Angle made by hour in the first case will be 150 + 1\/2x and the angle made by minute hand will be 6x. In the second case, the angle made by hour hand will be 240 + 1\/2y and minute hand will be 6y.<br \/>\nWe have been given that 150+ x\/2 = 6y and<br \/>\n240 + y\/2 = 6x<br \/>\nSolving both the equations we get, x = 42.37 minutes.

We need to find integral solns for this where m&lt;60 and h&lt;12<\/p>\n<p style=\"line-height: 22.4px;\">m = 2\/11 (30h-1) or 2\/11(30h+1)<\/p>\n<p style=\"line-height: 22.4px;\">The values of h where m is an integer is h=4 m=22 and h=7 m=38.<\/p>\n<p style=\"line-height: 22.4px;\">Thus, there are two solutions (4, 22) and (7, 38).

Hence, A and D can only meet at D&#8217;s initial position. When A travels 3s, B travels 6s and reaches the point where D is initially standing. Similarly, C travels 9s and reaches D&#8217;s starting point. After the first meeting, all three meet after A completes an entire round around the square.<\/p>\n<p>So, total distance covered by A =3s+4s+4s = 11s<\/p>\n<p><strong>21)\u00a0Answer\u00a0(C)<\/strong><\/p>\n<p>The angle between the two hands at 2\u2019o clock is 60 degrees. The speed of the minute hand is 6 deg\/min and of the hour hand is 1\/2 deg\/min. The relative speed between the two hands is 5 and a half degrees\/minute. The relative distance that has to be covered is 120 degrees. ( 60 degree initial difference and 60 more ).
