731 ÷ 13 + 450 – 25 × 43 = 142

After interchanging 13 and 43 and using BODMAS rule we get the following:

731 ÷ 43 + 450 – 25 × 13

= 17 + 450 – 25 × 13

= 17 + 450 – 325

= 467 – 325

= 142

Hence, the correct answer is '13 and 43'.

Given:

The batsman scored 84 runs in his 12^th innings, thereby improving his average score per innings by 4 runs.

Concept used:

Total = Average × Number of entities

Calculation:

Let the average of the batman in the first 11 innings be N.

The total run scored by the batsman in the first 11 innings = 11 × N = 11N

The total run scored by the batsman in all 12 innings = 11N + 84

New average score after 12^th innings = N + 4

According to the question,

(11N + 84)/12 = (N + 4)

⇒ (11N + 84) = (N + 4) × 12

⇒ 11N + 84 = 12N + 48

⇒ 12N - 11N = 84 - 48

⇒ N = 36

Now, N + 4 = 36 + 4

⇒ 40

∴ 40 is the average score per innings of the batsman after the 12^th innings.

The best course of action will be to inform the municipality of your locality about the illegal construction of your neighbour because this issue lies in their jurisdiction. If the municipal corporation fails to address the issue, police can be involved.

Fighting in person is not a logical or ethical solution to the problem.

There are preliminary steps like investigation and evidence collection involved in the process of arresting criminals of any kind. You should comply with the rules.

The higher administration like the Chief Minister's office should be involved only if the problem remains unsolved after taking all the necessary measures or in case of an emergency.

Hence, “option 2” should be the immediate course of action.

Given:

Swati's initial investment S = Rs. 4,200.

Bani joins after 5 months.

The profit ratio after a year is 2 ∶ 5 (Swati : Bani).

Formula Used:

The profit ratio is determined by the product of the investment amount and the time period for each partner.

Calculation:

Let Bani's investment be ( B ) Rs.

Swati's total investment time = 12 months.

Bani's total investment time = 12 - 5 = 7 months.

Swati's share in the profit = ( 4200 × 12 )

Bani's share in the profit = ( B × 7 )

The given profit ratio is:

\(( \frac{Swati's\ share}{Bani's\ share} = \frac{2}{5} )\)

\(( \frac{4200 × 12}{B × 7} = \frac{2}{5} )\)

( 4200 × 12 × 5 = 2 × B × 7 )

( 252000 = 14B )

B = 252000/14

( B = 18000 ) Rs.

Bani’s contribution is Rs. 18,000.

The correct answer is Kinetic Energy

Key Points

• Water stored in a reservoir at a high elevation has gravitational potential energy due to its height above the ground. When water is released, this potential energy is converted into kinetic energy as the water flows down through the penstocks (large pipelines).
• As water flows down, its potential energy is converted into kinetic energy—the energy of motion. This fast-moving water strikes the blades of a turbine, causing the turbine to spin.
• The turbine is connected to a generator. As the turbine spins, it turns the rotor of the generator, converting into electrical energy through electromagnetic induction.

Given:

The ratio of the side of a triangle = 8 ∶ 7 ∶ 9 

The perimeter of triangle = 144

Formula required:

The perimeter of triangle = sum of the sides of the triangle

Area of a triangle =\(√ {s(s - a)(s - b)(s - c)}\)

S = (a + b + c)/2

Where a,b, c are the sides of a triangle

Calculations:

S = (8x + 7x + 9x)/2

a + b + c = 144

S = 144/2

⇒ 72

24x = 144

⇒ x = 6

Hence, a = 8 × 6

⇒ 48cm

b = 7 × 6

⇒ 42cm

c = 9 × 6

⇒ 54cm

Area of a triangle = \(√{72(72 - 48)(72 - 42)(72 - 54)}\)

⇒ 432√5 cm²

From the statement, “during peak hours it is better to travel by a two-wheeler”, as we know that during peak hours there a lot of traffic jam and there is very little space to move and a two-wheeler require less space. Thus, we can assume that “a two-wheeler is easier to navigate in the traffic”.

Since in the statement it is not mentioned about “separate lane for two-wheelers” and separate lanes for two-wheels are not present in all cities.

Hence, “only assumption I is implicit”.

