How effective is the 105mm against Indian tanks like Arjun and T-90? I’d assume those would it’s only potential tank vs tank fight enemies.

From penetration and armour values, the 105mm gun on the ZTQ 15 firing APFSDS should be sufficient to penetrate or mission kill t-90 in nearly all aspects perhaps except for the turret front.
The Arjun is a similar story. With thicker armour on the hull but poor armour on the turret caused by major weak spots and uneven coverage. Whilst the turret may be resistant in places, the armour as a whole would be penetrable by the ZTQ 15 and of course still susceptible to mission kill like any tank.
The differentiating factor or the ZTQ 15 is that as a light tank, it is designed to operate in mountainous terrain as well as high altitudes. Places where MBTs like the T90, Arjun and Type 99A would not be able to get to both in terms of mobility and engines be unable to operate in thin atmospheres.
Additionally in its role, the ZTQ 15 is designed to achieve greater gun elevation and depression to be suitable for a mountain role. Something that may beat out MBTs that get to mountainous terrain.
I have read the the 120mm main gun on the Arjun firing an APFSDS can only penetrate around 300mm of RHA at 2000m. This is compared to 500mm RHA at 2km from the 105mm found on the ZTQ. The penetration value from the Arjun is such that many parts of the ZTQ 15 could quite easily withstand. But again still susceptible to mission kill.
The T90 however would have a more lethal punch despite similar armour compared the the Arjun.
In such terrain it is likely that the only vehicles encountered will be APCs, IFVs and other light tanks. So a 105mm is more than sufficient.
