Question : If x + y = 36, then find (x – 27)3 + (y – 9)3.
Option 1: 1
Option 2: 81
Option 3: 2y
Option 4: 0
Correct Answer: 0
Solution : $x + y = 36$ Formula used: $a^3 + b^3 = (a + b)(a^2 - ab + b^2)$ $⇒ x + y = 36$ $⇒ x + y - 36 = 0$--------(1) $⇒ (x - 27) + (y - 9) = 0$ Let's consider $(x
Question : Directions: The following figure shows the number of students (in thousands) admitted and passed out per year in a college during the years 2000-2004. Follow the figure and answer the question.
