Study the given table and answer the question that follows.

The table shows the number of voters at three different centres A, B, C.

Centre	Total number of registered voters	Percentage of people who voted (Out of the total number of registered voters)
A	4600	78
B	5400	70
C	6500	85

Number of people who did not vote at centre B is what percentage more than those who did not vote at centre C ?

Given:

Registered voters at Centre B = 5400

Percentage of people who voted at Centre B = 70%

Registered voters at Centre C = 6500

Percentage of people who voted at Centre C = 85%

Formula used:

People who did not vote = Total registered voters - People who voted

Percentage more = ((Difference in people who did not vote) / People who did not vote at Centre C) × 100

Calculation:

People who voted at Centre B = 5400 × 70% = 3780

People who did not vote at Centre B = 5400 - 3780

⇒ People who did not vote at Centre B = 1620

People who voted at Centre C = 6500 × 85% = 5525

People who did not vote at Centre C = 6500 - 5525

⇒ People who did not vote at Centre C = 975

Difference in people who did not vote = 1620 - 975 = 645

Percentage more = (645 / 975) × 100

⇒ Percentage more = 66 ²/₁₃ %.

∴ The number of people who did not vote at Centre B is 66 2/13   more than those who did not vote at Centre C.
