Question

70 coins of 10 paise and 50 is kept in a purse total is 19 rupees. find the no. of 10 and 50 paise coins​

Answer 1

Answer:

30

Step-by-step explanation:

let the number of 10 paise coins be x

then 50p coins=70-x

1 ruppee=100paise

19 ruppee=1900 paise

according to question

10(x)+50(70-x)=1900

10x+3500-50x=1900

-40x=1900-3500

-40x=-1600

1600=40x

1600/40=x

40=x

so,10p coins=40

50p coins=70-40=30
