Worked solution

6(a)

1. Find the number of complete repetitions of the word 'RESILIENCE' in the first 100 letters

The word 'RESILIENCE' has 1010 letters.
Number of repetitions = 100÷10=10100 \div 10 = 10

2. Calculate the total number of 'E's

There are 33 'E's in each word 'RESILIENCE'.
Total number of 'E's = 10×3=3010 \times 3 = 30

Answer

3030

6(b)

1. Find the number of complete repetitions of the word 'RESILIENCE' needed to get close to 101 'E's.

Each word has 33 'E's.
101÷3=33101 \div 3 = 33 with a remainder of 22.
This means there are 3333 complete words, which contain 33×3=9933 \times 3 = 99 'E's.

2. Calculate the total number of letters up to the 101st 'E'.

The 3333 complete words contain 33×10=33033 \times 10 = 330 letters.
The remaining 22 'E's must be found in the 3434th word.
In the word 'RESILIENCE', the 22nd 'E' is at the 77th position.
Total letters = 330+7=337330 + 7 = 337.
