Can you tell now how many 20 and 25 paise she got?

Answer of the puzzle Can you tell now how many 20 and 25 paise she got? is :  200 and 124

How:-

Lets say x is the count of 20 paisa and y is the count of 25 paisa so

x + y = 324

that also means x = 324 – y

we know that value of x is 20 paisa and y is 25 paisa so

20 . x + 25 . y = 7100

now replace the x (324 – y)

20 . (324 – y) + 25 y = 7100

6480 – 20y + 25y = 7100

5y = 7100 – 6480

5y = 620

y = 124

so x = 324 – 124 = 200
