A dimension is called a
The dimension of the first smaller version is (100%-20%)a = 80%a
The dimension of the second smaller version is (100%-15%) of first version = 80%.a x 85% = 68%
=> Choice D
The dimension of the first smaller version is (100%-20%)a = 80%a
The dimension of the second smaller version is (100%-15%) of first version = 80%.a x 85% = 68%
=> Choice D

Let the original dimension be length 100 & width 80
20% reduction : 80 * 64
15 % reduction: 68 * 54
change is option D 68%
20% reduction : 80 * 64
15 % reduction: 68 * 54
change is option D 68%
