Question

A cake recipe says that you need to put $3$ bowls of sugar for every $5$ bowls of flour. However, for an upcoming party, you need a bigger cake. If you use $20$ bowls of flour, how much sugar is required?

• A. $0.75$ bowls sugar
• B. $12$ bowls sugar
• C. $33.33$ bowls sugar
• D. $15$ bowls sugar

Answer 1

The correct option is B $12$ bowls sugar

For every $5$ bowls of flour, $3$ bowls of sugar are needed.

So, the ratio of bowls of sugar to bowls of flour for making the cake is $\frac{3}{5}$.

Hence, for $20$ bowls of flour, you must put the sugar in such way that ratio remains same.

Let the number of bowls of sugar be $x$.

$\frac{3}{5}=\frac{x}{20}$

$x=\frac{(20\times 3)}{5}$

$x=12$

So, for $20$ bowls of flour, $12$ bowls of sugar is required.
