A sum of Rs. 8.85 is made up of 124 coins which are either 10 paisa or 5 paisa coins ;how many are of each?

Answer 1

Answer:

Therefore 53 number of 10paise coins and 71 number of 5 paise coins made 885 paise (or) 8.85.

Answer 2

Answer:

10 paisa = 53 , 5paisa = 71

Step-by-step explanation:

₹8.85= 885paisa

let total no of 10 paisa coin = x

let total no of 5 paisa coin = y

10x + 5y = 885 ------eq 1

x + y = 124. -----eq 2

x = 124-y

put value of x in eq 1

10(124-y ) + 5y = 885

1240-10y +5y = 885

-5y = 885-1240

5y = 355

y = 355/5

y = 71

put value of y in eq 2

x + 71 = 124

x = 124-71 = 53
