5 year hence, ratio of ages of A and B will be 7 : 5 and difference between their ages will be 4 years. What are present ages (in years) of A and B respectively?
Let ages of A and B five years later be $$7x$$ and $$5x$$ years respectively.
According to ques, => $$7x-5x=4$$
Thus, A's present age = $$7(2)-5=9$$ years
B's present age = $$5(2)-5=5$$ years
=> Ans - (C)
