D. 79

E. None of these

Answer: Option C

Solution(By Examveda Team)

Number of toffees distributed :
= 5% of 160 + 15% of 160 + $$\frac{{1}}{{4}}$$ of 160
= $$ \left( {\frac{5}{{100}} \times 160} \right) + \left( {\frac{{15}}{{100}} \times 160} \right) + $$      $$\left( {160 \times \frac{1}{4}} \right)$$
= 8 + 24 + 40
= 72
∴ Number of toffees left behind :
= 160 - 72
= 88
