Q92. Define cash flow used in Project IRR
Cash flow used in Project IRR refers to the actual cash inflows and outflows generated by a project.
Cash flow used in Project IRR is the net cash generated by a project, taking into account both inflows and outflows.
It is used to calculate the internal rate of return (IRR) of a project, which is the discount rate that makes the net present value (NPV) of all cash flows from a particular project equal to zero.
Positive cash flows represent inflows of cash, while negative cash f...read more
Q93. Plot dual cycle graph
A dual cycle graph is a graph that consists of two cycles that share exactly one common vertex.
A dual cycle graph has two cycles that are connected at one vertex.
The cycles can have different lengths and can be of any shape.
The common vertex is shared by both cycles.
Dual cycle graphs are commonly used in graph theory and network analysis.
Q94. If 5,15,45,135, ... Then
The given sequence follows a pattern of multiplying each term by 3.
The next term is obtained by multiplying the previous term by 3.
Each term is 3 times the previous term.
The pattern can be represented as: a(n) = 3 * a(n-1), where a(1) = 5.
