Sir ans sahi nahi h
Sorry l have mentioned wronlgly that same logic have been applied for 1st and 3rd column but it should 2nd and 3rd column. And another mistake i.e. diffrent logic for 2nd column but it should 1st column.
How it becomes 42? You have applied one logic for 1st and 3rd column but different logic for 2nd column. For reasoning logic should be same for three column.
