Question 93

The ratio of present ages of Rangana and Sayed is 7:5. After 11 years the ratio of their ages will be 4:3. What is Rangana's present age?

Solution

Let Rangana's present age = $$7x$$ years and Sayed's present age = $$5x$$ years

According to ques, => $$\frac{7x + 11}{5x + 11} = \frac{4}{3}$$

=> $$21x + 33 = 20x + 44$$

=> $$21x - 20x = 44 - 33$$

=> $$x = 11$$

$$\therefore$$ Rangana's age = $$7 \times 11 = 77$$ years

=> Ans - (B)
