Find the odd one out:
A)
35
B)
63
C)
54
D)
42
To find the odd one out, we examine the mathematical properties of the given numbers:
1. 35 is a multiple of 7 (7 x 5 = 35).
2. 63 is a multiple of 7 (7 x 9 = 63).
3. 42 is a multiple of 7 (7 x 6 = 42).
4. 54 is NOT a multiple of 7 (54 ÷ 7 = 7 with a remainder of 5).
Alternatively, looking at the pattern of (n^2 - 1):
- 35 = 6^2 - 1
- 63 = 8^2 - 1
- 42 does not fit this pattern, but 54 also does not.
However, the most consistent logical link between three of the four numbers is divisibility by 7. Since 35, 63, and 42 are all divisible by 7, while 54 is not, 54 is the odd one out.

A shopkeeper purchased 300 bulbs for Rs. 10 each. However, 20 bulbs were fused and had to be thrown away. The remaining were sold at Rs. 12 each. Find the gain or loss percent.
A)
10 % gain
B)
10 % loss
C)
12 % loss
D)
12 % gain
Total Cost Price (CP) = 300 bulbs × Rs 10 = Rs 3,000. Remaining usable bulbs = 300 - 20 = 280 bulbs. Total Selling Price (SP) = 280 × Rs 12 = Rs 3,360. Net Gain = Rs 3,360 - Rs 3,000 = Rs 360. Gain % = (360 / 3000) × 100 = 12% gain.

A)
20 years
B)
22 years
C)
24 years

In a certain code ‘POTASSIUM’ is written as ‘PoTassium’. How is ‘GRAPHITE’ written in that code?
A)
GrAphItE
B)
GrApHiTe
C)
gRaPHiTe
D)
GRAphiTE
To solve this coding-decoding problem, we must analyze the pattern of capitalization in the word 'POTASSIUM' as it transforms into 'PoTassium'.
1. Analyze the pattern in 'POTASSIUM' -> 'PoTassium':
- Position 1: P (Uppercase) -> P (Uppercase)
- Position 2: O (Uppercase) -> o (Lowercase)
- Position 3: T (Uppercase) -> T (Uppercase)
- Position 4: A (Uppercase) -> a (Lowercase)
- Position 5: S (Uppercase) -> s (Lowercase)
- Position 6: S (Uppercase) -> s (Lowercase)
- Position 7: I (Uppercase) -> i (Lowercase)
- Position 8: U (Uppercase) -> u (Lowercase)
- Position 9: M (Uppercase) -> m (Lowercase)
Wait, looking closer at the provided code 'PoTassium', the pattern is:
- 1st letter: Uppercase (P)
- 2nd letter: Lowercase (o)
- 3rd letter: Uppercase (T)
- 4th letter onwards: Lowercase (assium)
However, let's re-examine the options for 'GRAPHITE' to see if a consistent alternating pattern exists:
- Option (a) GrAphItE: Uppercase (G), Lowercase (r), Uppercase (A), Lowercase (p), Uppercase (H), Lowercase (i), Uppercase (T), Lowercase (e). This is a perfect alternating pattern (Upper, Lower, Upper, Lower...).
Let's re-evaluate 'PoTassium' with the alternating pattern:
- P (U), o (L), T (U), a (L), s (U), s (L), i (U), u (L), m (U) -> This would be 'PoTaSsIuM'.
Since the provided example 'PoTassium' only shows the first three letters following the alternating pattern (P-U, o-L, T-U) and then becomes lowercase, but the options for 'GRAPHITE' strongly suggest a full alternating pattern, we apply the alternating case logic (Uppercase for odd positions, Lowercase for even positions):
- G (1 - Odd): Uppercase
- R (2 - Even): Lowercase
- A (3 - Odd): Uppercase
- P (4 - Even): Lowercase
- H (5 - Odd): Uppercase
- I (6 - Even): Lowercase
- T (7 - Odd): Uppercase
- E (8 - Even): Lowercase
Result: GrAphItE. This matches Option (a).

Lala and Dova can do a piece of work in 45 days and 40 days respectively. They began the work together, but Lala leaves after 9 days. In how many days will Dova finish the remaining work?
A)
23 days
B)
21 days
C)
18 days
D)
16 days
Daily work done together = 1/45 + 1/40 = 17/360. In 9 days, Lala and Dova complete 9 * (17/360) = 153/360 = 17/40 of the work. The remaining work is 1 - 17/40 = 23/40. Dova completes this at rate 1/40 per day in (23/40) / (1/40) = 23 days.

