You are given two ropes with different lengths. However if you set both ropes of fire from the tip, they will both burn at exactly one hour.
You are asked to measure 45 minutes using just these two ropes and you and NOT allowed to cut the ropes at all.
How will you do this?
1. Burn one of the ropes from both ends. The rope will burn completely at half time (i.e. 30 minutes).
2. Also burn the other rope from one end at the same time. At the time rope #1 completely burns, rope #2 will be half length. That is, it now has 30 minutes left to burn.
3. Immediately set the other side of rope #2 on fire too. It will burn at half the time left (i.e. 15 minutes).
4. Let rope #2 burn completely too.
You have successfully measured 30minutes + 15 minutes = 45 minutes.

A project of our size needs at least a few hundred million dollars per year to keep going,” Mr. Durov wrote in his public channel on Telegram late last year. “While doing that, we will remain independent and stay true to our values, redefining how a tech company should operate.
Should You Buy Bitcoin?
In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
