Answer 1

We dont know CP but total CP=CP+200000+90000

Total CP=CP+290000

And she got 12.5% on selling flat for 900000

So we can form an equation that

TotalCP+12.5%of totalCP=900000.

By this we get CP which is 510000.

Answer can be rechecked by putting the value of CP in the equation.

Rest is in the pic.

Answer 2

Rs 510000
