      D 48 Correct Answer Incorrect Answer

      Solution

      Let the usual speed of Ankit be 'v' km/h and usual time taken to reach office be 't' hours.So, v X t = 0.8v X [t + (8/60) ]Or, 5t = 4 X [t + (2/15) ]Or, 5t = 4t + (8/15)Or, 't' = (8/15)Therefore, required time = (8/15) X 60 = 32 minutes
