This problem can be solved easily by multiplying the time of the life expectancy of the coin with the fraction 1/20. The solution is as follows:
<span>Life expectancy of circulating paper money = 25 years * 1/20
</span><span>Life expectancy of circulating paper money = 1.25 years or 1 and 1/4 years</span>

Now the theorem to use is that , the exterior angle of a triangle is equals the sum of the two opposite interior angle.
Thus, mathematically;
3x + 11 + 3x + 15 = 10x -14
6x + 26 = 10x -14
10x-6x = 26 + 14
4x = 40
x = 40/4
x = 10
