Detailed Solution

22. Multiply each country of origin’s Average Family Length of Stay by Average Family Spend
Australia = 5.2 x 236 = 1,227.2
Spain = 2.8 x 116 = 324.8
Germany = 4.6 x 148 = 680.8
U.S.A = 6.2 x 244 = 1,512.8
Italy = 3.8 x 164 = 623.2
Thus the correct answer is (D), U.S.A

23. Step 1 – For each country of origin, calculate the amount spent per family by multiplying the Average Family Length of Stay by Average Family Spending.
This question is very similar to the previous question so you can use those workings if you still have them.
Australia = 5.2 x 236 = £1,227.20
Spain = 2.8 x 116 = £324.80
Germany = 4.6 x 148 = £680.80
U.S.A = 6.2 x 244 = £1,512.80
Italy = 3.8 x 164 = £623.20
Thus the correct answer is (C), U.S.A. (most); Spain (least)

24. Go through each answer option to determine if it is True, as follows
The ratio of German:Spanish tourists is 1:2
660:1300 = 33:65
So False
There are less Spanish tourists than German and Italian tourists combined:
1,300 (Spanish tourists) > 660 + 550 (German and Italian tourists combined)
So False
German families have the longest average length of stay:
Longest average length of stay = 6.2 (U.S.A)
So False
Total German tourist spending is more than 92% of Total Spanish tourist spending:
92% of Spanish tourist spending = 92% x 410 = 377.2 (< 380)
So True
There are over 4 times as many Australian tourists as Italian tourists:
4 x 550 = 2200 (but not more than 2,200)
So False
Thus the correct answer is (D), Total German tourist spending is more than 92% of Total Spanish tourist spending

25. Calculate the cost for each of the options:
2 Australian families = 2 x £236 = £472
2 Spanish families = 2 x £116 = £232
3 German families = 3 x £148 = £444
3 U.S.A. families = 3 x £244 = £732
3 Italian families = 3 x £164 = £492
Thus the correct answer is (D), 3 USA families

26. Whilst it might be tempting to calculate (236 + 116 + 148 + 244 + 164) / 5 = £180, this is not quite correct.
To be able to calculate the average spend per family, we would need to know how many families from each country there are. For example there might be a lot more families from one country which would distort the overall average.
Thus the correct answer is (D), Cannot tell from data
