প্রশ্নে বলা হচ্ছে যে, 60 লিটারের একটি মিশ্রণে দুধ ও পানি 2 : 1 অনুপাতে আছে। কতটুকু পানি মেশালে দুধ ও পানির অনুপাত 1 : 2 হবে?

Sum of the given ratio = 2 + 1 = 3

∴ Quantity of milk $= (60 o f \frac{2}{3}) = 40 l i t e r s$

Hence, quantity of water will be = 60-40 = 20 liters

Assume, x liters water needs to be added.

∴ According to question, $\frac{40}{x + 20} = \frac{1}{2}$

$\Rightarrow x + 20 = 80 \Rightarrow x = 80 - 20 = 60 ∴ x = 60 S o, 60 l i t e r s w a t e r n e e d s t o b e a d d e d .$
