Hey mate! Here is your answer.
Ratio of their ages = 6:5
Let their ages be 6x and 5x
Sum of their ages = 66
6x + 5x = 66
11x = 66
x=6
Their age = 6x and 5x
= 6×6 and 6×5
= 36years and 30 years
After y years, their ages' ratio = 8:7
36+y/ 30+ y = 8/7
7(36+y)=8(30+y)
252 + 7y = 240 + 8y
252- 240 = 8y - 7y
y = 12
Answer is -: After 12 years their ages would be in the ratio 8:7
