lets say he bought x,y and z pieces.
Then we can make these two equations
Eq1: x + y + z = 100
Eq2: 5x + 3y + 0.5z = 100

2*Eq2 => 10x + 6y + z = 200
2*Eq2-Eq1 => 9x + 5y = 100
from this equation x should be a multiple of 5, for x = 5 => y = 11
for x = 10 => y = 2
for x = 15 or more y becomes -ve

So two possible answers
x = 5, y = 11, z = 84
x = 10, y = 2, z = 88

    Wow. The grammar here is awful and needs to be rewritten so that it is easier to understand what the actual question is. I had to read it 5 times before I could tell what the question was actually asking, and what information was actually given.

    No. Of pieces of Rs.5 =10
    No. Of pieces of Rs.3 =2
    No. Of pieces of Rs.0.5 = 88
    Total no. Of pieces = 100
    Total cost = (5*10)+(3*2)+(0.5*88)=100
