Answer 1

He lose money 45% of the money.

Answer 2

Benjamin lose money on this share of stock and the amount of loss is $0.45P$ dollar

Explanation

Original value of the share of stock is P dollar and on the next day, the value of the stock decreased by 50%. So...

The value of the stock on second day $=P- (P*0.50)= P-0.50P =0.50P$ dollar

Now on the third day, he sold the share at 10% more than its value on the second day.

So, the value on third day $=0.50P+(0.50P*0.10)= 0.50P +0.05P = 0.55P$ dollar

As the original value was P dollar and he sold the share at 0.55P dollar and $0.55P< P$, that means he lose money on this share of stock and the amount of loss is $(P-0.55P)dollar = 0.45P$ dollar
