Solution A
P958.1929859 of XCS at 19.31840697L
P1,000.0000 of Blaze at 19.41747573L
But to simplify my life I'd put in P950 of XCS and P1,000 of Blaze. It should result in a comfortable 98+ RON. Putting 1L XCS & 1L Blaze would result in 97.5 RON. Putting P960 of XCXS and P1,000 of Blaze would put the mix at a little less than 98 RON.
Solution B
Or if you want to pay P2,000 up front you tell the gas boy to put in P1,022 Blaze and P978 XCS. I'd probably do this as well. That's about 39.56L of fuel.
Our car's tank capacity is 50L. I do not think any one of us will ever run our car until fuel runs out.
Solution C
But if you are so inclined to tap up the fuel tank to 50L all you need to do is 25.07L Blaze and 24.93L XCS at the above prevailing prices. That's about P2,527.62.
Last night I put in P500 XCS and P750 Blaze.

Saw a silver 86 at ATC parking lot at 9PM and a red 86/BRZ at Petron Filinvest Alabang at 1040PM last night.

There's no need to go through all the trouble of mixing fuels just to achieve an exact 98 RON. Just go straight Blaze with 100 RON. Your car will run so much better not to mention mixing different fuel types is not advisable because of the differences in additive properties.
Manual states:
Fuel Type:
Unleaded gasoline (93 AKI [Research Octane Number 98] or higher)
If unleaded gasoline with an octane rating of 93 AKI (98 RON) is not available,
unleaded gasoline with an octane rating of 91 AKI (95 RON) may be
used with no detriment to engine durability or driveability.
Please note the words "or higher". Even 95 RON is OK if you can live with the cricket sounds.
Hope this helps
