Total no: of notes = 50 No: of ₹20 notes = 50-x Total money denomination by ₹10 = ₹10x Total money denomination by ₹20 = ₹20(50-x) ₹1000-20x Now, according to question:- 10x+1000-20x = 800 10x-20x = 800-1000 -10x = - 200 x = - 200/-10 x = 20 Hence, No: of ₹10 notes = 20 No: of ₹20 notes = 50-20=30 Hope it helps you...
