If what you mean by the "percent of people 50 years old belong to group A" is the percentage of 50-year old people with respect to the total number of people belonging to group A, then the answer is

32/(19+32) 100 = 63%

But, if what you mean is the percentage of 50-year old people in group A with respect to the total number of 50-year old people, then the answer will be

32/(32+24) 100 =  57%
