Answer 1

plzz correct the data . I don't thik it is right. plz recheck and put a comment about it
I think there must be 25p in place of 20p
then number of coins will be rupee= 375
50p= 600
and 25p= 300
if the answer is right then your question is wrong.
other wise the ratio must be 5:8:5

Answer 2

Hi bro!

Here is your Answer!

let the total number of coins be X

so

1 rs coins be = 5x
50p coin's be = 8x.
20 pcoins be = 4x


now convert 1 Rs into paisa

1 Rs = 100p


then

5x*100+8x*50+ 4x*20 = 75000
500x + 400x +80x = 75000

980x = 75000
X = 75000/980

X = 76.53

1 Rs coins = 5×76.53=382.65
50 p coins=8×76.53= 612.24
20 p coins = 306.12
