In triangle ABC, AB = 7 cm, AC = 9 cm and BC = 8 cm. What is the length of the median from A to BC?
सही उत्तर: घ) 7 cm
By Apollonius' theorem, m² = (2·AB² + 2·AC² − BC²)/4 = (98 + 162 − 64)/4 = 49, so m = 7 cm.

Question: What is the value of x + y? Statement I: 2x + 3y = 12. Statement II: 4x + 6y = 24. Which is correct?
सही उत्तर: घ) Statements I and II together are not sufficient
Statement II is just statement I multiplied by 2, so together they are one equation; x + y can take many values (e.g. x = 6, y = 0 or x = 0, y = 4).

Question: What is the remainder when the positive integer n is divided by 6? Statement I: n leaves a remainder of 1 when divided by 3. Statement II: n is even. Which is correct?
सही उत्तर: ग) Statements I and II together are sufficient, but neither alone is
I alone: n could be 1, 4, 7, … (remainders 1 or 4). II alone: remainder 0, 2 or 4. Together n is even and ≡ 1 (mod 3), so n ≡ 4 (mod 6): remainder 4.
