• In Active Voice, a sentence emphasizes the subject, performing an action.
• In Passive Voice, a sentence emphasizes the action or the object of the sentence.
• The given sentence is in the passive voice and it is in the present perfect tense.
• When we convert this sentence into an active voice, the subject 'all the bills' of the passive voice becomes the object, the object 'someone' becomes the subject.
• The passive format "have + been + V3 (verified)" should be converted into the active format "has + V3 (verified)".
• This is the active and passive voice rule for the present perfect tense.

Hence, the correct answer is option 1.

Additional Information

Shortcut Trick

Apply the Chain Rule formula: M₁ × D₁ = M₂ × D₂

34 × 12 = 51 × D₂

D₂ = (34 × 12) ÷ 51 = 2 × 4 = 8 days.

∴ The correct answer is 8 days.

Alternate Method

Given:

Initial Men (M₁) = 34

Initial Days (D₁) = 12

Final Men (M₂) = 51

Formula Used:

Total Work = Men × Days

Calculations:

⇒ Total Work = 34 × 12 = 408 units

⇒ Required Days (D₂) = Total Work ÷ M₂

⇒ D₂ = 408 ÷ 51

⇒ D₂ = 8 days

∴ The correct answer is 8 days.

Additional Information

Man-Day Concept

The amount of work is proportional to the number of men and the time taken. If work (W) is constant, then M₁D₁ = M₂D₂.

General Chain Rule

For different work amounts and hours: (M₁ × D₁ × H₁) ÷ W₁ = (M₂ × D₂ × H₂) ÷ W₂.

Inverse Variation

Men and Days are in inverse variation; as the number of workers increases, the time required to finish the work decreases.

The correct answer is Chlorine.

Key Points

• Chlorine kills pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules.
• Disinfectants that are used for this purpose consist of chlorine compounds which can exchange atoms with other compounds, such as enzymes in bacteria and other cells.
• When enzymes come in contact with chlorine, one or more of the hydrogen atoms in the molecule are replaced by chlorine.
• This causes the entire molecule to change shape or fall apart.
• When enzymes do not function properly, a cell or bacterium will die.
• Chlorine effectively kills a large variety of microbial waterborne pathogens, including those that can cause typhoid fever, dysentery, cholera and Legionnaires' disease.

Additional Information

• Bromine is a chemical element with the symbol Br and atomic number 35. Bromine is used in many areas such as agricultural chemicals, dyestuffs, insecticides, pharmaceuticals and chemical intermediates.
• Iodine is an essential mineral commonly found in seafood.
• A colourless, odourless gas Nitrogen is important to the chemical industry.
• It is used to make fertilisers, nitric acid, nylon, dyes and explosives.
• To make these products, nitrogen must first be reacted with hydrogen to produce ammonia.

The correct answer is- '(B).'

Key Points

• The error lies in Part (B) of the sentence.
• Countable nouns, as the term suggests, refer to things that can be counted.
• They have singular and plural forms.
• Example: table, tables; month, months; pen, pens, etc.
• Uncountable nouns cannot be counted.
• They have a singular form and do not have a plural form.
• Example: dirt, rice, information, furniture, charity, hair, time, etc.
• Therefore, the use of 'times' should be replaced by 'time' to make it grammatically correct.
• Hence, the correct answer is '(B).'
• Correct sentence: Have you got time for a cup of coffee?

Additional Information 

• Countable nouns, as the term suggests, refer to things that can be counted.

• Uncountable nouns की गणना नहीं की जा सकती।
• उनका singular रूप है और plural रूप नहीं है।
• Example: dirt, rice, information, furniture, charity, hair, etc.
• इसलिए वाक्य में  'times' के प्रयोग को 'time' से बदल देना चाहिए ताकि वह व्याकरण की दृष्टि से सही हो।​

Shortcut Trick

Ratio of Profit X : Y : Z = (Capital × Time) ratio

X : Y : Z = (5 × 6 + 2.5 × 6) : (3 × 12) : (7 × 12)

X : Y : Z = 45 : 36 : 84 = 15 : 12 : 28

Total units = 15 + 12 + 28 = 55 units = ₹55,000 → 1 unit = ₹1,000

Profit Difference (X − Y) = 15 − 12 = 3 units

∴ Answer = 3000

Alternate Method 

Given:

Initial investment ratio X : Y : Z = 5 : 3 : 7

X withdraws half capital after 6 months. Total profit = ₹55,000. Time = 1 year.

Formula used:

Profit Share ∝ Capital × Time

 X (5 → 2.5)  Y (Cap: 3)  Z (Cap: 7) Time: 6+6m 12 months 12 months Profit Ratio = 15 : 12 : 28

Calculations:

Let initial capitals be 5k, 3k, and 7k.

⇒ X profit share = (5k × 6) + (2.5k × 6) = 30k + 15k = 45k

⇒ Y profit share = 3k × 12 = 36k

⇒ Z profit share = 7k × 12 = 84k

⇒ Ratio of Profit X : Y : Z = 45 : 36 : 84 = 15 : 12 : 28

⇒ Sum of ratio parts = 15 + 12 + 28 = 55 units

⇒ 55 units = ₹55,000 ⇒ 1 unit = ₹1,000

⇒ Difference between X and Y = (15 − 12) × 1,000 = ₹3,000

∴ The correct answer is option (3).

Additional Information

Profit Sharing Rule

In a partnership, profit is always distributed in the ratio of (Capital × Time Period). Formula: P₁:P₂ = C₁T₁ : C₂T₂.

Active vs Sleeping Partner

An active partner manages the business and may receive a salary or commission before the remaining profit is divided according to investment ratios.

Compound Partnership

When partners invest different capitals for different durations, it is a compound partnership where effective capital = Σ(Capital × Duration).
