A bag contains 135 marbles some white and some transparent. The ratio of white marbles to transparent ones is 3 : 6. How many wh

Setler [38]

Answer:

Number of white marbles in the bag = 45

Step-by-step explanation:

Total number of marbles in the bag = 135

Ratio of white marble to transparent ones = 3 : 6

Let number of white marbles be $=3k$

Then number of transparent marble will be $=6k$

Total number of marbles will be $=3k+6k=9k$

So we have.

$9k=135$

Dividing both sides by 9.

$\frac{9k}{9}=\frac{135}{9}$

∴ $k=15$

∴ Number of white marbles in the bag = $3k=3\times15 = 45$
