Hi Harsh

Once  you get the Logic that the Average is nothing but Total age divided by Number of People, you don't have to write each step. Instead you can just write the total and it won't be as difficult as it looks with step by step calculation. Here you can simply  write Couple's age Total , then Total age after twins and Total age after third child and by looking at their differences in total age you can get their age and time period. 1 increase in Average of 4 people means increase of 4 in Total Average(4/4 = 1).

Thankyou
