Given:
An apple farmer arranges apples in a 5 layered box, the first layer has 8 columns and 12 rows of 1 apple each. The subsequent layer will have 1 less of each column and row.
To find:
How many apples will be in the 4th layer?
Solution:
From given, we have,
An apple farmer arranges apples in a 5 layered box.
The first layer has 8 columns and 12 rows of 1 apple each.
The subsequent layer will have 1 less of each column and row.
The second layer has 7 columns and 11 rows of 1 apple each.
The third layer has 6 columns and 10 rows of 1 apple each.
The fourth layer has 5 columns and 9 rows of 1 apple each. = 5 × 9 = 45 apples as each has 1 apple.
Therefore, 45 apples will be in the 4th layer.
