Question

Shiv went to a restaurant and ordered a pizza when he saw the bill he was surprised to notice that it was Rs 330 which was 10 percent more than the bill he got last time. What was the previous price of the pizza?

a) Rs 300
b) Rs 305
c) Rs 310
d) Rs 315

Answer 1

To find the original price of the pizza before the 10% increase, we solve the equation 1.10P = Rs 330, which results in the original price being Rs 300.

Step-by-step explanation:

The student is asking to find the original price of the pizza before an increment of 10%, which resulted in a final bill of Rs 330. To find the original price, we can set up the equation where the original price (let's call it P) plus 10% of P equals Rs 330. Mathematically, this would be written as P + 0.10P = Rs 330. This simplifies to 1.10P = Rs 330. Dividing both sides by 1.10 gives us the original price P = Rs 300. Therefore, the original price of the pizza before the 10% increase was Rs 300.
