Key Points
Calculation:
5 years ago the average age of the four-person is 45 year, at present average age of four people = (45 + 5) = 50 yr
Total present age of the four people = (50 × 4) = 200 yr
Total present age of the five people = (49 × 5) = 245 yr
So, age of E = (245 - 200) = 45 yr
∴ The correct answer is 45 years
