Given that, P→Q is a zero order reaction.
Initial concentration, [A]0=0.1M
Final concentration, [A]t=0.05M
Time taken, t=10 s
For, zero order reaction, k=

[A]0−[A]t

t

=

0.1−0.05

10

=0.005M s−1
Now, for concentration of P after 15 seconds,
0.005=

[0.05]−P

15

On solving we will get, P=0.025M
