Question

Divide $20$marbles between Raju and Tanu in ratio of $2:3?$

Answer 1

Step 1:By unitary method:

Total number of marbles$=20$

Marbles are divided at ratio $=2:3$

Let "$x$" be common in given ratio.

So,

$$\begin{gathered} 2x+3x=20 \\ 5x=20 \\ x=\frac{20}{5}=4 \end{gathered}$$

The value of $x$ is $4$

Step 2: Number of marbles with Raju$=4\times 2=8$

Number of marbles with Tanu $=4\times 3=12$

Hence, Raju has $8$marbles and Tanu has $12$marbles with them.
