ANSWER
The ratio of Hari's and Harry's present ages is 5:7
So, let their ages be 5x and 7x
After 4 years their ages will be in ratio 3:4
Therefore,(5x+4)/(7x+4)=3/4
or, 4(5x+4)=3(7x+4)
or, 20x+16=21x+12
or, 16−12=21x−20x
or, 4=1x
or, x=4
Therefore, present age of Hari = 5x=(5×4)=20 years.
Present age of Harry =7x=(7×4)=28 years
The sum of their age is 28+20=48years
