A man took a cab from his home to reach office. On the way back, he took a cab again. When he had reached his office, he paid 1/6th of what he had in his wallet and when he returned home, he paid 1/5th of what he had left in his wallet. In the first trip the fare was $60. How much money did he initially have and how much is left with him now?

$360 - money a man initially have
$240 - money left

$360 - money a man initially have
$240 - money left

$360 & $240 respectively.
Let the initial amount in his wallet be 'X'. In the first journey, he paid 1/6th of X which we know is $60. So the equation is
1⁄6 x X = 60
X⁄6 = 60
X = 360

Hence, the initial amount is $360.
Now that he has paid $60 for the first trip, he is left with $(360-60) = $300.
In the return trip he pays 1/5th of what he had left which was $300. So if he pays 'Y' for the return trip, then the equation is
Y = 1⁄5 x 300
Y = 60
Hence after the return trip, he is left with $(300-60) = $240.

2 points for you!

They are all a single letter followed by a palindrome, so if you move the first letter to the end, you get the word  backwards

In an 800 m marathon, Steve managed to overtake his friend, Roderick, in the last 7 seconds of the race, who would have otherwise finished second.
1.  What place did Steve achieve after overtaking his friend?
2.  What place would Steve have achieved had he managed to overtake the last runner?

1. Steve stood second by overtaking the second runner and not first which is a common mistake made by most of us.
2. How can one overtake the last runner?

2. technically if you overtook the last runner that means you are first and have gone too fast that you have been able to overtake the last runner (assuming the track is oval)

Mrs. Benette was a school teacher who noticed that she took the same time to go to school in the morning as she took on her return journey from school back home, in the evening. One day she happened to discover something.

When she left home, the hour hand and the minute hand were cast exactly opposite each other and on reaching school she found them to be together.

Similarly, when she quit school in the evening, the hour hand and the minute hand were together and the moment she arrived home, they were exactly opposite each other.
How much time did Mrs. Benette spend traveling? Give the minimal possible answer.

30min is the closest (give or take a few minutes)

its the only possible way that you see a clock at opposite each other and then together after some time

Fun fact is the minute and the hour hands are together 11 times and opposite of each other 11 times as well in 12 hours.

We know that every 12:00, the hands are together, then at 6:00, the hands are opposite each other. However after 6:00, the hands are opposite of each other not at 06:30:00 but at 6:32, and after 12:00, the hands are exactly opposite at 12:32, not 12:30.

She must have left home 6:00 in the morning and reached the school around 6:32, and left the school 6:00 in the evening and reached home by 6:32. (Supposedly 8 hours lang ang work, pero dahil teacher siya, marami talaga ginagawa sa school pa after classes. I should know. Hahaha)

So that means it takes 32 minutes and some seconds for her to reach her destination. Multiply that by two for total travel time which equals to roughly 1 hour and 5 minutes.

I agree with the answer above , about the 32 minutes thing . from a reference i had read, yet my answer would be 32*2 = 64 minutes , which is equal to an hour and 4 minutes . :)

the minimal wold be around an hour to an hour and 4 minutes and thats my final answer Shiing!~

One evening you are sitting in a room with no windows and the door shut. Suddenly you hear two cars drive up outside. From the noise of the engines you can make out that one car's engine is well tuned, whereas the other car's engine is in urgent need of repair. The engines are switched off and you are asked to go out and identify the car with the good engine. You are allowed to start only one engine to hear the noise. However, when you get outside, you find 3 cars. You are told that one of them was already there for a long time. How can you be sure to find the car with the good engine?

Simple, I touch the hood of the cars and identify the two out of the three that are warm. Since the cars have just arrived, both of them should be still warm.

Then I choose either one of the warm cars and start the engine. If the car I switched on sounds horrible, like spurting and vibrating unceremoniously, then the car with the good engine is definitely the other warm car. If not, then I'm sitting in the car with the good engine.

In a car manufacturing plant at Detroit, there is a shortage of steering wheels, horns and headlights during manufacturing of a particular batch of cars. It is found that:
All cars do not have either steering wheel or horn or headlight
Exactly 19% of cars do not have just one of these
Atleast 67% of cars do not have steering wheels
Atleast 83% of cars do not have horns
Atleast 73% of cars do not have headlights
What percentage of cars do not have steering wheel, horn and headlight?

assuming 100 cars, mga around 42%

since 19% lang ang may isang kulang and we are looking for the number na tatlo ang kulang na parts sa 100 cars, so only have to figure it out from 81%
sa 100 cars, you will have 100 of each item, total of 300

67 ang kulang sa steering
83 ang kulang sa horn
73 kulang sa head light

lahat ng kulang is 223

pero since 19 ang sure ka na kulang talaga, 223 - 19 = 204 nalang ang unaccounted
assuming lahat ng 81 is kulang ng 3 over ka since that would mean 243 lahat so hindi lahat ng natirang 81 3 ang kulang
so what if tig 2 lang ang kulang nung 81, so 162 may kulang pa na 42, so ibig sabihin yung 42 na yun tig 3 ang kulang

so 42 out of 100 = 42%

42% cars do not have steering wheel, horn and headlight.
Since figures are supplied in percentages, let us assume that there are 100 cars. Hence, there should be total 300 items i.e. 100 steering wheels, 100 horns and 100 headlights.
From the given data, we know that there is shortage of at least (67+83+73) 223 items in every 100 cars.
Also, exactly 19 cars do not have just one item. It means that remaining 81 cars should account for the shortage of remaining (223-19) 204 items.
If those remaining 81 cars do not have 2 items each, there would be a shortage of 162 items. But total of 204 items are short.
Hence, at least (204-162) 42 cars do not have all 3 items - steering wheel, horn and headlight.

Six people A, B, C, D, E, and F are given choice to choose for the following posts:

President

Vice president

Secretary

Treasurer

But they have some conditions:

F wants to be President if E is Vice president.
B does not want to be either President or Vice president.
E does not work if both A and B work.
D does not work if any of A and B works.
C works only if F works along with B.
Can you specify who gets which post?
