The final solution looks like this:

This is a bar graph question – a very common type in the interactive versions of the SHL Numerical Reasoning and General Ability tests.
We recommend solving these questions with the help of a table:

- The bold cells are what we actually need to find.
- Bold type numbers represent data given in the question. Regular type numbers are derived from that data.
- The Roman numerals in parentheses (I) represent the equation used to derive that number (see below).
Formulating equations and calculations:
- (Stocks Ben) + 50 + (Stocks Ben) = 250 → (Stocks Ben) = 100
- 1050 – 700 = 350
- 1050 – 500 – 250 = 300
- 100/250 = 40%
- 350 x 30% = 105 (Adam manages 30% of total stocks)
- 350 – 100 – 105 = 145
- 145/500 = 29%
This is where we stop. No need to calculate further.
What’s good about this solving method is that it shows you EXACTLY the data you need to find, as well as how simple it is to calculate with the horizontal-and-vertical structure of the table.
