Question

A box contains marbles of different colours as represented in the image given below: What fraction of the marbles are equal?

• A. $\frac{\text{Number of green marbles}}{\text{Total number of marbles}}$ and $\frac{\text{Number of blue marbles}}{\text{Total number of marbles}}$
• B. $\frac{\text{Number of green marbles}}{\text{Total number of marbles}}$ and $\frac{\text{Number of red marbles}}{\text{Total number of marbles}}$
• C. $\frac{\text{Number of green marbles}}{\text{Total number of marbles}}$ and $\frac{\text{Number of white marbles}}{\text{Total number of marbles}}$
• D. None of these

Answer 1

The correct option is A

$\frac{\text{Number of green marbles}}{\text{Total number of marbles}}$ and $\frac{\text{Number of blue marbles}}{\text{Total number of marbles}}$

Total number of marbles in the box = 21 ( 5 blue, 5 green, 1 white, 10 red)

$A:\frac{\text{Number of green marbles}}{\text{Total number of marbles}}$ and $\frac{\text{Number of blue marbles}}{\text{Total number of marbles}}=\frac{5}{21}$ and $\frac{5}{21}$

$B:\frac{\text{Number of green marbles}}{\text{Total number of marbles}}$ and $\frac{\text{Number of red marbles}}{\text{Total number of marbles}}=\frac{5}{21}$ and $\frac{10}{21}$

$C:\frac{\text{Number of green marbles}}{\text{Total number of marbles}}$ and $\frac{\text{Number of white marbles}}{\text{Total number of marbles}}=\frac{5}{21}$ and $\frac{1}{21}$
