Mathematics time 2.

Today, I will be explaining how to calculate year of birth.

Q2: If a social media platform is 443 years old in 2025:

(a) which year was it established?

(b) how old was it in 1994?

(c) what is the age difference between 1994 and 2025?

Solution

(a) Its year of establishment is known as the year of birth = current year — current age.

Current year = 2025.

Current age = 443.

Year of establishment = 2025 — 443 = 1582.

(b) current age = current year — year of birth.

Current age in 1994 = 1994 — 1582 = 412 years old.

The social media platform was 412 years in 1994.

(c) the age difference between 1994 and 2025 = (age in 2025) — (age in 1994)

But the age in 2025 = 443 years.

Age in 1994 = 412 years

Time difference = (443 — 412) = 31 years.
