Question

The sum of ages of anup and father is 100. When anup is as old as his father now, he will be 5 time as old as his son anuj now. Anuj will be 8 years older than anup is now , when anup is as old as his father. What are their ages now?

Answer 1

anup + father = 100      ,    anuj = ?
after   father - anup    number of years,   
   father = 5 * anuj
        =>  anup + 5 anuj = 100   
   anuj + father - anup = 8 + anup
        =>  6 anuj - 2 anup = 8 
anuj = 208/16 = 13 yrs
anup = 35 yrs
father = 65 yrs
