Answer 1

Answer : t = 8 minutes.

Answer 2

Given :

At 't' minutes past 2 p.m, The Time needed by the minute hand of the Clock to show 3 p.m is found to be 3 minutes less than $[\frac{t^2}{4}]$ inutes.

⇒ $t = \frac{t^2}{4} - 3$

⇒ t² - 4t - 12 = 0

⇒ t² - 6t + 2t - 12 = 0

⇒ t(t - 6) + 2(t - 6) = 0

⇒ t = -2 or t = 6

As, Time cannot be Negative : t cannot be -2

⇒ t = 6 minutes
