Please explain, how did you come up with these answers.

Since there is insufficient information in each individual question to solve them individually, the questions must be connected, implying that their solutions are also connected.

So, I took each known value and created a set of factors and LCMs:

10=2×5, 24=2×2×2×3, LCM=120

4=2×2, 20=2×2×5, LCM=20

15=3×5, 25=5×5, LCM=75

The set is: 2, 2, 2, 3, 5, 5, LCM=600.

Then, I divided the LCM for each question into the LCM for the set:

5,

30,

8,

to give me the missing values.

The questioner only asked for the answers, not the method.
