Question

There are bundles of different colored sticks. Using the given table, calculate how many more pink sticks are there as compared to the combined number of white and blue sticks.

$\begin{array}{ccc}\text{Color of sticks}& \text{Number of sticks in each bundle}& \text{Number of bundles}\\ \text{White}& 20& 3\\ \text{Pink}& 10& 15\\ \text{Blue}& 30& 2\end{array}$

Answer 1

Let us find the total number of sticks for each color one by one.

Let us represent $10$ colored sticks by $10$ blocks.
$10$ blocks $=1$ rod
$10$ colored sticks $=1$ rod

For white sticks,

Number of bundles $=3$
Number of sticks in each bundle $=20$
Total number of white sticks $=3\times 20$
$10$ sticks are represented by $1$ rod.
$20$ sticks will be represented by $2$ rods.


Total number of white sticks $=60$

For pink sticks,

Number of bundles $=15$
Number of sticks in each bundle $=10$
Total number of white sticks $=15\times 10$
$10$ sticks are represented by $1$ rod.

Total number of pink sticks $=150$

For blue sticks,

Number of bundles $=2$
Number of sticks in each bundle $=30$
Total number of white sticks $=2\times 30$
$10$ sticks are represented by $1$ rod.
$30$ sticks will be represented by $3$ rods.

Total number of blue sticks $=60$

Total number of white sticks $+$ Total number of blue sticks
$=60+60$

$=120$ sticks
Difference $=$ Number of pink sticks $-$ Total number of white and blue sticks
$=150-120$
$=30$ sticks
There are $30$ more pink sticks than the combined number of white and blue sticks.

Hence, the correct option is B.
