Answer and Explanation:
The computation of the return on investment is shown below;
We know that
Return on Investment is
= (Net Income ÷ Average Operating Assets] × 100
For Electronics
= [$29,16,000 ÷ 162,00,000] × 100
= 18%
And,
For Sporting goods
= [$20,74,000 ÷ 122,00,000] × 100
= 17%
So here the electronics department should be selected as it has high return on investment
