Placing the eight friends according to the given clues yields the arrangement where A, X, B, and D occupy the middle of the sides facing inside, while C, Y, Z, and W occupy the corners facing outside. In clockwise order, the positions are A at top-middle, C at top-right corner, X at right-middle, Y at bottom-right corner, B at bottom-middle, Z at bottom-left corner, D at left-middle, and W at top-left corner. Since Z sits at a corner facing outside, left of Z corresponds to the counter-clockwise direction along positions occupied by B, Y, and X before reaching C. Thus, exactly three persons sit between Z and C when counted from the left of Z.

Answer: (C) if neither conclusion I nor II is true.

Explanation

Combining the statements for conclusion I gives K ≤ B ≤ L ≤ T ≤ I ≥ M < X. The inequality signs reverse direction at I, making it impossible to determine a definite relationship between K and X. For conclusion II, combining the statements gives W < P ≤ L ≤ T ≤ I ≥ M. The inequality signs again reverse direction at I, so no definite relationship can be established between W and M. Therefore, neither conclusion I nor II is true.

Explanation

Combining the relevant parts of the given statement yields Z < U ≤ D ≤ A ≤ Y < G. Since Z is strictly less than A and A is less than or equal to Y, it follows directly that Z < Y, making conclusion I true. For conclusion II, the statements give A < S and A < Q, which places both S and Q above A without defining a direct relation between S and Q. Therefore, conclusion II cannot be logically deduced.

Answer: (C) if neither conclusion I nor II is true.

Explanation

To evaluate conclusion I, combining the statements yields K ≤ B ≤ L ≤ T ≤ I ≥ M. The presence of opposing inequality signs at I means no direct comparison can be made between K and M. To evaluate conclusion II, combining the statements gives P ≤ L ≤ T ≤ I ≥ M. Due to the same reversal of inequality signs at I, no definite comparison exists between P and M. Hence, neither conclusion I nor II is true.

For conclusion II, the relevant segment is H = U ≥ B ≤ T < F ≤ R, where opposing inequality signs at B break the relationship chain between H and R. Thus, only conclusion I is true.

Answer: (B) Rs. 1500

Explanation

Simple Interest SI = (P × R × T) / 100 1950 = (P × 15 × 2) / 100 P = 1950 × 100 / 30 = Rs. 6500

For Scheme B, the effective compound interest rate for 2 years at 10% p.a. is 10 + 10 + (10 × 10)/100 = 21%. Compound Interest = 21% of (6500 + x) 1680 = 0.21 × (6500 + x) 6500 + x = 1680 / 0.21 = 8000 x = 8000 - 6500 = Rs. 1500

Answer: (B) 100%

Explanation

Let males in Haircutting be 13k and females in Haircutting be 7k. Males in Pedicure = 7k + 72. Total males = 13k + 7k + 72 = 20k + 72. Since Total males + Total females = 450 and Total males - Total females = 174: 2 × Total males = 624 ⇒ Total males = 312. 20k + 72 = 312 ⇒ 20k = 240 ⇒ k = 12.

Males in Haircutting = 13 × 12 = 156. Males in Pedicure = 7(12) + 72 = 156. Required percentage = (156 / 156) × 100 = 100%.

For equation (ii): 3y² - 5y + 2 = 0 Splitting the middle term: 3y² - 3y - 2y + 2 = 0 3y(y - 1) - 2(y - 1) = 0 (3y - 2)(y - 1) = 0 y = 0.67, 1

Since both roots of x are negative and both roots of y are positive, x < y.

Answer: (C) x > y

Explanation

For equation (i): 12x² + 11x + 2 = 0 Splitting the middle term: 12x² + 8x + 3x + 2 = 0 4x(3x + 2) + 1(3x + 2) = 0 (4x + 1)(3x + 2) = 0 x = -0.25, -0.67

For equation (ii): 2y² + 11y + 14 = 0 Splitting the middle term: 2y² + 4y + 7y + 14 = 0 2y(y + 2) + 7(y + 2) = 0 (2y + 7)(y + 2) = 0 y = -3.5, -2

Comparing the roots: -0.25 > -2, -0.25 > -3.5, -0.67 > -2, and -0.67 > -3.5. Therefore, x > y.

