Answer 2

Answer:

5 rupees=3 chocolates ,50 p= 3 chocolates , 25 p= 14 chocolates

Step-by-step explanation:

Given,

we have to buy 20 chocolates for 20 rupees

3 different kinds

25 p ,50 p and 5 rupees

let us calculate for 25 p

25 p =1 chocolate

1 rupee= 4 chocolate

2 rupees=8 chocolates

3 rupees=12 chocolates

4 rupees=16 chocolates

calculate for 50 p

50 p=1 chocolate

1 rupee=2 chocolates

2 rupee=4 chocolates

calculate for 5 rupees

5 rupees = 1 chocolate

10 rupees= 2 chocolates

15 rupees=3 chocolates

20 rupees=4 chocolates

so,

5 rupee chocolates must be limited to 3 for 15 rupees

remaining 5 rupees must be 25 p and 50 p chocolates

after buying 3 chocolates 17 remaining

if you buy 25 p more chocolates and 50 p less chocolates for 5 rupees

hence,

for 4 rupees=16 chocolates of 25 p

    2 rupees=4 chocolates of 50 p

we need to adjust chocolates to get 17 chocolates for 5 rupees

finally,

3 chocolates for 1.5 rupees     (50 p)

14 chocolates for 3.5 rupees   (25 p)

-------------------------------------------

17 chocolates for 5 rupees

hence,

5 rupees=3 chocolates ,50 p= 3 chocolates , 25 p= 14 chocolates
