If the cost of $4\frac{2}{4}$ litres of juice is $₹100\frac{1}{4}$, then what is its cost per litre?

• A. $₹22\frac{5}{18}$
• B. $₹22\frac{3}{18}$
• C. $₹18\frac{4}{18}$
• D. $₹23\frac{5}{18}$

Answer 1

The correct option is A $₹22\frac{5}{18}$

$Costof4\frac{2}{4}litresofjuice=₹100\frac{1}{4}$

$\Rightarrow Costof\frac{16+2}{4}litresofjuice=₹\frac{(400+1)}{4}$

$\Rightarrow Costof\frac{18}{4}litresofjuice=₹\frac{401}{4}$

$\Rightarrow Costof1litreofjuice=₹(\frac{401}{4}÷\frac{18}{4})=₹(\frac{401}{4}\times \frac{4}{18})=₹\frac{401}{18}=₹22\frac{5}{18}$
