If
a = number of 1 rupee coins
b = number of 50 paise coins
c = number of 25 paise coins
d = number of 10 paise coins


then four equations are
a+b+c+d = 325
d/a = 4/3 or d= a*4/3
100a= 5*50*b or b= a*2/5 as The value of a 1 rupee coins is 5 times the value of 50 paisa coins.
b=c/4 as There are as many 50 paisa coins as the value of 25 paisa coins in a rupee

solving these eqns, we get
a=75 coins
d=a*4/3= 75*4/3=100..... answer
b= 75*2/5= 30
c=4b = 120

The equations i got:
a = number of 1 rupee coins
b = number of 50 paise coins
c = number of 25 paise coins
d = number of 10 paise coins

so :
total number of coins in the bag is 325
1) a+b+c+d = 325
ratio of the number of 10 paisa coins to that of 1 rupee coin is 4:3
d/a = 4/3
2) 3d = 4a
The value of a 1 rupee coins is 5 times the value of 50 paisa coins
a = 5 * 2d
3)a= 10d
There are as many 50 paisa coins as the value of 25 paisa coins in a rupee
4) b =4c

I got these 4 equations however I am not getting a value
