Correct Answer - Option 4 : 32
Calculations:
Total One BHK flats in all the buildings = 20 + 15 + 25 + 24 = 84
Total Two BHK flats in all the buildings = 30 + 35 + 25 + 26 = 116
The difference between total Two BHK flats and total One BHK flats in all the buildings = 116 – 84 = 32
∴ The difference between total Two BHK flats and total One BHK flats in all the buildings is 32
