8 years ago, ratio of ages of Arjun and Brijesh was 1:2. And 4 years from now ratio of ages ages of Brijesh and Deepak will be 2:3. Average of current ages of Arjun and Deepak is 27. Find Current Age of Deepak?
Solution (a-8)/(b-8) = 1/2= 6/12 = (a-8+6)/(b-8+12) = (a-2)/b+4) = 1/2 ……(1) (b+4)/(d+4) = 2/3……..(2) (1)*(2) (a-2)/(d+4) = 1/3 no applying componendo (a+d+2)/(d+4) = 4/3 (also given (a+d)/2 = 27….(a+d) = 54) So 56/(d+4) = 4/3 d+4 = 42 d = 28
