What are you looking for? Letâ€™s dig in quickly

Explanation

• On sport day 30 children were made to stand in a column = 16 columns.
• If 24 children were made to stand in a column = ? column (columns are needed to calculate).

We need to establish a relation between no. of children and no. of columns.

• Less children in a column means more column.
• And more children in a column means less column.

So can easily find out the relation is inverse and equation becomes;

30/24 = y/16

Through this equation; we can easily find out the value of y (required number of columns = 20 which is our required answer).

To Find

No. of columns if 24 children were made to stand in a column = ?

Solution

Children                                  Column

30                                            16

24                                            y

More children in a column means less columns.

And less children in a column means more columns. So there is inverse relation;

30/24 = y/16

30 x 16 = 24 x y

480 = 24y

480/24 = y

20 = y

Required number of columns = 20 answer

Conclusion

On sport day, 30 children were made to stand in a column, then 16 columns could be formed. If 24 children were made to stand in a column, then 20 columns could be formed.
