Solubility is reduced due to common ion effect.
When AgCl is dissolved it releases Ag+ and Cl- ions
(a) NaCl -NaCl will release Na+ and Cl- .

So due to increase in concentration of common ion ( Cl-) rection will move in backward direction and solubility decreased.
(b)

There is no common ion effect so solubility of AgCl will not decreased.
(c)
![A g subscript 2 C r O subscript 4 left right double arrow 2 A g to the power of plus plus thin space C r O subscript 4 to the power of minus](https://images.topperlearning.com/topper/tinymce/cache/843a9f7493ac52dcb02f3dfa72ddd7f4.png)
Here common ion effect is due to Ag+ ions. So solubility is decreased.
This decrease in solubility will be more as compared to NaCl because in NaCl, 1 Cl- ion is available for one AgCl molecule, In Ag2CrO4, 2 Ag+ ions are available for one AgCl molecule. So common ion effect in Ag2CrO4 is more effective.
Order of solubility -
