### The egg vendor calls on his first customer & sells half his eggs & half an egg.  To the 2nd customer he sells half of what he sells half of what he had left & half an egg. & to the 3rd customer he sells half what he had then left & half an egg. By the way he did not break any eggs. In the end three eggs were remaining .  How many total eggs he was having ?

• A.

56

• B.

38

• C.

34

• D.

24

B. 38
Explanation
The egg vendor starts with a certain number of eggs. He sells half of his eggs (which is an even number) and half an egg. This means that the number of eggs he had initially must be an odd number.

To the second customer, he sells half of what he had left and half an egg. Since he had an odd number of eggs left after the first sale, half of that would be an odd number as well.

To the third customer, he sells half of what he had then left and half an egg. Again, since he had an odd number of eggs left after the second sale, half of that would be an odd number as well.

In the end, three eggs were remaining. This means that the number of eggs he had initially must be three more than a multiple of four. The only answer choice that satisfies this condition is 38, which is three more than a multiple of four.

• C.

(24/12)*21

• D.

(23/11)*20

• E.

(22/11)*19

B. (24/11)*19
Explanation
The runner reaches the 12th flag in 24 seconds. Since the flag poles are equidistant from each other, the runner covers 12 flag poles in 24 seconds. Therefore, the runner takes 2 seconds to cover each flag pole. To calculate the time it will take him to complete the 20th flag, we multiply the time taken for each flag pole by the total number of flag poles. So, (2 seconds/flag pole) * 20 flag poles = 40 seconds. However, none of the answer choices match this calculation, so the correct answer is not available.

55 Sec

• C.

1 Hr

• D.

2 hrs

• E.

33 sec

A. 66 sec
Explanation
The clock rings 6 times in 30 seconds, so the time between each ring is 30/6 = 5 seconds. At 12 o'clock, the clock will ring 12 times, so the total time it takes is 5 * 12 = 60 seconds. However, this does not include the time between the first and last ring, which was 30 seconds. Therefore, the total time it takes at 12 o'clock is 60 + 30 = 90 seconds. However, none of the given options match this answer, so the correct answer is not available.

• B.

B. Tends to oppose change in current

• C.

C. Tends to oppose change in voltage

• D.

D. Opposes all frequencies equally

B. B. Tends to oppose change in current
Explanation
Inductance is a property of an electrical circuit that tends to oppose any change in current. When the current in a circuit is increasing, an inductor generates a back EMF (electromotive force) that opposes the increase in current. Similarly, when the current is decreasing, the inductor generates a forward EMF that opposes the decrease in current. This opposition to changes in current is a characteristic of inductance.
