Question
The current age ratio of Riya to Renu is 4:7. In eight
years, the combined age of Riya and Renu will total 93 years. What is Riya's current age?Solution
Let present age of Riya and Renu is ‘4x’ years and ‘7x’ years, respectively. According to the question, (4x + 8) + (7x + 8) = 93 Or, 11x = 93 – 16 = 77 Or, x = 7 Present age of Riya = 4 × 7 = 28 years
