  Let $f$ and $g$ be two Hecke-Maass or holomorphic primitive cusp forms for
$SL(2,\mathbb{Z})$ and $\chi$ be a primitive Dirichlet character of modulus
$p$, a prime. A subconvex bound for the central values of the Rankin-Selberg
L-functions is $L(s, f \otimes g \otimes \chi)$ is give by $$L(\frac{1}{2}, f
\otimes g \otimes \chi) \ll_{f,g,\epsilon}p^{\frac{22}{23}+\epsilon} ,$$ for
any $\epsilon > 0$, where the implied constant depends only on the forms $f,g$
and $\epsilon$.
