A) Ravi
B) Qadir
C) Sonam
D) Preeti
Correct Answer: B
Solution :
Given equation is \[\frac{p-3}{p+4}=\frac{p+1}{p-2}.\] On cross multiplication, we get \[(p-3)\,\,(p-2)=(p+1)\,(p+4)\] \[\Rightarrow \] \[{{p}^{2}}-5p+6={{p}^{2}}+5p+4\] \[\Rightarrow \] \[\cancel{{{p}^{2}}}-5p+6-\cancel{{{p}^{2}}}-5p-4=0\] \[\Rightarrow \] \[-10p+2=0\] \[\Rightarrow \] \[p=\frac{-2}{-10}=\frac{1}{5}\].
