1. What is the value of 7 in 1.207?
A 7 x 0.1
C 7 x 0.001
B 7 x 0.01
D 7 x 0.0001

7*0.0001 I'd the value of 7 in 1.207

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
