The senior classes at High School A and High School B planned separate trips to New York City. The senior class at High School A rented and filled 12 vans and 3 buses with 324 students. High School B rented and filled 6 vans and 8 buses with 474 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
