Sum of present ages = 66 + (7 × 2) = 80 years.

Total ratio parts = 5 + 3 = 8 units.

8 units = 80 years → 1 unit = 10 years.

Gitika's present age = 3 × 10 = 30 years.

∴ The correct answer is 30 years.

Alternate Method

Given: Ratio of present ages of Gauravi and Gitika = 5 : 3.

Calculation:

⇒ Let the present ages be 5x and 3x.

⇒ Sum of ages 7 years ago = (5x − 7) + (3x − 7) = 66

⇒ 8x − 14 = 66

⇒ 8x = 80

⇒ x = 10

⇒ Gitika's present age = 3x = 3 × 10 = 30 years.

∴ The correct answer is 30 years.

Ratio of Profit = (Capital₁ × Time₁) : (Capital₂ × Time₂)

Given: Raman (C₁=8000, T₁=12) and Lakhan (C₂=x, T₂=9).

Profit Ratio = (8000 × 12) : (x × 9) = 32 : 21.

Simplifying: 96000 : 9x = 32 : 21 ⇒ 96000 ÷ 9x = 32 ÷ 21.

x = (96000 × 21) ÷ (32 × 9) = 3000 × 7 ÷ 3 = 7000.

∴ The correct answer is Rs. 7000.

Alternate Method

Given → Raman Capital = Rs. 8000, Raman Time = 12 months, Lakhan Time = (12 − 3) = 9 months, Profit Ratio = 32 : 21. Formulas: Profit = Capital × Time | Capital = Profit ÷ Time

⇒ Let Lakhan contribution be x. ⇒ Profit of Raman = 8000 × 12 = 96000 units. ⇒ Profit of Lakhan = x × 9 = 9x units. ⇒ 96000 ÷ 9x = 32 ÷ 21. ⇒ 32 × 9x = 96000 × 21. ⇒ 288x = 2016000. ⇒ x = 2016000 ÷ 288 = 7000.

∴ The correct answer is Rs. 7000.

Time taken to catch = Distance ÷ Relative Speed.

Time = 50 ÷ 25 = 2 hr.

∴ The correct answer is 2 hr.

Alternate Method

Given:

Speed of Fast Car (S₁) = 60 km/hr

Speed of Slow Car (S₂) = 35 km/hr

Initial Distance (D) = 50 km

Formula Used:

Relative Speed (Same Direction) = S₁ − S₂

Time = Distance ÷ Relative Speed

Calculations:

⇒ Relative Speed = 60 km/hr − 35 km/hr = 25 km/hr

⇒ Time taken = 50 km ÷ 25 km/hr

⇒ Time taken = 2 hr

∴ The correct answer is 2 hr.

⇒ Total marks (A + B + C) = 45 × 3 = 135 --- (Eq 1)

⇒ Total marks (B + C + D) = 40 × 3 = 120 --- (Eq 2)

⇒ Subtracting Eq 2 from Eq 1: (A + B + C) − (B + C + D) = 135 − 120

⇒ A − D = 15 --- (Eq 3)

⇒ Given: A + D = 75 --- (Eq 4)

⇒ Adding Eq 3 and Eq 4: 2A = 90

⇒ A = 90 ÷ 2 = 45

∴ The correct answer is 45 marks.

Combined efficiency of 2(A + B + C) = Efficiency(A+B) + Efficiency(B+C) + Efficiency(A+C)

Total Work = LCM(18, 24, 36) = 72 units.

Efficiencies: (A+B) = 4, (B+C) = 3, (A+C) = 2. Sum = 9 units.

Efficiency of (A+B+C) = 9 ÷ 2 = 4.5 units.

Time taken = 72 ÷ 4.5 = 16 days.

∴ The correct answer is 16 days.

Alternate Method

Given: Time taken by (A + B) = 18 days, (B + C) = 24 days, and (A + C) = 36 days.

Formula Used: Efficiency = Total Work ÷ Time Taken

⇒ Adding the efficiencies: (A + B) + (B + C) + (A + C) = 4 + 3 + 2

⇒ 2(A + B + C) = 9

⇒ Efficiency of (A + B + C) = 9/2 = 4.5

⇒ Time taken by (A + B + C) = Total Work ÷ Efficiency

⇒ Time = 72 ÷ 4.5 = 16 days

∴ The correct answer is 16 days.

