SSC CHSL 5 Mar 2018 Shift 3 Paper

Let price of a single bag = Rs.x and price of a bottle = Rs.y
5 bottles cost as much as 2 bags ⇒ $5\mathit{y}=2\mathit{x}$
Multiplying both sides by 3, we get : $15\mathit{y}=6\mathit{x}$ ---------(i)
According to ques,⇒ $4\mathit{x}+15\mathit{y}=2000$
Substituting value from equation(i), ⇒ $4\mathit{x}+6\mathit{x}=2000$
⇒ $\mathit{x}=\frac{2000}{10}=\mathit{R}\mathit{s}.200$