Given:

Ratio of father and son age = 8 : 3

Ratio after 4 years = 11 : 5

Calculations:

Let the age of Father and Son three years before "8a" and "3a"

Age of Father and Son after 4 years from 3 years past = (8a + 7) and (3a + 7)

According to the question-

⇒ \(8a+7\over 3a+7\) = \(11\over 5\)

⇒ 40a + 35 = 33a + 77 

⇒ 7a = 42

⇒ a = 6

∴ Present age of Father = (8a + 3) = 8 × 6 + 3 = 51 years

∴ the present age of Father is 51 years.

Shortcut TrickAge ratio three years ago = 8 : 3

Age ratio (4 + 3) i.e. 7 years after = 11 : 5

Let the common ratio be Q.

40Q - 33Q = 77 - 35

⇒ 7Q = 42

⇒ Q = 6

⇒ 8Q = 48

⇒ 8Q + 3 = 51

Now, the present age of father = 51 years

∴ The present age of the father is 51 years.

The correct answer is Bhopal.

Let the present age be P.

Equation: P + 12 = 3 × (P − 4)

P + 12 = 3P − 12

2P = 24 ⇒ P = 12

∴ The correct answer is 12 Years.

Alternate Method

Given:

Time into the future = 12 years

Time in the past = 4 years

Ratio of future age to past age = 3 : 1

Let age 4 years ago be x.

Age 12 years later = 3x

The difference between these two points in time = 12 + 4 = 16 years.

⇒ 3x − x = 16

⇒ 2x = 16

⇒ x = 8 years (Age 4 years ago)

⇒ Present Age = 8 + 4 = 12 years

∴ The correct answer is 12 Years.

Additional Information

Age Ratio Concepts

If the ratio of ages of two people is a:b, then after 'n' years, the ratio becomes (a+n):(b+n). The difference between ages always remains constant.

Future and Past Ages

If present age is 'x', age 'n' years ago is (x − n) and age 'm' years hence is (x + m). The total gap between these two periods is (n + m) years.

The correct answer is Thermal expansion.

Key Points

• Thermal expansion is NOT a chemical weathering process.
• Thermal expansion, which typically excludes phase transitions, is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature.
• The average molecular kinetic energy of a substance has a monotonic relationship with temperature. When something is heated, the molecules start to move and vibrate more, usually putting more space between them.
• Rarely, and only within certain temperature ranges, do substances contract as the temperature rises (see examples below).

Important Points

• Weathering by Chemical Rocks and soil undergoes chemical weathering, which modifies their molecular composition.
• For instance, a process known as carbonation occurs occasionally when water and carbon dioxide from the air or soil combine.
• This generates carbonic acid, a weak acid that can dissolve rock. Limestone can be easily dissolved by carbonic acid.

Additional Information

• Carbonation
• Carbonation is the process by which carbon dioxide is chemically transformed into carbonates, bicarbonates, and carbonic acid.
• Hydration
• A material that contains water or its component parts is referred to as a hydrate in chemistry.
• ​Oxidation
• A molecule, atom, or ion undergoes oxidation when it loses electrons as a result of a process.

the correct answer is Option 3.

Key Points

• Since its formation in 1994, the United Communist Party of Nepal (Maoists) has gone through a number of radical transformations, shifting from a guerrilla warfare unit to a key democratising force within Nepali politics.
• The party’s early history is defined by its role in launching the ‘people’s war’ of 1996, a decade-long civil war that resulted in the loss of some 16 000 lives and halted the country’s economic development. The Maoists’ original aim was to benefit the poor and marginalised sectors of Nepali society by uprooting the monarchy and feudalism.
• The Maoists have also achieved two other key victories. Following their entrance into peaceful politics in 2006, the Maoists gained the largest number of votes in the April 2008 Constituent Assembly election, winning 220 out of 575 elected seats. But their biggest achievement so far has been the overthrow of the monarchy in 2008. Many analysts maintain that the Maoist-initiated war sped up this outcome by at least a few decades.
• Yet the Maoists have failed to make progress on other key matters. Despite the impressive political developments, the Constituent Assembly failed to produce the new constitution it was originally tasked with writing, and its dissolution has left the country in a political and constitutional deadlock.
