Which among the following correlation coefficient values represents the strongest relationship between two variables?
Show Hint
- -0.86
- +0.68
- +0.59
- -0.05
The Correct Option is A
Solution and Explanation
Key points: 1. The closer the absolute value of \textit{r} is to 1, the stronger the correlation.
2. In this case: - \(|-0.86| = 0.86\), - \(|+0.68| = 0.68\), - \(|+0.59| = 0.59\), - \(|-0.05| = 0.05\).
3. Therefore, -0.86 represents the strongest relationship. Thus, the correct answer is (A) -0.86.

- An organization allows its employees to work independently on consultancy projects but charges an overhead on the consulting fee.
The overhead is 20% of the consulting fee if the fee is up to ₹5,00,000.
For higher fees, the overhead is ₹1,00,000 plus 10% of the amount by which the fee exceeds ₹5,00,000.
The government charges a Goods and Services Tax (GST) of 18% on the total amount (i.e., the consulting fee plus the overhead).
An employee of the organization charges this entire amount — that is, the consulting fee, overhead, and tax — to the client.
If the client cannot pay more than ₹10,00,000, what is the maximum consulting fee that the employee can charge?

- Identify the option that has the most appropriate sequence such that a coherent paragraph is formed:
P: Over time, such adaptations lead to significant evolutionary changes with the potential to shape the development of new species.
Q: In natural world, organisms constantly adapt to their environments in response to challenges and opportunities.
R: This process of adaptation is driven by the principle of natural selection, where favorable traits increase an organism’s chances of survival and reproduction.
S: As environments change, organisms that can adapt their behavior, structure, and physiology to such changes are more likely to survive.
