I came across this post on 9GAG recently. Was amused initially, then became sad.

My brother teaches high school math. This is how he gets his students to pay attention

Posts like these really makes me sad.....Marie Curie used to say "If you want to lead a happy life attach it to goals instead of people"...But sadly most people these days after the popularization of the social media do the reverse.....But on the brighter side educational websites like Brilliant are inspiring the young generation to travel in the right path and surely one day most people will be doing the right thing by helping others and also by pushing the frontiers of human knowledge instead of wasting time on people who are famous for being famous.......

In 2 mins K's fan following increased by 28

in 2 mins J's following increased by 21

so 7 gap of 7 followers is filled in 2 mins

at 9 AM gap to fill of 1835484 followers

so gap will be filled in 262212 minutes

I don't like people who always ask how math is used in real life. I will present this.

I might be impressed when typical teenagers actually use math to solve this. They would start seeing that math is not just doing what teachers say, but knowing what they're doing.

364 days should be the answer. Think of it this way- Justin has - • 15921292 followers currently • 10.5 followers every minute

Kim has- • 14085811 followers currently • 14 followers every minute

Thus the equation- 15921292 + (10.5 × K) = 14085811 + (14 × K)

Where K = number of minutes until equal (constant for both)

Thus K = 524423 minutes = 364 days (almost 1 year)

Kim Kardashian will need approx. 364 days to be able to match up to Justin Bieber's follower count. This is so sad.

For simplicity, call 'em J and K. in 2 minutes, J got 21 followers, K got 28 followers. So, K gains 7 followers per minute. Initially, J had 15921292-14085811 more followers ie, 1835381... So, in 1 min, K gains 7/2 followers than J, so in 1835381/7*2/60/24days both will be equal. Almost 364 days,ie an year!!
