There are 498 coins in a bottle 1/3 of the coins are in pounds 124 of the coins are 50p and the rest are 20p work out the total value of 498 coins

Step-by-step explanation:

No. of coins in pounds → 1/3 x 498 = 166

No. of coins in 50p → 124

No. of coins in 20p → 498 - 166 - 124 = 208

Total Value: 166pounds + 124 (50p) + 208 (20p)

unfortunately, I do not know the exact currencies of pounds and "p" so I'm sorry I'm afraid but I can't calculate the total value

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
