Q3.MCQ
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 of $18\%$ on the total amount (the consulting fee plus the overhead). An employee of the organization charges this entire amount, i.e., 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?
Q4.MCQ
Two identical sheets $A$ and $B$, of dimensions $24 \text{ cm} \times 16 \text{ cm}$, can be folded into half using two distinct operations, $FO1$ or $FO2$.
In $FO1$, the axis of folding remains parallel to the initial long edge, and in $FO2$, the axis of folding remains parallel to the initial short edge.
If sheet $A$ is folded twice using $FO1$, and sheet $B$ is folded twice using $FO2$, the ratio of the perimeters of the final shapes of $A$ and $B$ is

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.
