Answer 2

D. option is correct

Answer 3

D

45x23 = 1035
so you need to work out how the rest would add up to 1035
45x20= 900
and to get to 1035 you need 135
so 45x ? = 45x3 which = 135

and also there was already 20 x and you needed 23x so you may notice that you would need x3 to get x23...

so D=3
