25% = 4
100& = 4 x 4 = 16 kg
.
100& = 4 x 4 = 16 kg
.
you are right in saying that the 25% => 4kg.
originally, let the mass be 100%. after adding, it increased to 125%.
so now, the question is asking you to find the mass before any addition so it is just asking you to find the mass when it is 100%.
therefore 4 x 4 = 16kg.
