Solution

The correct option is A 7
Observe row 3 of multiplication:
3 X C gives 1 in units place. So C = 7
( 3 X B ) + 2 gives 6 in units place
so 3 X B could be 24 . So B = 8
Observe row 2 of multiplication
5 X 7 (C) = 35
5 X 8 (B) + 3 = 43
9 X 5 +4 = 49 . So A = 9
Observe row 1 of multiplication
D X 7 gives 8 in its unit place so D is 4.
So option A.
