Answer 1

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.
