Solution

The correct option is A $R s . 2.20$
Volume of juice purchased $= 20$ litres
Rate at which juice purchased $=$ Rs. $2.20$ per litre

$\Rightarrow$ Cost price of juice $= 20 \times 2.2 =$ Rs. $44$
In order to gain $10 %$ profit,
Selling price $= \frac{110}{100} \times 44 = 48.4$

Final volume of juice after dilution $= 22$ litres
$∴$ Rate of selling $= \frac{48.4}{22} =$ Rs. $2.20$