If 40% of the students in a school are boys and the number of girls in the school is 540. How many boys are there in the school?
A)
360
B)
390
C)
420
D)
460
If 40% are boys, then 60% are girls. 60% of total students = 540 => Total students = 540 / 0.60 = 900. Number of boys = 40% of 900 = 360.

A bag contains 12 white balls and some green balls. If the probability of drawing a white ball from the bag is thrice that of the green ball. Find the number of green balls:
A)
10
B)
8
C)
6
D)
4
Step-by-step solution:
1. Let the number of white balls be W = 12.
2. Let the number of green balls be G (this is what we need to find).
3. The total number of balls in the bag is (12 + G).
4. The probability of drawing a white ball, P(White), is given by: P(White) = 12 / (12 + G).
5. The probability of drawing a green ball, P(Green), is given by: P(Green) = G / (12 + G).
6. According to the problem, the probability of drawing a white ball is thrice (3 times) that of the green ball. Therefore: P(White) = 3 * P(Green).
7. Substituting the values: 12 / (12 + G) = 3 * [G / (12 + G)].
8. Since the denominators are the same and cannot be zero, we can cancel them out: 12 = 3G.
9. Solving for G: G = 12 / 3 = 4.
Verification of options:
- If G = 10, P(W) = 12/22 and P(G) = 10/22. 12 is not 3 * 10.
- If G = 8, P(W) = 12/20 and P(G) = 8/20. 12 is not 3 * 8.
- If G = 6, P(W) = 12/18 and P(G) = 6/18. 12 is 2 * 6 (twice), not thrice.
- If G = 4, P(W) = 12/16 and P(G) = 4/16. 12 is 3 * 4 (thrice). This matches the condition.

The diameter of a metallic sphere is 42 cm. It is melted and drawn into a cylindrical wire of diameter 2.8 cm. The length of the wire in metre is:
A)
54 m
B)
58 m
C)
60 m
D)
63 m
Step-by-step solution:
1. **Identify the principle**: When a metallic object is melted and reshaped, its volume remains constant. Therefore, Volume of Sphere = Volume of Cylinder.
2. **Calculate Volume of the Sphere**:
- Diameter of sphere ($D$) = 42 cm
- Radius of sphere ($R$) = $D/2 = 21$ cm
- Formula for Volume of Sphere = $\frac{4}{3} \pi R^3$
- Volume = $\frac{4}{3} \times \pi \times (21)^3$
3. **Calculate Volume of the Cylindrical Wire**:
- Diameter of wire ($d$) = 2.8 cm
- Radius of wire ($r$) = $d/2 = 1.4$ cm
- Let the length of the wire be $h$ cm.
- Formula for Volume of Cylinder = $\pi r^2 h$
- Volume = $\pi \times (1.4)^2 \times h$
4. **Equate the volumes**:
$\frac{4}{3} \pi (21)^3 = \pi (1.4)^2 h$
Cancel $\pi$ from both sides:
$\frac{4}{3} \times 21 \times 21 \times 21 = 1.4 \times 1.4 \times h$
$4 \times 7 \times 21 \times 21 = 1.96 \times h$
$28 \times 441 = 1.96 \times h$
$12348 = 1.96 \times h$
5. **Solve for $h$**:
$h = \frac{12348}{1.96}$
$h = 6300$ cm
6. **Convert to metres**:
Since 100 cm = 1 m,
$h = \frac{6300}{100} = 63$ m.
Therefore, the length of the wire is 63 m, which corresponds to option (d).

You have a limited budget for a healthcare initiative. What is the crucial factor to consider when deciding which health programs to fund?
A)
Popularity of the program
B)
Political backing
C)
Program’s potential impact on public health
D)
The novelty of the program
In the context of Administrative Aptitude and Ethics, the primary goal of a public administrator is to ensure the 'greatest good for the greatest number' (Utilitarianism) and the efficient allocation of scarce public resources.
1. Why Option 'c' is correct: When dealing with a limited budget, the decision-making process must be based on 'Cost-Benefit Analysis' and 'Impact Assessment.' The crucial factor is the potential impact on public health (e.g., reduction in mortality rates, prevention of epidemics, or improvement in quality of life), as this ensures that public funds are used to achieve the maximum possible health benefit for the population.
2. Why Option 'a' is incorrect: Popularity does not always correlate with efficacy. A popular program might be superficial or fail to address the most critical health crises.
3. Why Option 'b' is incorrect: Political backing is a matter of political expediency, not administrative ethics. Funding based on political pressure rather than need is considered a failure of objective governance.
4. Why Option 'd' is incorrect: Novelty (being new or innovative) is a secondary consideration. An innovative program that has no proven impact is a riskier and less ethical choice than a proven program that saves more lives.
