Question 86

The ratio of present ages of Ramya and Saurabh is 8:7. After 10 years the ratio of their ages will be 12:11. What is Ramya's present age?

Solution

Let Ramya's present age = $$8x$$ years and Saurabh's present age = $$7x$$ years

According to ques, => $$\frac{8x + 10}{7x + 10} = \frac{12}{11}$$

=> $$88x + 110 = 84x + 120$$

=> $$88x - 84x = 120 - 110 = 10$$

=> $$x = \frac{10}{4} = 2.5$$

$$\therefore$$ Ramys's age = $$8 \times 2.5 = 20$$ years

=> Ans - (A)
