F : 343 : : L : ?
- A.
1723
- B.
2197
- C.
1728
- D.
1663
Correct Answer
B. 2197Explanation
The pattern in the given series is that each letter represents the cube of its corresponding position in the English alphabet.
F is the 6th letter, and 6^3 = 216.
L is the 12th letter, and 12^3 = 1728.
Therefore, the missing number should correspond to the letter 12 (L), so 12^3 = 2197.Rate this question:

Four of the following five are alike in a certain way based on their seating positions in the above arrangement and so form a group. Which is the one that does not belong to that group?
- A.
AG
- B.
CE
- C.
DA
- D.
AF
- E.
GB
Correct Answer
D. AFExplanation
The letters AG, CE, DA, and GB all have a common pattern in their seating positions - the first letter comes before the second letter in alphabetical order. However, the seating position of AF does not follow this pattern, as F comes before A in alphabetical order. Therefore, AF is the one that does not belong to the group.Rate this question:

It was Sunday on Jan 1, 2006. What was the day of the week Jan 1, 2010?
- A.
Sunday
- B.
Saturday
- C.
Friday
- D.
Wednesday
Correct Answer
C. FridayExplanation
To determine the day of the week on Jan 1, 2010, we need to count the number of days between Jan 1, 2006, and Jan 1, 2010. From Jan 1, 2006, to Jan 1, 2007, there are 365 days. From Jan 1, 2007, to Jan 1, 2008, there are 365 days. From Jan 1, 2008, to Jan 1, 2009, there are 366 days (leap year). From Jan 1, 2009, to Jan 1, 2010, there are 365 days. Adding all these days, we get a total of 1461 days. Since 1461 is divisible by 7, the day of the week repeats every 7 days. Therefore, Jan 1, 2010, will be the same day of the week as Jan 1, 2006, which is Friday.Rate this question:

What will be the compound interest on 5000 for 2 years at 12% per annum?
- A.
1250
- B.
1200
- C.
1272
- D.
2174
- E.
None of these
Correct Answer
C. 1272Explanation
The compound interest can be calculated using the formula A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the rate of interest, n is the number of times interest is compounded per year, and t is the number of years. In this case, P = 5000, r = 12%, n = 1 (since interest is compounded annually), and t = 2. Plugging in these values, we get A = 5000(1 + 0.12/1)^(1*2) = 5000(1 + 0.12)^2 = 5000(1.12)^2 = 5000*1.2544 = 6272. The compound interest is then A - P = 6272 - 5000 = 1272. Therefore, the correct answer is 1272.Rate this question:

If 'A' completes a piece of work in 3 days, which 'B' completes it in 5 days and 'C' takes 10 days to complete the same work. How long will they take to complete the work , if they work together?
- A.
1.5 days
- B.
4.5 days
- C.
7 days
- D.
9.8 days
Correct Answer
A. 1.5 daysExplanation
When working together, A, B, and C can complete 1/3, 1/5, and 1/10 of the work in one day, respectively. To find the time taken to complete the work together, we need to add up their individual rates of work. Adding 1/3, 1/5, and 1/10 gives us 1/1.5, which means they can complete the work in 1.5 days if they work together.Rate this question:

X and Y can do a piece of work in 20 days and 12 days respectively. X started the work alone and then after 4 days Y joined him till the completion of the work. How long did the work last?
- A.
6 days
- B.
10 days
- C.
15 days
- D.
20 days
Correct Answer
B. 10 daysExplanation
X can do 1/20 of the work in a day, while Y can do 1/12 of the work in a day. In 4 days, X completes 4/20 or 1/5 of the work. So, the remaining work is 4/5. When X and Y work together, their combined rate is 1/20 + 1/12 = 8/60 + 5/60 = 13/60 of the work per day. It will take them (4/5)/(13/60) = 48/65 days to complete the remaining work. Adding the 4 days that X worked alone, the total time taken is 48/65 + 4 = 10 days.Rate this question:

IF A's height is 10% more than the B's, then how much percent less is B's height than that of A ?
- A.
10%
- B.
10 1/9%
- C.
10 1/11%
- D.
9 1/11%
Correct Answer
D. 9 1/11%Explanation
If A's height is 10% more than B's, it means that A's height is 110% of B's height. To find out how much percent less B's height is than that of A, we can subtract B's height from A's height and express it as a percentage of A's height.
Let's assume B's height is x.
A's height would be 110% of x, which is 1.1x.
To find the percentage difference, we subtract B's height from A's height: 1.1x - x = 0.1x.
Then, we express this difference as a percentage of A's height: (0.1x/A's height) * 100.
Since we don't have the exact values of A's and B's heights, we cannot calculate the exact percentage difference. Therefore, the answer "9 1/11%" is a general representation of the percentage difference between B's height and A's height.Rate this question:

C.P of 12 pens = S.P. of 8 pens. Calculate the gain percentage.
- A.
25%
- B.
33%
- C.
37%
- D.
50%
Correct Answer
D. 50%Explanation
The gain percentage can be calculated by finding the difference between the selling price and the cost price, and then dividing that difference by the cost price and multiplying by 100. In this case, since the cost price of 12 pens is equal to the selling price of 8 pens, there is a gain of 4 pens. Therefore, the gain percentage would be 4/8 * 100 = 50%.Rate this question:

The product of two successive numbers is 4692. Which is the smaller of the two numbers?
- A.
69
- B.
62
- C.
68
- D.
67
- E.
None of these
Correct Answer
C. 68Explanation
The product of two successive numbers is 4692. To find the smaller of the two numbers, we need to find the factors of 4692. The factors of 4692 are 1, 2, 3, 4, 6, 12, 13, 26, 36, 39, 52, 78, 156, 299, 598, 897, 1196, 1794, 2392, and 3591. Since we are looking for two successive numbers, the smaller number must be one of the factors that is followed by the next factor. The factor 68 is followed by the factor 69. Therefore, the smaller of the two numbers is 68.Rate this question:

Today is Monday. After 61 days, it will be:
- A.
Wednesday
- B.
Saturday
- C.
Tuesday
- D.
Thursday
Correct Answer
B. SaturdayExplanation
Today is Monday. There are 7 days in a week, so every 7 days the day of the week repeats. After 61 days, we can divide 61 by 7 to find the remainder. 61 divided by 7 is 8 remainder 5. Therefore, after 61 days, it will be 5 days ahead of Monday, which is Saturday.Rate this question:
