x साह, x दिन, x घंटे, x मिनट और x सेकंड में कुल कितने सेकंड हैं?
सही उत्तर (D) 694861x है।
व्याख्या:
To convert weeks, days, hours, minutes, and seconds into total seconds: 1 week = 7 days = 7 × 24 hours = 168 hours = 168 × 3600 seconds = 604800 seconds. 1 day = 24 hours = 24 × 3600 seconds = 86400 seconds. 1 hour = 3600 seconds. 1 minute = 60 seconds. 1 second = 1 second. Thus, for x weeks, x days, x hours, x minutes, and x seconds, the total number of seconds is: x × (604800 + 86400 + 3600 + 60 + 1) = x × 694861? Wait, let's sum: 604800 + 86400 = 691200; 691200 + 3600 = 694800; 694800 + 60 = 694860; 694860 + 1 = 694861. Wait, let's check the options: 694860x or 694861x? Let's re-verify carefully: x weeks = x × 7 days = 7x days = 7 × 24 × 3600 x seconds = 604800x seconds. x days = x × 24 × 3600 seconds = 86400x seconds. x hours = x × 3600 seconds = 3600x seconds. x minutes = x × 60 seconds = 60x seconds. x seconds = x seconds. Total seconds = 604800x + 86400x + 3600x + 60x + x = 694861x. Hence, option (d) is correct.
In English (Question & Model Answer)
How many seconds in total are there in x weeks, x days, x hours, x minutes and x seconds?
The correct answer is (D) 694861x.
Explanation:
To convert weeks, days, hours, minutes, and seconds into total seconds: 1 week = 7 days = 7 × 24 hours = 168 hours = 168 × 3600 seconds = 604800 seconds. 1 day = 24 hours = 24 × 3600 seconds = 86400 seconds. 1 hour = 3600 seconds. 1 minute = 60 seconds. 1 second = 1 second. Thus, for x weeks, x days, x hours, x minutes, and x seconds, the total number of seconds is: x × (604800 + 86400 + 3600 + 60 + 1) = x × 694861? Wait, let's sum: 604800 + 86400 = 691200; 691200 + 3600 = 694800; 694800 + 60 = 694860; 694860 + 1 = 694861. Wait, let's check the options: 694860x or 694861x? Let's re-verify carefully: x weeks = x × 7 days = 7x days = 7 × 24 × 3600 x seconds = 604800x seconds. x days = x × 24 × 3600 seconds = 86400x seconds. x hours = x × 3600 seconds = 3600x seconds. x minutes = x × 60 seconds = 60x seconds. x seconds = x seconds. Total seconds = 604800x + 86400x + 3600x + 60x + x = 694861x. Hence, option (d) is correct.
