Solution

The correct option is C Rs 3600
In a given problem
discount d1=15% and d2=5%
Let marked price be M.P and Selling Price be S.P
The formula will be
M.P(1d1100)(1d2100)=S.P
implies that,
M.P=2907(115100)(15100)
M.P=29071720×1920
M.P=2097×20×2017×19
M.P=9×20×20=3600
Therefore the marked price is Rs3600