Additional Information

Work and Efficiency Relationship

Efficiency is inversely proportional to the time taken to complete the work. If time increases, efficiency decreases.

Initial Ratio (W:M) = 3 : 2 (Total = 5 units) | Final Ratio (W:M) = 1 : 2 (Total = 3 units)

Since only Milk is added, Water remains constant. Make Water units same: (3:2) and (1:2)×3 → (3:2) and (3:6).

Milk increase = 6 − 2 = 4 units. This 4 units = 5 liters replaced. So, 1 unit = 1.25 liters.

Total capacity = 3 + 6 = 9 units = 9 × 1.25 = 11.25 liters. Initial Milk = (2/5) × 11.25 = 4.5 liters.

∴ The correct answer is 4.5 liters.

Alternate Method

Given: Initial ratio Water : Milk = 3 : 2. Replaced volume = 5 liters. Final ratio = 1 : 2.

Formula Used: Quantity of liquid = Total volume × (Ratio part / Total parts)

⇒ Let total initial volume be 5x. Water = 3x, Milk = 2x.

⇒ After removing 5L: Water = 3x − 5×(3/5) = 3x − 3; Milk = 2x − 5×(2/5) = 2x − 2.

⇒ Adding 5L pure Milk: New Milk = 2x − 2 + 5 = 2x + 3.

⇒ New Ratio: (3x − 3) / (2x + 3) = 1 / 2

⇒ 2(3x − 3) = 1(2x + 3) ⇒ 6x − 6 = 2x + 3 ⇒ 4x = 9 ⇒ x = 2.25.

⇒ Initial Milk = 2x = 2 × 2.25 = 4.5 liters.

∴ The correct answer is 4.5 liters.

Distance covered by Bus in (20 − 16) minutes = Distance covered by Man in 16 minutes.

Ratio of Time taken for same distance (Bus : Man) = 4 : 16 = 1 : 4.

Ratio of Speed (Bus : Man) = 4 : 1.

Since Bus speed is 40 km/hr (4 units), Man speed (1 unit) = 40 ÷ 4 = 10 km/hr.

∴ The correct answer is 10 km/hr.

Alternate Method

Given: Speed of Bus (S_b) = 40 km/hr, Time interval of buses (T₁) = 20 min, Meeting interval (T₂) = 16 min.

Formula Used: S_b × (T₁ − T₂) = S_m × T₂

⇒ Distance between two consecutive buses = Speed × Time = 40 × (20/60) km.

⇒ When man moves towards terminal, Relative Speed = (S_b + S_m).

⇒ Distance = Relative Speed × Meeting Time

⇒ 40 × 20 = (40 + S_m) × 16

⇒ 800 = 640 + 16 × S_m

⇒ 16 × S_m = 160

⇒ S_m = 10 km/hr.

∴ The correct answer is 10 km/hr.

Given: M > C < D = R ≤ E < A ≥ V > Y

I. R < A → True (as R ≤ E < A)

II. M < E → False (as M > C < D = R ≤ E; thus a clear relation between M and E cannot be established).

III. D ≤ E → True (as D = R ≤ E)

Hence, conclusion I and III are true.

Given:

A ≥ B > C; C ≤ D ≤ E < F

On Combining:

A ≥ B > C ≤ D ≤ E < F

Conclusions:

I. A ≥ E→ False (as A ≥ B > C ≤ D ≤ E; therefore, the relationship between A and E cannot be determined)

II. C < F→ True (as C ≤ D ≤ E < F; therefore C < F)

Hence, only conclusion II is true.

Given statements: C ≥ F; B < C > D < H = I

On combining, we get

B < C ≥ F; I = H > D < C ≥ F

Conclusions:

I. I > F → False (As I = H > D < C ≥ F, thus, the relation between I and F cannot be determined)

II. H > C → False (As H > D < C, thus, the relation between H and C cannot be determined)

Hence, none of the conclusions is true
