1. The Smiths are investigating irregularities in their household bills. Below are two charts
analysing these payments:


How many bi-monthly electricity bills of Smith household are higher than the national
average?

A. 0
B. 1
C. 2
D. 3
E. 4


Explanation

The national average of a bi-monthly electricity bill is £500 (green column).
The Smiths' bi-monthly electricity bill of Jan+Feb was £450 (blue column).
The chart on the right informs us about changes of the bi-monthly electricity bill relative to the Smiths' Jan+Feb bill.
Therefore, not every increase necessarily represents a higher payment than the national average.
Note that the bills of Sep+Oct and Nov+Dec were lower than that of Jan+Feb, and thus cannot be higher than the
national average, given that Jan+Feb's were already lower than the national average. Therefore, they can be eliminated
from the start.
The electricity bill of Mar+Apr was 10% higher than that of Jan+Feb:
110% of £450 = 1.1 x 450 = £495 < 500%. This is not higher than the national average.
The electricity bill of May+Jun was 20% higher than that of Jan+Feb:
120% of £450 = 1.2 x 450 = £540 > 500%. This is higher than the national average.
The electricity bill of Jul+Aug was 25% higher than that of Jan+Feb. It is a higher figure than the previous bi-monthly bill,
thus we already know it is higher than the national average and we don't need to calculate the actual sum.
