So according to the question,
 let x be the no of coins
so,
3X+5X+7X=155 (the total no of coins equal to rs.155)
15x=155
x=155/15
x=10.3
so,
3X= 3*10.3=31(approx.)
5X=5*10.3=52(approx.)
7X=7*10.3=72(approx.)
THEREFORE THE BAG CONTAINS
THIRTY ONE(31) 1 RUPEES
FIFTY TWO(52) 50 PAISE
SEVENTY TWO(72) 10PASIE
and there after
31+52+72=155
0
YOU HAVE TAKEN X COINS OF EACH TYPE WHICH WOULD NOT BE RIGHT 
IT IS BCOZ THE VALUE OF COINS DIFFERS
yes.. i have taken X.. and the values are differing
BUT IT IS NOT RIGHT AS THERE WOULD BE 25 COINS OF EACH TYPE
but you cannot have points also..

THERE WERE 25 COINS OF EACH TYPE
AS 3×1×25=75
   5×0.5×25=62.5
   7×0.1×25=17.5
NOW,ADDING 75+62.5+17.5=155
1 5 1
then you cant have points for your answer...
