Vector Algebra: JEE Main 2023 Mathematics question

Let $\overrightarrow a = 4\widehat i + 3\widehat j$ and $\overrightarrow b = 3\widehat i - 4\widehat j + 5\widehat k$. If $\overrightarrow c$ is a vector such that $\overrightarrow c .\left( {\overrightarrow a \times \overrightarrow b } \right) + 25 = 0,\overrightarrow c \,.(\widehat i + \widehat j + \widehat k) = 4$, and projection of $\overrightarrow c$ on $\overrightarrow a$ is 1, then the projection of $\overrightarrow c$ on $\overrightarrow b$ equals :
