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?${\text{A}}{\text{. }}1050 \\ {\text{B}}{\text{. }}540 \\ {\text{C}}{\text{. }}1440 \\ {\text{D}}{\text{. }}1590 \\$

Hint: Here we go through by assuming the second number as ‘x’ from which we have to multiply our number. And then multiply it by the given number 35 and 53 and in the question the difference is given for both the number. So we will make the equation from that number and get the result.

$\Rightarrow 53x - 35x = 540 \\ \Rightarrow 18x = 540 \\ \Rightarrow x = \dfrac{{540}}{{18}} = 30 \\ \therefore x = 30 \\$
i.e. $53 \times 30 = 1590$.
