Question

In Rajeev's rose garden, $\frac{3}{12}$ are white roses, $\frac{4}{12}$ are yellow roses and the rest are red roses. What fraction of the roses are red?

• A. $\frac{1}{12}$
• B. $\frac{5}{12}$
• C. $\frac{3}{12}$
• D. $\frac{4}{12}$

Answer 1

The correct option is B $\frac{5}{12}$

Let total roses $=x$

White roses $=\frac{3x}{12}$

Yellow roses $=\frac{4x}{12}$

Rest of the roses means red roses $=x-\frac{3x}{12}-\frac{4x}{12}=\frac{5x}{12}$

Fraction of red roses $=\frac{\frac{5x}{12}}{x}=\frac{5}{12}$
