Which company's shares contribute the greatest value to the portfolio on 31st January?

", "advice": "

This requires you to be able to use your calculator efficiently and note down the values as you are comparing for each company type.

The calculations in GBP (£) but you can do these in pence if you wish:

Alternatively, to make calculations quicker you can compare the results of the following and find the greatest value (here all the values in the first column have been divided by 100):

This chart shows the annual profit made by two teams within a company over 5 years.

\n

", "advice": "

Here, you need to calculate the contribution to profits for each year for Team 2 and find the smallest contribution in terms of percentages.

\n

In order for Team 2 to make the smallest percentage contribution you can eliminate some years where the Team 2 bar is smallest than the Team 1 bar. This would mean you only look at Year 2, Year 3 and Year 4 since it is clear that the Team 2’s contribution is smaller than Team 1.

\n

These are the calculations that have to be made using (Team 2 value/total) x 100%. Using your mental arithmetic would be helpful here as the values are in multiples of 5

\n\n

ANSWER is year 3 has lowest contribution in terms of percentages.
