Question

To coins of 10 paise and 50 paise are mixed in a purse.If the total value of the money in the purse is Rs.19. find the number of each type of coins.​

Answer 1

Answer:

50 paisa coins: 10 paisa coins= 9:2

Total amount= 19 Rs or 1900 paisa

10(9x)+ 50(2x)= 1900

90x+ 100x= 1900

190x= 1900

X= 1900/190

X= 10

10 paisa coins= 9(10)= 90 coins

50 paisa coins= 2(10)= 20 coins

VERIFY:

10 coins of 10 paisa constitute 1 rupee.

So, 90 coins of 10 paisa:

90/10

= Rs 9

2 coins of 50 paisa constitute 1 rupee.

So, 20 coins of 50 paisa:

20/2

= Rs 10

Now, we add both the rupee values.

Rs 9+ Rs 10= Rs 19

Rs 19= Rs 19

LHS= RHS

Hence, verified
