According to the question
4x+45x+4=14174x+45x+4=1417
68x + 68 = 70x + 56
2x = 12 = > x = 6
Hence, present age of B = 5 x 6 = 30 yr
Let's the common factor of present ages be x .
Then, the present ages of A and B be 4x and 5x respectively.
After, four years the ages of A&B shall become,4x+4 and 5x+4 respectively,
According to given , the ratio of ages of A and B is 14:17,
So,4x+4/5x+4 =14/17
68x+68=70x+56
70x-68x =68-56
2x=12
X=12/2
=6
Therefore, B's present is 5x =5❌6
=30years.
Thank you!
