Explanation:

- Let's assume the total number of toffees is \(x\).

- Wasted Toffees: \(1/10\) of the toffees are wasted, so wasted toffees = \(x/10\).

- Toffees for N: \(1/8\) of the total toffees are given to N, so toffees for N = \(x/8\).

- Equation: N's toffees are 10 more than the wasted toffees: \(x/8 = x/10 + 10\).

- Solving the equation:

$$

x/8 - x/10 = 10

$$

$$

5x/40 - 4x/40 = 10

$$

$$

x/40 = 10

$$

$$

x = 400

$$

- Remaining Toffees: After waste, \(9x/10 = 360\) are left.

- Toffees for S: 35% of remaining toffees = \(0.35 \times 360 = 126\).

- Option 1: 126 (This is the correct answer).

- Option 2: 150

- Option 3: 110

- Option 4: 135
