Group 1 = 120
Group 4 = 1710

What is the logic ???
Simple algebra....
As per Grp2 - x+5y+7z=300
As per Grp 3 - x+7y+10z =390

3* Grp2 - 2*Grp2 will give x+y+z = 3*300-2*390 = 120. This is Group 1 answer.
Similarly,
7* Grp2 - 5* Grp3 will give
2x-z =150.... let's assume this is Grp5. We use later.
Now
6* Grp2- Grp3+ 2* Grp5 will give
9x+23y+30z = 6*300-390+2*150 = 1710.... this is Group 4.

I am working in a bus company. The company recently went under expansion and therefore there was not enough room for all the buses. As a result, twelve buses had to be stored outside.

If the company decides to expand the garage space by forty percent, enough space to accommodate the current buses will be created leaving enough space for twelve more buses if the need arises in future.

Can you calculate the number of buses that the company owns at present?
