Find the number of primes $p$ between $100$ and $200$ for which $x^{11}+y^{16}\equiv 2013\pmod p$ has a solution in integers $x$ and $y$.
To solve the problem, we need to determine the number of prime numbers \( p \) between 100 and 200 for which the congruence \( x^{11} + y^{16} \equiv 2013 \pmod{p} \) has a solution in integers \( x \) and \( y \).

1. **Analyzing the Congruence:**
   We start by analyzing the given congruence \( x^{11} + y^{16} \equiv 2013 \pmod{p} \). For this congruence to have a solution, we need to ensure that the values \( x^{11} \) and \( y^{16} \) can cover all residues modulo \( p \).

2. **Case 1: \( 11 \nmid p-1 \):**
   If \( 11 \nmid p-1 \), then \( x^{11} \pmod{p} \) can take on all possible residues modulo \( p \). This is because the order of any element modulo \( p \) must divide \( p-1 \), and if \( 11 \nmid p-1 \), then \( x^{11} \) will cycle through all residues modulo \( p \). Therefore, we can always find an \( x \) such that \( x^{11} \equiv 2013 - y^{16} \pmod{p} \) for some \( y \).

3. **Case 2: \( 11 \mid p-1 \):**
   If \( 11 \mid p-1 \), then \( x^{11} \) will not cover all residues modulo \( p \). However, we can still find a solution by setting \( y = 0 \). This reduces the congruence to \( x^{11} \equiv 2013 \pmod{p} \). Since \( 11 \mid p-1 \), \( x^{11} \) will cover all residues modulo \( p \), and thus there exists an \( x \) such that \( x^{11} \equiv 2013 \pmod{p} \).

4. **Counting the Primes:**
   Since both cases ensure that the congruence \( x^{11} + y^{16} \equiv 2013 \pmod{p} \) has a solution for any prime \( p \) between 100 and 200, we need to count the number of primes in this range.

   The primes between 100 and 200 are:
   \[
   101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199
   \]

   Counting these primes, we find there are 21 primes.

Conclusion:
The number of primes \( p \) between 100 and 200 for which \( x^{11} + y^{16} \equiv 2013 \pmod{p} \) has a solution in integers \( x \) and \( y \) is \( \boxed{21} \).
