-
Q2.Number System & SimplificationFind the HCF of 70 and 70.
Show answer & explanation
Answer: B — 70
HCF(70, 70) = 70. Check: HCF × LCM = 70 × 70 = 4900 = product of the numbers.
-
Q3.Logical ReasoningWhat is the angle between the hour and minute hands of a clock at 10:20?
Show answer & explanation
Answer: A — 170°
Angle = |30H − 5.5M| = |30×10 − 5.5×20| = 190°; the smaller angle is 360 − that = 170°.
