Question
The average of the current ages
of 'Anoop', 'Bhanu', and 'Rakesh' is 40 years. Their ages are in arithmetic progression (AP), with 'Anoop' being the youngest and 'Rakesh' the oldest. Determine the ratio of the ages of 'Bhanu' and 'Dinesh', 8 years from now, given that 'Dinesh' is currently 24 years old.Solution
ATQ,
If 3 (odd) numbers are in AP then middle term will be its average. As ‘Anoop’ is youngest and ‘Rakesh’ is eldest among them So ‘Bhanu’ will be in middle So, age of ‘Bhanu’ = 40 years Required ratio = (40 + 8) : (24 + 8) = 48:32 = 3:2
