Here are some questions regarding my maths holiday homework. I want answers from a person who is good at maths?
1- A train covers a certain distance at a uniform rate. On increasing its speed by 5 km/hr it saves 20 minutes and on decreasing its speed by 20km/hr it loses 2 hrs. Find the distance covered by the train.
2- A man sold a chair and a table together for Rs 1520 thereby making a profit of 25% on the chair and 10% on the table. By selling them together for Rs 1535, he would have made a profit of 10% on the chair and 25% on the table. Find the cost price of each.
3- Students of a class are made to stand in rows. If 4 students are extra in a row, there would be 4 rows less. On the other hand, if 2 students are less in a row, there would be 4 rows more. Find the number of students in the class.
4- A fruit seller has certain number of oranges. He divides them into 2 lots- A and B. He sells the lot A at 3 oranges for Rs 2 and the lot B at 1 orange for Re 1. He thus gets Rs 400. If he had sold the first lot at 1 orange for Re 1 and the second lot B at 5 oranges for Rs 4, he would have got Rs 460. Find the total number of oranges.
5- It can take 12 hrs to fill a swimming pool using 2 pipes. If the pipe of larger diameter is used for 4 hrs and the pipe of smaller diameter 9 hrs, only half the pool can be filled. How long would it take each pipe to fill the pool separately.

My mom and dad say do a course in French language cause then I will get a good chance to go abroad, though i am good at french, i want to do fashion designing or mass media and communication or anything different like this. But my mom says no to fashion designing but my dad is very supportive. I am planning to do commerce in 11th and 12th with maths, but nowadays getting admission in top notch colleges like SRCC or LSR is very difficult due to their cut off percentage (don't know if the system and cut off percentage changes in 2-3 years). An besides all this i want a good job out of india, don't want to do anything here in india. And if i get admission in a good college of commerce, my father is planning to get my MBA done from singapore or somewhere else........though i am fully sure to study commerce in 11th and 12th but don't know what to do after that except fashion designing or mass media or anything else like that is easy to get.........but pursuing a career in commerce field.......just don't know about it!! so plzz help.........i just want a good career abroad!!5 AnswersStudying Abroad9 years ago
