Answer:
Therefore the number of rs.5 coins =z=7
the number of rs.2 coins=3z=3*7=21
the number of rs.5 coins=260-4z=260-4(7)=260-28=232
Step-by-step explanation:
Let the number of rs.5 coins be z
Money in rs.5 denomination=5z
So the number of rs.2 coins=3z
Money in rs.2 denomination=2(3z)=6z
The total number of coins=260
The number of rs.1 coin=260-(3z+z)=260-4z
Money in rs.1 denomination=260-4z
Total money=309
5z+6z+260-4z=309
7z+260=309
7z=309-260
7z=49
z=7
Therefore the number of rs.5 coins =z=7
the number of rs.2 coins=3z=3*7=21
the number of rs.5 coins=260-4z=260-4(7)=260-28=232
