Step-by-step explanation:
first way ,10 x 22 = 220
second way , 20 x 11 = 220
There are many ways other than this but I cant tell all of them. for example, the person can just give Rs. 1000 to the shopkeeper and receive a change of Rs. 780
There are 12 ways he can pay this amount using the notes he has the answer is 12.
What are permutation and combination?
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
Let x be the number of Rs10 notes and y be the Rs20 note
10x + 20y = 220
The whole number of x and y which satisfy the above equation:
x = 0, y =11
x = 2, y =10
x = 4, y =9
x = 6, y =8
x = 8, y =7
x = 10, y =6
x = 12, y =5
x = 14, y =4
x = 16, y =3
x = 18, y =2
x = 20, y =1
x = 22, y =0
Total number of ways = 12
Thus, there are 12 ways he can pay this amount using the notes he has the answer is 12.
