Question
The combined present ages of Ramesh and Suresh amount to 68
years, while the sum of Ramesh and Vivek's current ages is 82 years. Additionally, in 10 years, the age ratio of Ramesh to Vivek will be 25:26. Find the Suresh's present age.Solution
Sum of ages of Ramesh and Vivek after 10 years = 82 + 10 × 2 = 102 years
So, age of Ramesh after 10 years = [25/(25 + 26)] × 102 = 50 years
Therefore, present age of Suresh = 68 – (50 – 10) = 28 years
