Kamal has 160 toffees. He gave 5% toffees to Ravi, 15% toffees to Anita and one-fourth of the toffees to Gagan. How many toffees are left with Kamal after the distribution ?

Answer: Option C

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
