An examination was held during the 2 weeks of April 3rd-Sunday to 16th Saturday. There was 1 paper for the six subjects - Physics, Chemistry, Biology, Maths, English and Hindi. Only 1 paper per day No exam on Saturdays and Sundays and Holiday on April 5th. Only 3 exams were there in a week. Chemistry was before Biology and Maths was on the next day of Hindi. The day on which the paper of biology and maths were held was the same, while that for chemistry and physics was also the same. There was no exam for 3 days between Physics and the exam prior to it. Hindi exam on Tuesday and one exam between Hindi and English exam. There was at least a gap of one day between any 2 science paper. Which of the following exam was held on April 12th ?

The average of 12 numbers is 18.5. The average of first six numbers is 16.8 and that of the last seven numbers is 17.4. If the 6th number is excluded, then what is the average (correct to one decimal place) of remaining 11 numbers? 12 संख्याओं का औसत 18.5 है | पहली छः संख्याओं का औसत 16.8 है तथा अंतिम सात संख्याओं का औसत 17.4 है | यदि छठी संख्या को हटा दिया जाए, तो शेष 11 संख्याओं का औसत (एक दशमलव स्थान तक) क्या होगा ?

x is the 4th proportional to 12, 16 and 5, and 20, y, 15, 21 are in proportion. Then the value of (6x-y) is: x, 12, 16 और 15 का चौथा समानुपाती है , तथा 20, y, 15, 21 समानुपात में हैं |(6x-y) का मान है :

Two different coils have self inductane L_(1) = 16mH and L_(2) = 12mH . At a certain instant, the current in the two coils is increasing at the same rate of power supplied to th two coils is the same. Find the ratio of {:i) induced voltage {:ii) current {:iii) energy stored in the two coils at that instant.
