Question
Two years from now, Pankaj's age
will be of Bheem's current age and 80% of Raju's current age. The ratio of Bheem's age to Raju's age is 6:5. Determine how many years ago Pankaj's age was half of Raju's age.Solution
ATQ, Let Pankaj’s present age = ‘p’ years So, Bheem’s present age = (p + 2) × (300/200) = [(3p + 6)/2] years And Raju’s present age = (p + 2) × (100/80) = [(5p + 10)/4] years From the question: [(3p + 6)/2]/[(5p + 10)/4] = 6/5 (12p + 24)/(10p + 20) = 6/5 2p + 4 = 2p + 4 Since we cannot find the present age of any of them. So, the answer cannot be determined
