The ratio of present ages of Ranjini and Shahid is 5:4. After 13 years the ratio of their ages will be 6:5. What is Ranjini's present age?
Let Ranjini's present age = $$5x$$ years and Shahid's present age = $$4x$$ years
According to ques, => $$\frac{5x + 13}{4x + 13} = \frac{6}{5}$$
=> $$25x + 65 = 24x + 78$$
=> $$25x - 24x = 78 - 65$$
=> $$x = 13$$
$$\therefore$$ Ranjini's age = $$5 \times 13 = 65$$ years
=> Ans - (B)
