Answer 1

Answer:

What is the hardest math problem in the world?

Today's mathematicians would probably agree that the Riemann Hypothesis is the most significant open problem in all of math. It's one of the seven Millennium Prize Problems, with a million dollar reward for its solution.Sep 26, 2019

Step-by-step explanation:

What is the 1 million dollar math problem?

To date, the only Millennium Prize problem to have been solved is the Poincaré conjecture, which was solved in 2003 by the Russian mathematician Grigori Perelman. He declined the prize money.

Answer 2

$answer \: given \: \\ hope \: it \: helps$

Let the money with man be x

⇒20% is lost

⇒0.8x is remaining

∴75% of 0.8x is 480 ............. Because 25% s spend

⇒

$\frac{75}{100} \times 0.8x \: = \: 480 \\ x = 800$
