$\color {red}\huge\bold\star\underline\mathcal{Question:-}$

We have to find CP of A .

$\bold{\boxed{\huge{\boxed{\orange{\small{\boxed{\huge{\red{\bold{\:Answer}}}}}}}}}}$

we know that ,

$cp = \frac{sp \times 100}{(100 + p)}$

so, CP for b was ==

$cp \: for \: b \ \: = \frac{3213 \times 100}{102} = 3150$

Now, Again using same concept :---

$cp \: for \: a \: was \: = \frac{3150 \times 100}{105} = 3000$

So, A pay
