Paul, colin and brian are waiters. one night the restaurant earns tips totalling £71.10. they share the tips in the ratio 2: 3: 4. how much more does colin get over paul?

The amount that Colin will get more than Paul is $7.90.

From the information given, Paul's share will be:

= 2/9 × $71.10

= $15.80

The share of Colin will be:

= 3/9 × $71.10

= $23.70

The difference between Colin's share and Paul's share will be:

= $23.70 - $15.80

= $7.90

Therefore, the amount that Colin will get more than Paul is $7.90.

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

is only a line? i think so
