(A) 5 (B) 4 (C) 3 (D) None of the above प्रश्न . यदि किसी विशेष वर्ष में किसी महीने का अंतिम दिन बुधवार होता है , तो उस महीने में कितने सोमवार होंगे ? (A) 5 (B) 4 (C) 3 (D) उपरोक्त   में   कोई   नहीं If a month ends on a Wednesday, we can determine the number of Mondays by analyzing the distribution of days in the month. Let's break it down: 1.     If the month ends on a Wednesday, then the last day of the month is Wednesday. 2.     The previous day (Tuesday) is the 30th, and so on. To find the exact number of Mondays, we need to establish the total number of days in the month (either 28, 29, 30, or 31). However, since the day of the week is provided, let's consider the scenarios where a month ends on Wednesday. Scenario with 31 Days: If the month has 31 days and ends on a Wednesday, the distribution of day...

Q. January 12, 1980 was Saturday, what day was January 12, 1979: (A) Saturday (B) Friday (C) Sunday (D) Thursday प्रश्न . जनवरी , 12, 1980 शनिवार था , तो जनवरी 12, 1979 क्या था ? (A) शनिवार (B) शुक्रवार (C) रविवार (D) बृहस्पतिवार To determine the day of the week for January 12, 1979, given that January 12, 1980 was a Saturday, we need to consider the number of days between these two dates. 1980 is a leap year, so it has 366 days. We can calculate the number of days from January 12, 1979, to January 12, 1980: 1.     From January 12, 1979, to January 12, 1980, there are 365 days in a non-leap year. 2.     Since 1980 is a leap year, the difference in days from January 12, 1979, to January 12, 1980, is 365 days. 365 days is exactly 52 weeks and 1 day, so the day of the week will move forward by 1 day. Since January 12, 1980, is a Saturday, going back one day would mean January 12, 1979, was: (B) Friday 12 जनवरी, 1979 को सप्ता...
