Solution

GT = 2.5    ...(Given)

The point of concurrence of medians of a triangle divides each median in the ratio 2 : 1.

∴ `"PG"/"GT" = 2/1`

∴ `"PG"/2.5 = 2/1`

∴ PG = 2 × 2.5

∴ PG = 5

Now, PT = PG + GT

= 5 + 2.5

∴ PT = 7.5 units

Hence, the length of PG and PT is 5 and 7.5 units respectively.
