OUT OF THEM THE FIRST TWO TYPES OF PULSE ARE MIXED IN THE RATION OF 2:3. IN WHAT RATIO THE THINRD TYPE OF PULSE SHOULD BE MIXED SO THAT THE COST OF MIXTURE WILL BE RS.78 PER KG?Answer by palanisamy(496)   (Show Source): You can put this solution on YOUR website!A SHOPKEEPER HAS THREE TYPES OF BLACK PULSE COSTING RS.60, RS.72 AND RS.90 PER KG RESPECTIVELY. THE FIRST TWO TYPES OF PULSE ARE MIXED IN THE RATION OF 2:3. lET THE THIRD TYPE PULSE BE MIXED IN THE RATIO x THE FINAL COST OF THE MIXTURE IS RS.78 PER KG THEREFORE, WE GET (2X60)+(3X72)+90x = (2+3+x)X78 120+216+90x = (5+x)X 78 336+90x = 390+78x 90x-78x = 390-336 12x = 54 x = 54/12 x = 9/2
