In schod canteen 30 pupils bought each. by 5 pie In canteen left 10 times less pie than pupil bought How many pie were in schod conteen

Let's carefully analyze the problem: - There are **30 pupils**. - Each pupil bought **5 pies**. - After buying the pies, the canteen has **10 times fewer** pies left than the total pies the pupils bought. Let’s define variables: - \( P \) = total pies originally in the canteen. Step-by-step solution: 1. **Calculate the total pies bought by pupils:** \[ \text{Total pies bought} = 30 \times 5 = 150 \] 2. **Determine pies left:** The cans are left with 10 times fewer pies than those bought, meaning: \[ \text{Pies left} = \frac{1}{10} \times 150 = 15 \] 3. **Total pies initially in the canteen:** \[ P = \text{pies bought} + \text{pies left} = 150 + 15 = 165 \] **Final answer:** \[ \boxed{165} \] There were **165 pies** in the school canteen initially.
