Hi, I need heip with a P6 Math question.


School A and School B sent pupils, in groups of 10, for a handball match. If the 2 schools used mini vans that have a seating capacity of 14 passangers, they will need 72 vans. If they use mini vans that have a seating capacity of 19 passangers, School B will need 7 more vans than School A. If the 2 Schools do not share a van and each van is packed to the maximum capacity of 19 for School B, how many more pupils are there in School B than School A?

Thanks in advance.

In Math, there is more than one method to solve a question. How does one know which method to use?

Based on the above information, which of the following statements about the effect of soil erosion is/are true?

A) The soil particles settle on the bottom of the lake will cause the lake to become increasingly shallow.
