There was a saying, “If you are good @ Mathematics, then you will be good at most of the subject you learn.”. I am not sure how far this is valid.

If you are interested in Mathematics, then this site is worth a try.

Last week on our way back form Tanjore, we stopped by a Motel near Vikravandi. After having food, I asked for the bill and the guy who came with the bill was not ready to give me the bill. It happens in India that we don’t leave any Tip when we pay the bill directly to the guy at the Cash desk.

He was hiding the bill and told be in English, “One Forty..”.

I asked him to give me the bill.

He gave me the bill and also pronounced it better now, “One Forteeeen…”.

It happens in India that motels are twice priced than the normal hotels. You cannot judge a difference of Rs. 26/= for the amount of food you have taken.

Beware and cross check the bills before payment.

Question  1 :- A work can be completed in 15 days by 5 person. After two days of work, we add 4 more people to the work . How long is the total duration to complete the work ?

Solve this before you go into the next one.

Question 2 :- We have food for 15 days for 2 people. After two days we received a couple of guest to our house. How long will the food last for in total?

These are simple [similar] questions which you come across in all Aptitude exams. Both are similar questions. But most people will take different ways to solve this question.

The procedure people used to solve these two questions were different. I am not sure whether the numbers really made the difference or the subject of the problem makes it. All Person-Work equations are used for solving the first one while the second one was solved directly by subtraction and division. I am not sure how people will think when the order of questioning is reversed.
