Number Properties : Framing Equations
The question is an elementary Number Systems question and involves operations on numbers by framing a simple equation.
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?
Correct Answer - 1590
. Choice (5)
Let the number that Anita wanted to multiply be 'X'.
She was expected to find the value of 35X.
Instead, she found the value of 53X.
The difference between the value that she got (53X) and what she was expected to get (35X) is 540.
i.e., 53X - 35X = 540
or (53 - 35) * X = 540
X = 30
Therefore, the correct product = 53 * 30 = 1590
