• A. 600 followers
• B. 700 followers
• C. 625 followers
• D. 500 followers

Answer 1

The correct option is C 625 followers

The content creator adds 5000 followers every 2 h.
1 hour has 60 minutes.
So, 2 h = $2\times 60=120mins$

∴ Number of followers added every min will be = $\frac{5000}{120}=\frac{500\times 10}{12\times 10}=\frac{500}{12}$

The numbers of followers added every 15 mins will be = $\frac{500}{12}\times 15=\frac{500\times 15}{12}=\frac{500\times 5}{4}=125\times 5=625$

So, the number of followers added every 15 minutes will be = 625.
