Finding the relevant tab for this question may be more difficult than usual. The subject of the statement is laptops and tablets. More specifically, it refers to their relative part out of the total products sold by Arclight. Since this is still very little information to go on, our only choice is to scan through the tabs one by one.
Two tabs contain sales data ("Hard drives" and "Sales"). However, since they neither contain the total number of company products sold, nor refer to laptops and tablets specifically, these are definitely not the correct tabs. "Proceeds" is the only tab which contains information regarding laptops and tablets, and is therefore the correct tab. Nevertheless, it estimates the relative contribution of different products to the company's proceeds, not the number of products sold. Therefore, we do not have the information required to determine whether this statement is true or false.
Note: Tablets and laptops are estimated to contribute 9%+11% = 20% of the proceeds. Had we missed the fact that the statement is not about the proceeds, we might have mistakenly answered True. Always make sure you read the statement carefully and know exactly what you are looking for.
