Ratio A:B = 11:9. Weight of B = 32.4 kg. So 9 units = 32.4 kg, 1 unit = 3.6 kg. Weight of A = 11 units = 11 * 3.6 = 39.6 kg.

The ratio of A to B is 11:9, so the value of one ratio part is found by dividing the given weight of B, 32.4 kg, by 9, which equals 3.6 kg. To find the weight of A, multiply its 11 parts by the weight of one part, 3.6 kg. The result is 39.6 kg.
