  4. $Rs.1,27,500$

Ans A.

Total floor area $= 3850$ sq.mts

Total area to be carpeted $= 3850-550 = 3300$ sq.mts

Carpet cost $=$ Rs $50/$sq.mts

Total cost to carpet $3300$ sq.mts $= 50 \times 3300 = \text{Rs. } 1,65,000$

Area=70*55sq.mts=3850sq.mts

Total area to be carpeted(leaving the area for flower pots)=3850-550=3300 sq.mts.

Total cost= 3300*50=Rs.165000.
