Answer:  0.6 in 10 % ; 0.4 in 15 %

Step-by-step explanation:

1. (x*10%) + (y*15%)/ x+y=12%

2. x+y = 1  x= 1-y

(0.1x + 0.15y/ x+y= 12/100) * 100

(10x + 15y/x+y = 12)*(x+y)

10x+15y= 12x + 12y

-2x=-3y

2x = 3y   2(1 - y)= 3y

2-2y=3y   2= 5y

y= 0.4

x= 0.6

A person has 100 notes of Rs. 10 and Rs. 20 each. He went to a shop and bought items for Rs. 220. In how many ways can he pay th
Alekssandra [29.7K]

There are 12 ways he can pay this amount using the notes he has the answer is 12.

<h3>What are permutation and combination?</h3>

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.
