      Solution

      ATQ,

      Given: Total toffees = 60, A has 25 toffees, C has 5 less than B. Let B have x toffees, So C has x − 5. Equation = 25+x+(x − 5) = 60. Solving gives x = 20. B = 20 toffees, C = 15 toffees. To make the ratio 5:4:6, let y be the toffees added to C. Equation = [(15+y)/6] = 5, solving gives y = 15.
