Let 'x' be the percentage of abundance of isotope of mass 37,
Hence '100-x' is the percentage of abundance of the isotope of mass 35.

Now,
37 (x/100) + 35(100-x/100) = 35.5
37x/100 +35 - 35x/100 = 35.5
2x/100 = 0.5
x=25%

Therefore the abundance of isotope of mass 37 is 25% while that of isotope of mass 35 is 75%.
