उत्तर : 1. "Deducted from the balance sheet"
व्याख्या :

Answer: A) Deducted from the balance sheet Explanation: If an outstanding check of the previous month clears the bank (is paid by the bank) in the current month, you simply remove that check from the list of outstanding checks. If an outstanding check of the previous month does not clear the bank in the current month, the check will remain on the list of outstanding checks until the month that it does clear the bank. In the bank reconciliation process, the total amount of the outstanding checks is deducted from the balance appearing on the bank statement.

उत्तर : 2. "37.33 sec"
व्याख्या :

Answer: B) 37.33 sec Explanation: Speed = 108 km/hrenter a tunnel,, means that the train covers a distance equal to its own lengthso (108 x 5/18) = x/4 where x= length of trainhence x = 120 mtrsto pass completely train has to travel a distance = (x + tunnel length) that is 1120 mtrs.so (1120/t) = (108x5/18)t = 37.33 sec

उत्तर : 2. "Diamagnetic"
व्याख्या :

Answer: B) Diamagnetic Explanation: Paramagnetic Molecules :: If the Electronic configuration of a molecule has any unpaired electrons, then that molecule is said to be Paramagnetic. Diamagnetic Molecules :: If the Electronic configuration of a molecule has only paired or spin paired electrons, then that molecule is said to be Diamagnetic.   Here the molecule C2 has all paired electrons in its electronic configuration. So C2 is Diamagnetic. Whereas, B2 molecule has unpaired electrons. So B2 is Paramegnetic.
