Question : The given pie charts represent the popularity of ice-cream flavours in the years 2005 and 2015.
If a percentage point shift results in annual additional sales of Rs. 5,000, how much (in Rs.) did the combined annual strawberry and butterscotch sales increase from 2005 to 2015?
Option 1: 74,000
Option 2: 37,000
Option 3: 65,000
Option 4: 10,000
Correct Answer: 37,000
Solution :
From the pie charts,
The popularity of strawberry flavour increased from 18.9% in 2005 to 20.5% in 2015, a shift of 1.6 percentage points.
The popularity of butterscotch flavour increased from 10.8% in 2005 to 16.6% in 2015, a shift of 5.8 percentage points.
The combined shift in popularity for strawberry and butterscotch flavours = 1.6 + 5.8 = 7.4 percentage points
Given that a percentage point shift results in annual additional sales of Rs. 5,000.
The combined annual increase in sales for strawberry and butterscotch flavours from 2005 to 2015 = 7.4 × 5000 = Rs. 37,000
Hence, the correct answer is 37,000.
