B.

As,
5 * 3 = 5 x 3 + (5 - 3)2 = 15 + 4 = 19
8 * 5 = 8 x 5 + (8 - 5)2 = 40 + 9 = 49
Similarly, 6 * 4 = 6 x 4 + (6 - 4)2 = 24 + 4 = 28
If '+' stands for 'multiplication', '-' stands for 'addition', 'X' stands for 'division' and '÷' stands of 'subtraction', then which one of the following equation is correct?
9 + 8 - 4 x 2 ÷ 18 = 56
9 x 8 + 4 ÷ 2 - 18 = 26
9 x 8 ÷ 4 + 2 - 18 = 200
9 - 8 x 4 + 2 ÷ 18 = 203
