   D. None of the Above
   
   Answer & Explanation

   Answer – D. None of the Above
   Explanation :
   Present age of Veena’s son = x
   Veena’s present age = 3x
   Veena’s present age = 2/5 of Father’s present age
   Father’s present age = (15/2) x
   Total present age = x + 3x + (15/2)x = 138
   x = 12
   Difference between Veena’s father’s present age and Veena’s son’s present age = 90 – 12 = 78 years.
   
   
2. Five years ago, the age of Abinav was 4 times the age of Sarita after 10 years, Abinav will be twice as old as Sarita. Find the Present ages of Abinav and sarita?
   A. 30 years, 10.5 years
   B. 32 years, 11.5 years

   Answer & Explanation

   Answer – D. 35 years, 12.5 years
   Explanation :
   Five years ago,
   x – 5/y – 5 = 4/1
   x – 4y = – 15 —-(i)
   After 10 years,
   x + 10/y + 10 = 2/1
   x – 2y = 10 —–(ii)
   From eqn (i) and (ii) => x = 35, y = 12.5
   
   
3. If Saurabh is as much elder than Shyam as he is younger to Suresh and sum of the ages of Shyam and Suresh is 46 year, then what will be the age of Saurabh after five years?

   Then Suresh’s age = x + y
   Shyam’s age = x – y
   (x + y) + (x – y) = 46
   x = 23
   The age of Saurabh after five years is – 28
