Question

$24$ counters are arranged equally in $4$ rows. $12$ counters are added below the existing counters. If the counters are still arranged equally in an array, how many counters are there in each column?

• A. $6$ counters
• B. $12$ counters
• C. $4$ counters
• D. $3$ counters

Answer 1

The correct option is A $6$ counters

Total number of counters $=24$ counters
Number of rows $=4$ rows
Let the number of counters in each row be $“r”.$
Total number of counters $=$ Number of rows $\times$ Number of counters in each row
$24=4\times r$
$\Rightarrow r=24÷4=6$

Let’s see this pictorially:

$12$ more counters are added below the arrangement equally.


The number of counters in each row is still $6.$
Therefore, the number of counters in each column is $6.$

Hence, option B is correct.
