Answer: There are 5 candies of first type and 4 candies of second type.
Step-by-step explanation:
Since we have given that
Number of pieces of candy of first type = 15
Number of pieces of candy of second type = 20
We need to find the greatest number of pieces possible.
So, Greatest number of pieces = H.C.F. of 15 and 20 = 5
So, there are 5 greatest number of pieces possible.
Number of candies of first type in this piece = 
Number of candies of second type in this piece = 
Hence, there are 5 candies of first type and 4 candies of second type.
