Program to find N-th term of series 1, 3, 12, 60, 360...in C++
In this problem, we are given a number N. Our task is to create a Program to find N-th term of series 1, 3, 12, 60, 360...in C++.Given Series1, 3, 12, 60, 360, 2520 … N TermsLet’s take an example to understand the problem, Input − N = 6Output − 2520Solution Approach:The general term formula for this one is a bit tricky. So, the increase in the series values is huge. So, there can be a few possibilities factorial or exponentials. So, we will first consider factorial, and on observing we can see the growth half as half of the ...

Read MoreExplain operation cycle method in estimation of working capital.
Operation cycle method considers total cycle of operations, from raw materials to finished goods, from accounts payable to net cash.The times taken to complete these operations are called operating cycle time.If the operating cycle is long then, requirement of working capital is less, if the operating cycle is less then, requirement of working capital is less.FormulasWorking capital = CGS(E)* D/365 + CBHere, CGS (E) = estimated cost of goods sold, D = days in operating cycle, CB = Cash/Bank balanceRM Stock = PU(E) * Cu * (Hp/365)Here, PU(E) = production units estimated, Cu = cost per unit, HP = holding ...
