Answer 1

$$\begin{gathered} \mathrm{Let}\mathrm{the}\mathrm{present}\mathrm{age}\mathrm{of}\mathrm{Anil}=\mathrm{x}\mathrm{yrs} \\ \mathrm{Now},\mathrm{age}\mathrm{of}\mathrm{Anil}4\mathrm{yrs}\mathrm{ago}=\left(\mathrm{x}-4\right)\mathrm{yrs} \\ \mathrm{Now},\mathrm{according}\mathrm{to}\mathrm{question}: \\ \mathrm{x}+3\left(\mathrm{x}-4\right)=3\mathrm{x}+2 \\ \Rightarrow \mathrm{x}+3\mathrm{x}-12=3\mathrm{x}+2 \\ \Rightarrow \mathrm{x}-12=2 \\ \Rightarrow \mathrm{x}=2+12 \\ \Rightarrow \mathrm{x}=14 \\ \mathrm{So},\mathrm{present}\mathrm{age}\mathrm{of}\mathrm{Anil}=14\mathrm{yrs} \end{gathered}$$
