To find :
Number of each type of notes
Solution :
Let x denote = Rs. 10
Total notes = 15
Number of notes of Rs. 20 = (15 - x)
Total money = Rs. 200
➨ 10x + 20 (15 -x) = 200
➨ 10x + 300 - 20x = 200
➨ 10x - 20x = 200 - 300
➨ -10x = -100
➨ 10x = 100
➨ x = 100 / 10
➨ x = 10
No. of notes of Rs. 10 = 10
No. of notes of Rs. 20 = (15 - x)
➨ (15 - 10)
➨ 15 - 10
➨ 5
