Hello friend mathsmell me apka swaghat hai. Previous post me humne dekha ki lcm and hcf kaise kare,fullform of lcm and hcf, definition of lcm and hcf in hindi aur bho dekha lcm and hcf short tricks in hindi.
Dosto aaj iss post me hum janenge bells or ghanta se related questions ki solution kaise karte hai or how to solve questions based on bells. Bahut sare competitive exams me bells or ghanta se related question puche jate hai.
Isliye dosto iss post ko dhayan se pura padhe qki iss post ko pura padne ki baad bells or ghanta se related kisi bhi questions ki jawab depayenge.
How to solve questions based on bells:
Bells or ghanta se related questions bahut he easy hote hai. Bells or ghanta ki question ki solution ki tarika janneke liye niche diye gaye step ko step by step follow kare.
Bells or ghanta se related questions bahut he easy hote hai. Bells or ghanta ki question ki solution ki tarika janneke liye niche diye gaye step ko step by step follow kare.
- Sabse pehle sabhi time interval ki LCM kare.
- Nexa, LCM ko initial time se add kare.
Finally, Lcm and initial time ki addition he hoga puche gaye questions ki answers ki kab all bells or ghanta ek sath ring hoga.
Example:1. Seven bells ring at intervals of 2, 3, 4, 6, 8, 9 and 12 minutes respectivelly. They started ringing simultaneously at 5.00 in the morning. what will be the next time when they all ring simultaneously.
Soln. Sabse pehle sabhi time intervals 2, 3, 4, 6, 8, 9 and 12 minutes ki LCM kare.
Lcm of 2, 3, 4, 6, 8, 9 and 12 min. = 72 min = 1 h. 12 min.
Lcm of 2, 3, 4, 6, 8, 9 and 12 min. = 72 min = 1 h. 12 min.
Next, LCM ko initial time 5:00 in the morning se add kare.
( 5:00 + 1:12) = 6:12 h.
( 5:00 + 1:12) = 6:12 h.
Therefore, next time sabhi bells or ghanta ek sath 6:12 in the morning me ring hoga.
Example 2: In a fire range , 4 shooters are firing at their respective targets. The first, the second, the third and the fourth shooter hit the target once in every 5 s, 6 s, 7 s and 8 s, respectively. If all of them hit their targets at 9:00 am, When they will hit their targets together again?
Soln. Sabse pehle sabhi time intervals 5, 6, 7, and 8 second ki LCM kare.
Lcm of 5, 6, 7, and 8 sec. = 840 sec. = 14 min = 0:14 h.
Lcm of 5, 6, 7, and 8 sec. = 840 sec. = 14 min = 0:14 h.
Next, LCM ko initial time 9:00 am. ki sath add kare.
( 9:00 + 0:14) = 9:14 = 9 hr 14 min.
( 9:00 + 0:14) = 9:14 = 9 hr 14 min.
Therefore, 9:14 am they hit their targets together again.
Example 3.: Six bells ring at interval of 2, 4, 6, 8, 10 and 12 sec. respectively .They started ringing simultaneously. How many times , will they ring together in 30 min.
Soln.
Sabse pehle sabhi time intervals 2, 4, 6, 8, 10 and 12 sec. ki LCM kare.
Lcm of 2, 4, 6, 8, 10 and 12 sec. = 120 sec = 2 min.
Sabse pehle sabhi time intervals 2, 4, 6, 8, 10 and 12 sec. ki LCM kare.
Lcm of 2, 4, 6, 8, 10 and 12 sec. = 120 sec = 2 min.
Therefore sabhi ghanta 2 min ki difference me ring horahahe
Questions me pucha gaye ki 30 minutes me kitne bar ek sath ring hoga.
Questions me pucha gaye ki 30 minutes me kitne bar ek sath ring hoga.
Therefore, 30 minutes me all bells [( 30/2) + 1] = 16 bar ek sath ring hoga.
I hope how to solve questions based on bells or kaise bells or ghanta se related questions ki solutions kare puri jankari in hindi post apko acha laga hoga. Agar ha to iss post ko apne dosto ki sath share kare aur agar koi questions hai to jarur comment box me puche. Thank You..
