An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
In 30 seconds, an electric device with a current of 15.0 A delivers approximately 2.81 x 10^21 electrons. This is calculated by first determining the total charge delivered and then dividing that by the charge of a single electron. The steps involve using the formulas for current and the properties of electric charge.

In this question, we need to determine the correct amount of profit that Mr. A should report as well as the measurement base that should be applied for the asset purchase in statement (iv).
(i) Calculation of the Correct Profit:
Mr. A's initially reported profit is ₹1 , 25 , 000 . We need to adjust this based on the information provided:
The cost of an asset of ₹25,000 has been taken as an expense.
This amount should not be an immediate expense, so it must be added back: \ ₹1 , 25 , 000 + ₹25 , 000 = ₹1 , 50 , 000
Mr. A is anticipating a profit of ₹10,000 on the future sale of a car.
Anticipated profits cannot be recognized until they are realized, so this anticipated profit should be subtracted: \ ₹1 , 50 , 000 − ₹10 , 000 = ₹1 , 40 , 000
Salary of ₹7,000 payable in the financial year has not been taken into account.
This is an expense that should reduce the profit: \ ₹1 , 40 , 000 − ₹7 , 000 = ₹1 , 33 , 000
Mr. A purchased an asset for ₹75,000 but recorded it at ₹85,000.
This does not affect the profit calculation as it relates to the balance sheet.
Thus, the correct amount of profit to be reported in the books is ₹1 , 33 , 000 .
(ii) Measurement Base for Statement (iv):
In financial accounting, assets are typically recorded at their historical cost, which is the price paid for the asset at the time of purchase.
In this case, Mr. A should have recorded the asset at its historical cost of ₹75,000, not its fair value of ₹85,000.
Therefore, the correct measurement base is (a) Historical cost .
