A train running at 25 km/hr takes 18 seconds to pass a platform. Next, it takes 12 seconds to pass a man standing still. Find the length of the train and that of the platform.  Choose the correct choice from the following choices: A) 83.3m41.7m B) 100m50m C) 50.8m45.7m D) 100/3 m200/3 E) none of these

Solution: A train running at 25 km/hr takes 18 seconds to pass a platform. Next, it takes 12 seconds to pass a man walking at 5 km/hr in the same direction. Find the length of the train and that of the platform.   Distance = Speed*time   It's probably best to convert to meters so we can find the length of the platform.   Distance = 25000 meters/h * 18 seconds*(1/60*60)   Distance =(25000*18 / [3600] ) = 125m   I'm not sure how we take the length of the train into account (if we do at all) to solve this problem. For example, If we were measuring by the time the very front of the train passed one end of the platform to the time the very front of the train passed the other end, the result would be different than if we counted when the very front of the train passed one end of the platform to the time the back side of the train passed the end.   As for the problem involving the man, the man is standing still while the train is moving forward at a speed of 25km/h. Therefore, the train is moving past the man at a total speed of 25km/h.   distance (25000*18 /  3600  )= 
(25000*18 /  3600  ) = 125
125m   I'm not sure how we take the length of the train into account (if we do at all) to solve this problem. For example, If we were measuring by the time the very front of the train passed one end of the platform to the time the very front of the train passed the other end, the result would be different than if we counted when the very front of the train passed one end of the platform to the time the back side of the train passed the end.   As for the problem involving the man, the man is standing still while the train is moving forward at a speed of 25km/h. Therefore, the train is moving past the man at a total speed of 25km/h.   distance= speed * time   distance = 25km/h * 12 seconds   distance (length of train) = 83.3 m   We know the length of the train is roughly 83.3m and the distance covered passing the platform was 125m. However, The platform isn't 125m long - it is 125m minus the length of the train long (or so I think) which is 125-83.3 or roughly 41.7m. Both of these answers are in A so I think that is the right answer. I am still having a bit of trouble conceptualizing why we have to subtract out the length of the train, however.   83.3m41.7mNSWER: 83.3m41.7m) 83.3m41.7m

A) 8 B) 10 C) 12 D) 14 E) 16

Solution: x = the number of red balls   y = the number of blue balls   z = the number of white balls   From the first sentence we have   Equation #1: x + y + z = 100   ...the box has 5 more blue balls than white balls...   Equation #2: y = 5 + z   ...thrice as many red balls as blue balls...   Equation #3: x = 3y   Solve equation #2 for z: z = y - 5   Now, we can replace both x and z with y in Equation #1   3y + y + (y - 5) = 100   5y - 5 = 100   5y = 105   y = 21   There are 21 blue balls. This is 5 more than the number of white balls, so z = 16. That's the answer. Just as a check, x = 63, and   63 + 21 + 16=

Answer: A
If n = 6p, where p is a prime number greater than 2, how many different positiveevendivisors does n have, including n ? Choose the correct choice from the following answers.
A) Two
B) Three
C) Four
D) Six
E) Eight

Solution: This is an interesting question because we are immediately given the option to insert any prime number we wish for p. Since this is a problem-solving question, and there can only be one correct answer, we can select any value for p, as long as it is a prime number greater than 2. We always want to work with small numbers, so we should select 3 for p. Thus, we have:   n = 4 x 3   n = 12   Next we have to determine all the factors, or divisors, of P. Remember the term factor is synonymous with the term divisor.   1, 12, 6, 2, 4, 3   From this we see that we have 4 even divisors: 12, 6, 2, and 4.   If you are concerned that trying just one value of p might not substantiate the answer, try another value for p. Let’s say p = 5, so   n = 4 x 5   n = 20   The divisors of 20 are: 1, 20, 2, 10, 4, 5. Of these, 4 are even: 20, 2, 10 and 4. As we can see, again we have 4 even divisors.   No matter what the value of p, as long as it is a prime number greater than 2, n will always have 4 even divisors.   The answer is Eight.
