Let marked price = Rs. $$100x$$ After 1st discount of 10%, selling price = $$100x-(frac{10}{100} imes100x)=Rs.$$ $$90x$$ Similarly, after 2nd discount of 20%, selling price = $$90x-(frac{20}{100} imes90x)=Rs.$$ $$72x$$ According to ques, => $$72x=1764$$ => $$x=frac{1764}{72}=24.5$$ $$ herefore$$ Cost price = $$frac{50}{100} imes100 imes24.5=Rs.$$ $$1225$$ => Ans - (A)
