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.
