In simple words: Count the shaded squares out of the total squares.

Exam Tip: Always simplify fractions to their lowest terms if possible.

Question j) XL - XXV \(\Box\) L - XXX (Put < or > sign)
Answer: <
Calculation: XL - XXV = \(40 - 25 = 15\). L - XXX = \(50 - 30 = 20\). Since \(15 < 20\), the sign is <.
In simple words: Evaluate both sides using Arabic numbers before comparing.

Exam Tip: XL = 40, XXV = 25, L = 50, XXX = 30.
