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.
