1. **State the problem:** Bhanu paid Rs 200 for a book and got Rs 35 as change. Later, she bought a pen for Rs 10. We need to find how much money Bhanu spent in total at the bookshop. 2. **Understand the transaction for the book:** If Bhanu paid Rs 200 and got Rs 35 back, the actual cost of the book is the amount paid minus the change received. 3. **Calculate the cost of the book:** $$\text{Cost of book} = 200 - 35$$ 4. **Simplify the expression:** $$\text{Cost of book} = \cancel{200} - 35 = 165$$ 5. **Add the cost of the pen:** $$\text{Total spent} = 165 + 10 = 175$$ 6. **Conclusion:** Bhanu spent Rs 175 in total at the bookshop. **Final answer:** Rs 175 (Option B)
