Abstract	We report on the extrapolated measurements related to the flavour-changing-neutral-current(FCNC) $b\rightarrow s$ and $b\rightarrow d$ transitions with the Belle II data. The branching fraction(BF) and raw asymmetry measurements of the exclusive decay $\bar{B}\rightarrow X_{q}\gamma$, time-dependent $CP$ asymmetry in the transition $b\rightarrow s\gamma$, angular analysis of $B\rightarrow K^*ll$ and $B\rightarrow X_sll$ are discussed. We also report on the searches for the decay $B\rightarrow h\nu\nu$. Most of these analyses are extrapolated with 5 and 50 ab$^{-1}$ Belle II data.
