Platinum is costlier although gold is a symbol of wealth and money and many people believe that gold is the most costliest metal.
Platinum is costlier than Diamond . Diamond has variety of qualities to assign its price, but pt is an inert metal. Platinum is a very rare and is a naturally white metal. The platinum that is usually used in jewellery is around 95% pure and is much heavier and much harder than white gold. so pt is costlier.

Yes
Gold is both rare and highly desired. The price results from the law of supply and demand.
Because there is less of it.
If by "stronger" you mean hard to bend, then platinum is less bendable than gold. For many applications gold is mixed with other materials in order to make it "harder" because pure gold is so soft. But neither gold or platinum are used for their strength, gold is mostly used for its electric properties (e.g. the connector on your mobile phone) and platinum as a catalyst in chemical reactions.
Since platinum is a harder metal to work, it needs sophisticated machinery and techniques. Platinum melts at a very high temperature of almost 1,700 to 1,800 degrees and requires considerable skill to craft into jewellery. The metal demands careful handling, precision, detailing and practice and since it is 30 times rare than gold, it is expensive. The price of the metal has appreciated over the years, and consequently platinum indeed has a resale value. But in comparison to gold, platinum's resale value is less, because of the high production costs that platinum jewellery accrues, reselling is more difficult than gold
Platinum is denser then gold.
they have gold but not platinum
Gold is not very reactive, but platinum is more nonreactive; the electronegativity of gold is 1,93 but the electronegativity of platinum is 2,23.
Yes Platinum is harder than gold and also has a higher density, so it will scratch gold. It is not advisable to wear platinum along with gold.
Yes, platinum is rarer than gold.
