Question: Anita had to do a multiplication. Instead of taking 35 as one of the multipliers, she took 53. As a result, the product went up by 540. What is the new product?

Solution:
Let the other multiplier be x.

According to the question,
The original product should have been = 35x
The new product obtained = 53x

The difference between the products is 540.
53x - 35x = 540
⇒ 18x = 540
⇒ x = 540 / 18
⇒ x = 30

∴ New product = 53x
= 53 × 30
= 1,590
