A shopkeeper is giving two consecutive discount of 30% and 20%. The selling price of an article after discount whose MRP is 1200 is:

600 572 840 672

672

MRP = 1200/- S.P. after 1st discount of 30% = 1200 × 70% = 1200 × \(\frac{70}{100}\) = 840 S.P after 2nd discount of 20%= 840 × 80% = 840 × \(\frac{80}{100}\) = 672/-
