First, calculate the amount remaining after the first year, accounting for an x% loss:
This simplifies to:
The amount Y1 is then subjected to a 5x% growth in the second year:
Substituting the expression for Y1 yields:
The problem states that the total value after two years represents a 35% gain. Therefore:
Substituting to solve for x:
The equation is solved as follows:
Combining like terms and solving for x yields:
Consequently, the percentage of loss in the first year is 10%.
