hello all I want to ask that I have done all the topics of Chemistry Class 12th from video but I havent touched NCERT yet.I have my board exams in 3 days so what should I do.Should I do the NCERT and back exercise questions or do pyqs.Are doing only PYQs after revision sufficient for scoring 90+

Hiii

Scoring 90+ is not possible just with the PYQs because the questions keep changing every year. And the basic key to score good marks in your boards exam is to be thorough with every sentence of your NCERT book, so I would strongly suggest you to go through the NCERT with whatever time you have left.

Question : Assertion: An increase in remittances from abroad improves the balance of payments.

Reason: Remittances are considered as invisible exports, contributing to a surplus in the current account.

Option 1: Both Assertion and Reason are true and correct explanation

Option 2: Both Assertion and Reason are true and incorrect explanation

Option 3: Assertion is true but Reason is false

Option 4: Assertion is false but Reason is true

Team Careers360 20th Jan, 2024

Correct Answer: Both Assertion and Reason are true and correct explanation


Solution : The correct answer is (a) Both Assertion and Reason are true and provide a correct explanation.

The Assertion states that an increase in remittances from abroad improves the balance of payments, which is true. Remittances refer to the money sent by individuals working abroad to their home countries. When there is an increase in remittances, it represents an inflow of foreign currency into the recipient country. This inflow contributes to the current account, specifically under the category of invisible exports or current transfers, and can help improve the balance of payments.

The Reason states that remittances are considered as invisible exports, contributing to a surplus in the current account, which is also true. Invisible exports refer to non-physical items, such as services, transfers, and investments, which contribute to the current account. Remittances fall under the category of transfers, as they involve the transfer of funds from one country to another. An increase in remittances can lead to a surplus in the current account and contribute to a positive balance of payments.

Question : What are the coordinates of the centroid of a triangle whose vertices are A (2, 5), B (–4, 0), and C (5, 4)?

Option 1: (–1, 3)

Option 2: (1, 3)

Option 3: (1, –3)

Option 4: (–1, –3)

Team Careers360 16th Jan, 2024

Correct Answer: (1, 3)


Solution : Given: The vertices are A(2, 5), B(–4, 0), and C(5, 4).
The centroid coordinates = $(x, y)$ = $\frac{(x_{1} + x_{2} + x_{3})}{3}, \frac{(y_{1} + y_{2} + y_{3})}{3}$.
Centroid coordinates $(x, y)$ = $\frac{(2 – 4 + 5)}{3}, \frac{(5 + 0 + 4)}{3}$.
Centroid coordinates $(x, y)$ = (1, 3)
So, the coordinates of the centroid of the triangle ABC are (1, 3).
Hence, the correct answer is (1, 3).
