If each UK Internet Searcher spends £1.50 on average per month when buying goods/services online, what is the annual spend of all UK Internet Searchers (to the nearest £million)?


Tip: Remember to multiply the number of Searchers by the percent who actually buy goods/services. The key phrase is "when buying goods/services".

Step 1 – calculate the number of UK Internet searchers buying goods/services online in June

UK’s Internet
Searchers
% of searchers Buying
goods/services
 
31,225,000 22 31,225,000 x 22% =
6,869,500

Step 2 – calculate the annual spend
£1.50 x 6,869,500 x 12 = £123,651,000 = £124 million

So the correct answer is (D) £124 million

In which country was there the second lowest number of Searchers selling goods/services online?


The first table shows the % of Searchers selling goods/services, as well as the number of Internet searchers. Use these columns to find the total number of searchers per country – whilst ensuring that - unlike the previous question – you provide the second lowest number of Searchers.    

                 (1000’s)
Australia: 10% x 19,613 = 1,961.30
Ireland: 3% x 1,146 = 34.38
UK: 12% x 31,225 = 3,747.00
Italy: 6% x 14,850 = 891.00
Sweden: 21% x 16,204 = 3,402.84

Thus the correct answer is (D) Italy

In which country was there the second highest number of Searchers buying goods/services online?


The first table shows the % of Searchers buying goods/services, as well as the number of Internet searchers. Use these columns to find the total number of searchers per country, as follows;
                (1000’s)
Australia: 32% x 19,613 = 6,276.16
Ireland: 28% x 1,146 = 320.88
UK: 22% x 31,225 = 6,869.50
Italy: 8% x 14,850 = 1,188
Sweden: 42% x 16,204 = 6,805.68

Thus the correct answer is (E) Sweden

If the sale price for a Faze laptop is $182.40 in the United States and 255.36 Euros in France, what is the sale price ratio for UK:US:France? (Use exchange rates of 1.2 Euros to the £; and 1.5$ to the £).


Step 1 – use the exchange rates to calculate the sale prices in the US and in France in £.
US sale price = $182.40 /1.5 = £121.6
French sales price = 255.36 /1.2 = £212.8

Step 2 – the Faze sales price in the UK is 2/5 x £380. We now obtain a ratio
UK; US; France = 152:121.6:212.8

Step 3 – simplify the ratio by dividing by the highest common denominator (30.4)
152/30.4 : 121.6/30.4 : 212.8/30.4 = 5:4:7

So the correct answer is (C) 5:4:7

Which of the following would generate the highest total amount at the sale prices shown?


Step 1 – calculate the sales price for the 4 laptops that are listed as possible answer
options, using the column giving sale price fraction of normal price;
              Sale Price (£)
Adele = 350 x 3/4 = 262.5
Faze = 380 x 2/5 = 152
Stunn = 420 x 1/2 = 210
Brete = 650 x 2/3 = 433.33

Step 2 – go through answer options (A) to (E) calculating the total amount
(A) 75 Adele laptops = 75 x 262.5 = £19,687.50
(B) 150 Adele laptops at a price further reduced by 60% = 40% x 150 x 262.5 = £15,750
(C) 50 Faze and 50 Stunn laptops = 50 x (152 + 210) = £18,100
(D) 45 Brete laptops = 45 x 433.33 = £19,499.85
(E) 90 Stunn laptops = 90 x 210 = £18,900.00

So the correct answer is (A) 75 Adele laptops
