I got this question during an internship interview.

I need to ask this question from Applications of Linear Equation (Create and Solve the Equations) topic in division Linear Equations in One Variable of Mathematics – Class 8

Answer 1

The correct choice is (a) 5

The explanation: Let the number subtracted be x.

484 – x = 459

∴ 484 – 459 = x

∴ x = 25

∴ the subtracted number is 25 and 25 is square of number 5.
