Let list price = Rs. $$100x$$ After first discount of 20%, price = $$100x imes frac{(100-20)}{100}=80x$$ After second discount of 10%, price = $$80x imes frac{(100-10)}{100}=72x$$ After third discount of 30%, price = $$72x imes frac{(100-30)}{100}=50.4x$$ => Equivalent discount = $$frac{100x-50.4x}{100x} imes 100$$ = $$49.6\%$$ => Ans - (B)
