2194 + 6873 – 1951 - ? = 3587
Correct Answer
B. 3529
Explanation
To find the missing number, we can rearrange the equation: 2194 + 6873 - 1951 - ? = 3587. Simplifying the equation, we have 7116 - ? = 3587. To solve for the missing number, we subtract 3587 from 7116, resulting in 3529. Therefore, the missing number is 3529.

A test has 20 questions. If peter gets 80% correct, how many questions did peter got wrong?
Correct Answer
A. 4
Explanation
If Peter gets 80% of the questions correct, it means he answered 80% of the questions correctly. Since there are 20 questions in total, 80% of 20 is 16. Therefore, Peter got 16 questions correct. To find out how many questions he got wrong, we subtract the number of questions he got correct from the total number of questions. So, 20 - 16 = 4. Therefore, Peter got 4 questions wrong.

The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?
Correct Answer
A. 4 years
Explanation
Since the children are born at intervals of 3 years, we can assume that the ages of the children form an arithmetic sequence. Let the age of the youngest child be x. The ages of the other children would then be x+3, x+6, x+9, and x+12. The sum of these ages is given as 50. Therefore, x + (x+3) + (x+6) + (x+9) + (x+12) = 50. Simplifying this equation gives 5x + 30 = 50. Solving for x, we find that x = 4. Hence, the age of the youngest child is 4 years.

If 20 men take 30 days to complete a job, how many days do 25 men need to complete the same job?
Correct Answer
A. 24
Explanation
If 20 men can complete the job in 30 days, it means that the total work required to complete the job is equivalent to 20 men working for 30 days. To find out how many days 25 men would take to complete the same job, we can use the concept of man-days. Since the total work required remains the same, and the number of men has increased to 25, the number of days required would decrease. By using the formula: (number of men1 * number of days1) = (number of men2 * number of days2), we can calculate that 25 men would need 24 days to complete the job.

6 11 31 121 601 ?
Correct Answer
A. 3601
Explanation
The pattern in the given sequence is that each number is obtained by multiplying the previous number by a prime number and then adding 1. Starting with 6, we multiply by 2 and add 1 to get 11. Then, we multiply 11 by 3 and add 1 to get 34. Continuing this pattern, we multiply 34 by 5 and add 1 to get 171. Finally, we multiply 171 by 7 and add 1 to get 1201. Therefore, the next number in the sequence would be obtained by multiplying 1201 by 11 and adding 1, which gives us 3601.

At 6'o clock clock ticks 6 times. The time between first and last ticks was 30sec. How much time it takes at 12'o clock.
Correct Answer
A. 66 sec
Explanation
The clock ticks 6 times in a span of 30 seconds, which means each tick takes 30/6 = 5 seconds. Since there are 12 hours on a clock, it would take 12*5 = 60 seconds for the clock to tick 12 times. However, the question asks for the time it takes at 12 o'clock, which is the same as 0 o'clock. Therefore, it would take 60/2 = 30 seconds for the clock to tick 12 times at 12 o'clock. As the question asks for the time between the first and last ticks, it would be 30 seconds * 2 = 60 seconds. However, the given options do not include this answer, so the correct answer is not available.
