Let the no. of Rs.50 notes= x Let the no. of Rs.100 note= y A/q x+y=25.........(1) 50x+100y=2000 x+2y=40 (dividing all by 50)...........(2) Now, (1) - (2) By elimination method x+y=25 x+2y=40 .................. -y=-15 => y = 15 Putting y=15 in (1) x+15=25 => x = 25 - 15 => x = 10 Therefore No. of Rs.50 notes =10 No. of Rs.100 notes = 15
