For the period from January to March inclusive, what was the ratio of the turnover between hot drink and cold drink?

", "advice": "

This is a matter of calculating the ratio of Hot drink to Cold drink but you must take care to only use the information for January to March only.

\n

(9000+8000+8400)/(3000+4800+4900) = 2 = 2/1

\n

Hence ratio 2:1, answer A

Which if the following best represents the ratio of profits between USA in 2016 with UK in 2017?

\n

", "advice": "

Note that each year has a different total profit. In addition, you are going to have to calculate the value of the profit for different countries in different years. This is done as follows:

\n

\n

USA (2016) = 0.16 x £209 m = £33.44 m

\n

UK ( 2017) = 0.23 x 195 = £44.85 m

\n

Ratio = 33.44/44.86 =0.7455. This is approximately 0.75 which is equal to 3/4 = 3:4
