 and there are 4 possible numbers.
