Question

To make a cup of tea, the ratio of water to milk is $3:1$. To make $4$ cups of tea the ratio of water to milk is :

• A. $4:3$
• B. $12:1$
• C. $12:4$
• D. $4:12$

Answer 1

The correct option is C $12:4$

A $cup$ of tea has Water to Milk Ratio

$W:M=3:1$

where $W$ and $M$ are $Water$ and $Milk$

Now, $4$ cups will have $4$ times the $Water$ and $milk$ of a single $cup$.

So, the ratio will be

$=\frac{3\times 4}{1\times 4}$

$=\frac{12}{4}$ or $12:4$.
