Expert Asked on 28th April 2016 in Math Puzzles.
We can solve it mathematically.
Let’s assume that x,y,z chocolates from 1st, 2nd and 3rd stores respectively.
Now, 0.05x + y + 5z= 100
Which simplifies to x + 20y + 100z= 2000
Now, x + y +z = 100
Subtracting we get,
19y + 99z = 1900
y= 100- 99z/19
Now, Z= 19 only.
19 from 3rd store
80 from 1st store .
1 from 2nd store
