What’s the difference between the average precipitation in Tirana and Algiers?

Answer: 68

Explanation: First, we work out the average precipitation for each location: Tirana (135+150+130+115+120)/5 = 130 Algiers (80+75+55+60+40)/5 = 62 Then we subtract the smallest from the largest to find the difference: 130 - 62 = 68

There was an error in the calculations of the precipitation levels in Stockholm. The figure recorded in February is 15% higher than it should be. What’s the new percentage change in precipitation from February to March in Stockholm?

Answer: 41%

Explanation: We need to calculate how much is 15% out of 25. (25x15)/100= 3.75 So the actual figure is 25 - 15% = 25 - 3.75 = 21.25 Hence using the percentage change (increase) formula, there is a (30-21.25)/21.25 = 0.41 = 41%

What proportion of Val Thorens' snowfall occurred in January?

Answer: 5%

Explanation: Step 1: Calculate the total snowfall in Val Thorens across the 4 months. 5cm + 20cm + 40cm + 35cm = 100cm Step 2: Divide the January value by the total and multiply by 100 to calculate the amount as a percentage. 5cm / 100cm x 100 = 5%

What was the percentage increase in snowfall in Whistler from November to December?

Answer: 50%

Explanation: Step 1: Identify how much snow fell in Whistler in November and December: Nov = 20cm Dec = 30cm Step 2: Calculate the difference between the two amounts: 30cm -20cm = 10cm Step 3: Divide the difference by the November figure 'the old figure' and multiply by 100. 10cm / 20cm x 100 = 50% Tip: To calculate the percentage increase quickly: Subtract the newest figure from the oldest figure and divide by the oldest.

If total snowfall for the following January was predicted to increase by 20% from December in Val Thorens and Whistler and decrease by 15% in Tignes and Les Arcs, what would be the total snowfall across all the resorts next January?

Explanation: Step 1: Calculate a 20% increase in the December snowfall in Val Thorens and Whistler: (30cm + 35cm) × 1.2 = 78cm Step 2: Calculate a 15% decrease in the December snowfall in Tignes and Les Arc: (20cm + 30cm) × 0.85 = 42.5cm Step 3: Add the two values together: Total = 120.5cm

How much snow fell in Whistler and Les Arcs in January and February combined?
