Solve this:

Hi, 
2;-
Answer :

Let  ratio coefficient  =  x 

And ratio of 1 rupee , 50 paise and 10 paise coins  3  : 5  : 7 

So,

1 rupee coins  =  3 x 

50 paise coins  =  5 x 

And

10 paise coins  =  7 x 

And total money  =  155 , So

1 ( 3 x  ) + 0.5 ( 5 x  ) + 0.1 ( 7 x  ) =  155

3 x + 2.5 x  + 0.7 x =   155

6 . 2 x  =  155

x  =  25

So,

1 rupee coins  =  3 ( 25 ) =  75 

50 paise coins  =  5 ( 25 ) =  125  

And

10 paise coins  =  7 ( 25 ) = 175                                                   ( Ans)