Answer: (B) x = y or no relation can be established between x & y

Explanation

(i) 12x² + 11x + 2 = 0 -> (3x+2)(4x+1) = 0 -> x = -2/3, -1/4 (ii) 12y² + 7y + 1 = 0 -> (3y+1)(4y+1) = 0 -> y = -1/3, -1/4

Comparing the root pairs: -2/3 < -1/3, -2/3 < -1/4, -1/4 > -1/3, and -1/4 = -1/4. The relationship is not consistent across pairs, so no definite relation can be established between x and y.

Answer: (B) x = y or no relation can be established between x and y

Explanation

For equation (i): 21x² + 10x + 1 = 0 Splitting the middle term: 21x² + 7x + 3x + 1 = 0 7x(3x + 1) + 1(3x + 1) = 0 (7x + 1)(3x + 1) = 0 x = -1/7 ≈ -0.143, -1/3 ≈ -0.333

For equation (ii): 24y² + 26y + 5 = 0 Splitting the middle term: 24y² + 20y + 6y + 5 = 0 4y(6y + 5) + 1(6y + 5) = 0 (4y + 1)(6y + 5) = 0 y = -1/4 = -0.25, -5/6 ≈ -0.833

Comparing the roots: -1/7 > -1/4 (-0.143 > -0.25) -1/3 < -1/4 (-0.333 < -0.25)

Since x is greater than y in one case and less than y in another, no definitive relation can be established between x and y.

87Quantitative Aptitude
'A' can complete a work in 20 days while B is 25% more efficient than 'A'. B worked for 6 days and left, remaining work is completed by 'C' in 15 days. Find in how many days 'C' can complete the whole work alone?

Answer: (D) 24 days

Explanation

Let the total work be 20 units. A completes 20 units in 20 days, so A's efficiency = 1 unit per day. Since B is 25% more efficient than A, B's efficiency = 1 + 0.25 = 1.25 units per day. Work completed by B in 6 days = 6 × 1.25 = 7.5 units. Remaining work = 20 - 7.5 = 12.5 units. C completes this 12.5 units in 15 days, so C's efficiency = 12.5 / 15 = 5/6 units per day. Time taken by C to complete the total 20 units alone = 20 / (5/6) = 24 days.

Answer: (B) 120km

Explanation

Total distance PR = 200 km. Total time for the journey = Total distance / Average speed = 200 / 75 = 8/3 hours. Let the distance between P and Q be d km. Then the distance between Q and R is (200 - d) km. Time taken from P to Q = d / 90 hours. Time taken from Q to R = (200 - d) / 60 hours. Total time equation: d / 90 + (200 - d) / 60 = 8/3 Multiplying both sides by 180: 2d + 3(200 - d) = 480 2d + 600 - 3d = 480 600 - d = 480 d = 120 km.

Show answer & explanationHide answer

Answer: (E) None of these

Explanation

Let the initial quantity of wine be 5x litres and water be 1x litres. When 5 litres of water is added, the new quantity of water becomes (x + 5) litres. Given ratio of wine to water: 5x / (x + 5) = 5 / 2 2 × 5x = 5(x + 5) 10x = 5x + 25 5x = 25 x = 5

Therefore, the initial quantity of wine in the mixture = 5x = 5 × 5 = 25 litres.

90Quantitative Aptitude
The average salary of the entire staff in an office is Rs 3200 per month. The average salary of officers is Rs 6800 and that of non- officers is Rs 2000. If the number of officers is 5, then find the number of non- officers in the office?

Show answer & explanationHide answer

Answer: (C) 15

Explanation

By the weighted average formula or the rule of alligation: Ratio of number of Officers to Non-officers = (Mean Salary - Non-officer Salary) / (Officer Salary - Mean Salary) Ratio = (3200 - 2000) / (6800 - 3200) = 1200 / 3600 = 1 / 3

Given that the number of officers is 5: Number of non-officers = 5 × 3 = 15.
